Common Valve Symbols in P&IDs

Understanding the symbols for different valve types is essential for correctly interpreting P&IDs. Each valve type has a unique symbol that provides insight into its function and operation within the system.

Gate Valve Symbol

The gate valve symbol is typically represented as a rectangular box with a horizontal line inside. This symbol indicates the valve’s function of allowing or stopping fluid flow by raising or lowering a gate-like barrier within the valve body.

Gate valve symbol and its representation in P&ID

Ball Valve Symbol

The ball valve symbol is usually represented as a symbol with a circle containing a horizontal line or a small circle inside, indicating the valve’s on/off state. This symbol reflects the function of a ball valve, which controls fluid flow by rotating a sphere with a hole through it.

Ball valve symbol with explanation

Butterfly Valve Symbol

The butterfly valve symbol in P&IDs typically consists of a circle bisected by a diagonal line. This symbol indicates the function of the butterfly valve, which uses a rotary disc to control fluid flow by rotating perpendicular to the flow direction.

Butterfly valve symbol in engineering diagrams

Check Valve Symbol

Check valves are important one-way flow control elements in piping systems. Their symbol in P&IDs usually consists of a circle (representing the valve body), an internal arrow (indicating the direction of flow), and a line through the circle (indicating the non-return mechanism).

Types of Check Valves:

  • Swing check valve
  • Lift check valve
  • Ball check valve

Multi-Way Valve Symbols

Beyond the basic valve types, P&IDs also feature symbols for more complex multi-way valves that control flow in multiple directions.

Two-Way Valves

In a P&ID, the symbol for a two-way valve usually consists of two equilateral triangles pointing toward each other. This design clearly indicates the valve’s function of controlling fluid flow between two ports, typically used to open or close the flow path.

Three-Way and Four-Way Valves

The symbol for a 3-way valve typically shows a valve with three connections, either in a “T” shape or a circle with three outlets. Three-way valves can be either L-shaped or T-shaped, depending on how the fluid connections are arranged.

Four-way valve symbols indicate a valve with four connections, similar in shape to a cross. These valves allow fluid to flow between multiple directions and are suitable for more complex systems requiring directional control.

Valve States and Position Indicators

Valve symbols in P&IDs also convey information about their default positions and operational states.

Normally Open (NO) and Normally Closed (NC) Valves

Valves in P&IDs can be labeled as normally open (NO) or normally closed (NC). These terms describe the default position of the valve when no external force is applied:

  • Normally Open (NO): This valve allows fluid to pass by default. It is usually indicated by a specific symbol or the letters “NO” on the diagram.
  • Normally Closed (NC): This valve prevents fluid flow unless activated. Look for the “NC” label or related symbol on the P&ID to identify it.

Bistable Valves

Bistable valves have a unique function. Unlike conventional valves, they maintain their final position during a power failure. This means if a bistable valve is opened during a power failure, it will remain open until an external action changes its state. P&IDs indicate this with a different symbol to alert operators to this behavior.

Valve Actuator Symbols in P&IDs

Valve actuators play a crucial role in the functional depiction of valves within P&IDs. These diagrams use specific symbols and notations to convey how an actuator operates a valve within a control system.

Visual Representation

In P&IDs, an actuator is typically represented as a line extending from the valve’s central point. A smaller symbol is usually placed atop this line, indicating the type and method of actuation. Common types include:

Manual Actuators

Represented by symbols resembling handles or wheels, indicating human operation is required.

Electric Actuators

Typically shown with symbols containing an “E” or motor representation, indicating electrical power operation.

Pneumatic/Hydraulic Actuators

Represented by symbols showing pressure cylinders or diaphragms, indicating fluid pressure operation.

Different types of valve actuator symbols

Failsafe Position Indicators

Actuators also signal their failsafe positions in P&IDs. This is usually shown through a line and arrow:

  • If the arrow points toward the valve symbol, it indicates a failsafe closed position.
  • An arrow pointing away signifies a failsafe open position.
  • The failsafe status might be labeled with abbreviations like “FO” for failsafe open, or “FC” for failsafe closed.

End Connection Representations in P&IDs

End connections are an essential part of P&IDs because they illustrate how valves connect to process lines. In P&IDs, these connections use specific symbols and lines to indicate the connection type.

Connection Type Symbol Representation Description
Flange Connection Two parallel lines with a break or filled square Indicates a removable connection using bolted flanges
Threaded Connection Series of dotted lines or circles Indicates a threaded pipe connection
Welded Connection Solid continuous line with solid circle Indicates a permanent welded connection
Socket Weld Connection Solid lines with small solid squares Distinguished from butt welds by distinctive symbols

Different types of end connection symbols in P&IDs

Process Lines in P&IDs

Process lines in P&IDs serve as the backbone for illustrating flow and connectivity within a system. They delineate the pathways through which fluids or gases travel, using various conduits such as pipes, tubes, or hoses.

Key Functions of Process Lines

  • Depicting Flow Pathways: These lines visually map out the direction and route of the process flow, aiding in understanding system design and operation.
  • Providing Crucial Details: Each line is annotated with essential information, including the component’s classification, dimensions, and insulation requirements.
  • Enhancing System Design: By providing a clear representation of process flow, these lines enable engineers to design efficient systems and quickly identify potential problem areas.

Process line symbols and their meanings in P&IDs

Signal Lines in P&IDs

Signal lines in P&IDs illustrate the type of signal—electric, pneumatic, or data—that communicates information between components, instruments, and control system computers. These are typically represented by different line styles to distinguish them from process lines.

Electrical Signals

Usually represented by dashed lines, these indicate electrical communication between instruments and controllers.

Pneumatic Signals

Often shown as dotted lines, these represent air-pressure signals used in pneumatic control systems.

Digital/Data Signals

Typically depicted as dash-dot lines, these indicate digital communication networks or fieldbus systems.

Understanding Tag Numbers in Valve Symbols

Tag numbers are a critical aspect of valve symbols in P&IDs. These alphanumeric codes encapsulate vital information about the valve, including properties of the media being controlled and its function within the system.

Components of a Typical Tag Number

A standard tag number might follow this format: XX-YYY-ZZ, where:

  • XX: Indicates the type of instrument or valve
  • YYY: Represents the loop or system number
  • ZZ: Denotes the specific function or sequence number

Tag numbers provide a means to catalog and maintain the complex array of components in P&IDs, making them essential for system documentation and maintenance.

Practical Tips for Reading Valve Symbols

Interpreting valve symbols on P&IDs requires practice and attention to detail. Here are some practical tips to help you become proficient:

Start with the Basics

  • Learn the fundamental valve types first (gate, ball, check)
  • Understand the basic flow direction indicators
  • Familiarize yourself with common actuator symbols

The Key Differences Between Globe Valve and Angel Valve

Cross-section diagram of a standard globe valve showing internal components and flow path
Selecting the right valve type is crucial for ensuring optimal performance, safety, and efficiency in industrial fluid control systems. Globe valves and what are sometimes mistakenly called “angel valves” (correctly termed “angle valves”) are two common options that engineers and procurement specialists often compare. While they share some similarities, these valve types serve different primary purposes and offer distinct advantages in various applications. This comprehensive guide will clarify the terminology confusion and provide you with the essential information needed to make an informed selection decision for your specific requirements.

Clarification of Terminology: Angel Valve vs. Angle Valve

Before diving into the comparison, it’s important to address a common terminology confusion. The term “angel valve” is typically a misspelling or mispronunciation of “angle valve.” There is no industrial valve type officially called an “angel valve.” What people refer to when using this term is actually an angle valve – a specific configuration of valve where the inlet and outlet ports are positioned at a 90-degree angle to each other.

Figure 1: Terminology clarification – “Angel Valve” is a common misnomer for “Angle Valve”

Angle valves are actually a variation of globe valves, designed with a specific body configuration to accommodate piping layouts where a 90-degree turn is required. Throughout this article, we’ll use the correct terminology “angle valve” when discussing this valve type and compare it with standard globe valves to help you understand their key differences and applications.

Design and Construction Differences

The fundamental differences between standard globe valves and angle valves begin with their physical design and construction. Understanding these structural variations is essential for proper selection and application.

Globe Valve Design

Standard globe valves feature a spherical body with an internal baffle that divides the valve body into two chambers. The flow path through a globe valve typically forms an “S” shape as fluid enters one side of the valve, travels around the baffle, and exits through the opposite side. This design creates a linear flow path where the inlet and outlet ports are aligned on the same axis.

Figure 2: Cross-section of a standard globe valve showing internal components and flow path

Angle Valve Design

Angle valves (sometimes incorrectly called “angel valves”) feature a body design where the inlet and outlet ports are positioned at a 90-degree angle to each other. This creates an “L” shaped flow path through the valve. The internal components, including the disc, stem, and seat, are similar to those found in standard globe valves, but the body configuration is modified to accommodate the angled flow path.

Figure 3: Cross-section of an angle valve showing the 90-degree flow path and internal components

Key Structural Differences

Feature Standard Globe Valve Angle Valve
Body Configuration Spherical with straight-through flow path L-shaped with 90-degree flow path
Port Alignment Inlet and outlet on same axis Inlet and outlet at 90-degree angle
Internal Baffle Pronounced, creating S-shaped flow Modified to accommodate angled flow
Body Material Cast iron, bronze, stainless steel, etc. Same materials as globe valves
Bonnet Design Vertical to body Angled relative to inlet

Primary Function and Applications

While both valve types can regulate fluid flow, they excel in different applications due to their unique design characteristics. Understanding these functional differences is crucial for selecting the right valve for your specific requirements.

Globe Valve Functions

Standard globe valves are primarily designed for precise flow regulation and throttling applications. Their design allows for accurate control of flow rates, making them ideal for systems where flow modulation is critical. They are also effective for applications requiring tight shut-off capabilities.

Common Globe Valve Applications:

  • Precise flow control in process systems
  • Throttling services in steam lines
  • Feed water regulation in boiler systems
  • Control valve applications in oil and gas processing
  • Chemical processing where precise flow regulation is required
  • HVAC systems for temperature control

Angle Valve Functions

Angle valves (often mistakenly called “angel valves”) combine flow regulation capabilities with space-saving design. Their 90-degree configuration makes them particularly useful in piping systems where a change in flow direction is required. They also typically offer lower pressure drop compared to standard globe valves with additional elbows.

Common Angle Valve Applications:

  • Space-constrained piping systems requiring direction change
  • Bottom outlet connections on tanks and vessels
  • Radiator connections in heating systems
  • Compressed air systems where direction changes are needed
  • Water supply connections to fixtures and equipment
  • Systems where minimizing pressure drop is important

Figure 4: Comparison of typical applications for globe valves vs angle valves in industrial settings

Flow Characteristics and Performance

The flow characteristics of globe valves and angle valves differ significantly due to their distinct internal geometries. These differences affect pressure drop, flow capacity, and overall system performance.

Pressure Drop Comparison

Pressure drop is a critical consideration when selecting valves for fluid systems. It refers to the reduction in pressure that occurs as fluid flows through a valve. Higher pressure drops require more energy to maintain flow rates, potentially increasing operational costs.

Figure 5: Pressure drop comparison between globe valves and angle valves at various flow rates

Globe Valve Flow Characteristics

Standard globe valves typically exhibit higher pressure drops due to their S-shaped flow path. The fluid must change direction multiple times as it navigates around the internal baffle, resulting in increased turbulence and energy loss. However, this same characteristic provides excellent throttling control and precise flow regulation.

The flow coefficient (Cv) values for globe valves are generally lower than those of similarly sized gate or ball valves, indicating more restricted flow. However, they offer superior control characteristics, especially at partial openings.

Angle Valve Flow Characteristics

Angle valves generally produce lower pressure drops compared to a standard globe valve combined with an elbow fitting. The single 90-degree turn in the flow path creates less turbulence than the multiple direction changes in a standard globe valve. This makes angle valves more efficient in applications where minimizing pressure loss is important.

The flow coefficient (Cv) values for angle valves are typically higher than those of standard globe valves of the same size, indicating better flow capacity. This can be advantageous in systems where maintaining flow rates with minimal pressure loss is critical.

Flow Path Comparison

Flow Characteristic Standard Globe Valve Angle Valve
Flow Path S-shaped with multiple direction changes L-shaped with single 90-degree turn
Pressure Drop Higher Lower (compared to globe valve + elbow)
Flow Coefficient (Cv) Lower Higher
Throttling Control Excellent Good
Flow Velocity More restricted Less restricted

Installation and Space Requirements

The installation requirements and space considerations for globe valves and angle valves differ significantly, which can be a decisive factor when selecting the appropriate valve type for specific piping layouts.

Figure 6: Comparison of installation space requirements for globe valves vs angle valves

Globe Valve Installation Considerations

Standard globe valves require straight-line piping configurations, as their inlet and outlet ports are aligned on the same axis. When a change in flow direction is needed, additional fittings such as elbows must be installed. This increases the overall space requirements, adds potential leak points, and contributes to higher pressure drops in the system.

Globe valves also require sufficient clearance above the valve for stem movement during operation and for maintenance access. The bonnet and stem typically extend vertically from the valve body, necessitating vertical clearance that may be constrained in some installations.

Angle Valve Installation Advantages

Angle valves offer significant space-saving advantages in piping systems where a change in flow direction is required. Their integrated 90-degree design eliminates the need for a separate elbow fitting, reducing the overall installation footprint, decreasing the number of potential leak points, and minimizing pressure drop.

This space-saving characteristic makes angle valves particularly valuable in cramped equipment rooms, congested piping areas, and applications where multiple direction changes are needed in a limited space. The reduced number of joints also decreases installation time and maintenance requirements.

Angle Valve Space Advantages

  • Eliminates need for separate elbow fitting
  • Reduces overall installation footprint
  • Decreases number of potential leak points
  • Lowers installation costs and time
  • Simplifies piping layout in tight spaces

Globe Valve Space Limitations

  • Requires additional elbow for direction changes
  • Needs more installation space
  • Creates additional potential leak points
  • Increases installation complexity
  • Requires more vertical clearance for stem

Maintenance and Actuation Considerations

Maintenance requirements and actuation options are important factors to consider when selecting between globe valves and angle valves for specific applications. These considerations affect long-term operational costs, reliability, and system integration capabilities.

Maintenance comparison showing disassembled globe valve and angle valve components

Figure 7: Maintenance comparison showing disassembled globe valve and angle valve components

Maintenance Comparison

Maintenance Aspect Globe Valve Angle Valve
Seat Replacement Typically requires full disassembly Similar to globe valve, requires disassembly
Packing Maintenance Accessible from bonnet, can often be replaced under pressure Similar accessibility to globe valve
Disc Replacement Requires bonnet removal Requires bonnet removal
Overall Accessibility Good, with vertical access required Good, may be easier in some configurations
Frequency of Maintenance Moderate, especially for throttling applications Similar to globe valve

Actuation Options

Both globe valves and angle valves can be equipped with various actuation systems to control their operation. The choice of actuation depends on the specific application requirements, control system integration, and operational preferences.

Figure 8: Various actuation options for globe and angle valves

Manual Actuation

Both valve types commonly use handwheel operators for manual actuation. The turning effort required depends on valve size, pressure rating, and application. For larger valves or higher pressure applications, gear operators may be used to reduce the required operating torque.

Electric Actuation

Electric actuators can be mounted on both globe and angle valves for remote operation. These actuators convert electrical signals into mechanical movement to operate the valve. They are ideal for automated systems and applications requiring precise control.

Pneumatic/Hydraulic Actuation

Pneumatic and hydraulic actuators use compressed air or hydraulic fluid to generate the force needed to operate the valve. These systems are commonly used in process control applications and hazardous environments where electrical systems may pose risks.

Advantages and Disadvantages Summary

Understanding the comparative strengths and limitations of globe valves and angle valves is essential for making an informed selection decision. The following summary highlights the key advantages and disadvantages of each valve type.

Figure 11: Industry-specific applications for globe valves and angle valves

Oil and Gas

In oil and gas applications, standard globe valves are typically preferred for mainline flow control and blowdown services due to their excellent throttling capabilities and robust construction. Angle valves are commonly used in drain applications, sampling points, and where space constraints exist.

Power Generation

Power plants often use globe valves for steam control and feedwater regulation due to their precise control characteristics. Angle valves find application in boiler drain systems, instrument connections, and areas where piping layout benefits from the 90-degree configuration.

Chemical Processing

Chemical processing facilities typically use globe valves for precise flow control of process fluids. Angle valves are preferred for reactor vessel connections, tank bottom outlets, and areas where corrosive fluids require minimal dead spaces to prevent fluid trapping.

Conclusion

The choice between a globe valve and an angle valve (sometimes mistakenly called “angel valve”) depends on your specific application requirements, space constraints, and system design considerations. Globe valves excel at precise flow regulation and throttling in straight-line configurations, while angle valves offer space-saving advantages and reduced pressure drop in applications requiring a 90-degree change in flow direction.

Understanding the key differences in design, flow characteristics, installation requirements, and maintenance considerations is essential for making an informed selection decision. By carefully evaluating your specific needs against the comparative advantages and limitations of each valve type, you can select the optimal solution for your fluid control system.

Remember that both valve types are valuable tools in the fluid control arsenal, each with its own strengths and ideal applications. The “best” choice is always the one that most effectively meets your specific requirements while considering factors such as performance, space constraints, maintenance access, and long-term operational costs.

Frequently Asked Questions

What is the difference between a reducer port and a full port ball valve?

A reducer port ball valve has an internal flow passage that is smaller than the connecting pipe size, while a full port (full bore) valve has an internal passage that matches the pipe diameter. Reducer port valves typically offer more economical construction, controlled flow characteristics, and are suitable for applications where maximum flow capacity is not critical. They may create slightly higher pressure drop compared to full port designs.

What does CF8 body material mean?

CF8 is the ASTM designation for cast stainless steel that corresponds to AISI 304 (18-8) stainless steel. The “C” indicates it’s a corrosion-resistant alloy, “F” denotes the chromium-nickel content, and “8” indicates a maximum carbon content of 0.08%. CF8 offers excellent corrosion resistance, good mechanical properties, and suitability for temperatures up to 800°F (427°C), making it ideal for many industrial applications.

Is this valve suitable for steam applications?

The 1pc Ball Valve with CF8 body and PTFE seats has limited suitability for steam applications. While the CF8 body material can handle high temperatures, standard PTFE seats are typically rated for saturated steam up to 150 PSI (approximately 185°C/365°F). For higher steam pressures or superheated steam, specialized seat materials or different valve designs may be required. Always verify the specific temperature and pressure ratings for your intended steam application.

What is the advantage of a one-piece body design?

A one-piece (1pc) body design offers several advantages over multi-piece constructions. It eliminates potential leak paths between body components, provides greater structural integrity, reduces maintenance requirements, and often results in a more compact envelope size. The unified casting also typically offers better pressure containment capabilities and simplified installation. These benefits make one-piece designs particularly valuable in applications where reliability and minimal maintenance are priorities.

Can this valve be automated?

While the standard configuration features a manual lever handle, this valve can be equipped with an ISO 5211 mounting pad for automation. This standardized mounting pattern allows for the attachment of pneumatic or electric actuators. When requesting a valve for automated service, specify the need for an ISO mounting pad and provide details about your control requirements to ensure compatibility with your automation system.

T Strainer vs Basket Strainer: Comprehensive Comparison for Industrial Applications

Industrial pipeline system with T strainer vs basket strainer installation points highlighted
Selecting the right strainer type is crucial for maintaining efficient fluid systems and protecting valuable downstream equipment. The choice between a T strainer and a basket strainer significantly impacts system performance, maintenance requirements, and operational costs. This guide provides engineers, facility managers, and procurement specialists with the technical insights needed to make an informed decision based on specific application requirements.

Understanding Industrial Strainers: Basic Principles

Industrial strainers are mechanical devices designed to remove solid particles from fluid streams, protecting downstream equipment from damage and ensuring system efficiency. Before comparing specific designs, it’s important to understand the fundamental purpose these devices serve in pipeline systems.

Typical installation points for strainers in industrial pipeline systems

Strainers intercept and collect debris through a mesh element or perforated screen, allowing only clean fluid to continue through the system. This filtration process is essential for preventing damage to pumps, valves, meters, heat exchangers, and other sensitive equipment while maintaining optimal flow conditions.

T Strainer: Design and Functionality

A T strainer, named for its T-shaped configuration, is designed with the straining element positioned perpendicular to the main flow path. This creates a 90-degree turn in the pipeline where the strainer is installed.

T strainer cutaway showing internal components and flow path

Cutaway view of a T strainer showing internal components and flow path

Key Design Features

  • T-shaped body with the straining element in the vertical section
  • Straight-through flow path with 90-degree diversion to the strainer basket
  • Removable cover for access to the straining element
  • Available in cast or fabricated construction
  • Typically installed in horizontal pipelines

Construction and Materials

T strainers are commonly manufactured from materials including carbon steel, stainless steel, cast iron, and bronze. The choice of material depends on the fluid properties, operating conditions, and corrosion considerations. The straining element is typically a perforated basket or screen with mesh sizes ranging from 20 to 400 mesh, depending on the required filtration level.

Basket Strainer: Design and Functionality

A basket strainer features a cylindrical body with the straining element positioned directly in the flow path. The basket design maximizes the filtration area while maintaining a straight-through flow configuration.

Basket strainer cutaway showing internal basket element and flow path

Cutaway view of a basket strainer showing internal basket element and flow path

Key Design Features

  • Cylindrical body with in-line basket element
  • Straight-through flow path
  • Large surface area basket for maximum debris collection
  • Top-entry cover for easy basket removal and cleaning
  • Available in simplex (single basket) or duplex (dual basket) configurations

Construction and Materials

Like T strainers, basket strainers are available in various materials including carbon steel, stainless steel, cast iron, and specialized alloys for corrosive applications. The basket element typically features a perforated design with reinforcement to withstand pressure differentials. Mesh sizes range from coarse (1/8″) to fine (400 mesh) depending on the application requirements.

T Strainer vs Basket Strainer: Side-by-Side Comparison

When selecting between a T strainer and a basket strainer, several key factors must be considered. The following comparison highlights the critical differences that impact performance and suitability for specific applications.

Feature T Strainer Basket Strainer
Design & Footprint T-shaped with 90° flow diversion; Compact footprint Cylindrical with straight-through flow; Larger footprint
Straining Element Smaller surface area; Limited dirt-holding capacity Large surface area; High dirt-holding capacity
Pressure Drop Higher pressure drop due to flow path change Minimal pressure drop with straight-through design
Cleaning & Maintenance More frequent cleaning required; System typically needs shutdown Less frequent cleaning; Duplex models allow maintenance without shutdown
Installation Requirements Primarily horizontal installation; Requires less vertical clearance Horizontal or vertical installation; Requires vertical clearance for basket removal
Initial Cost Lower initial investment Higher initial investment
Long-term Operating Cost Higher due to more frequent maintenance Lower due to reduced maintenance frequency and minimal pressure drop

Pressure drop comparison between T strainer and basket strainer at various flow rates

Design & Footprint Considerations

The physical configuration of each strainer type has significant implications for system design and space requirements.

T Strainer Footprint

T strainers feature a compact design with the straining element positioned perpendicular to the flow path. This configuration requires less vertical clearance but needs additional horizontal space to accommodate the T-shaped body. The 90-degree flow diversion creates turbulence and increases pressure drop, particularly at higher flow rates.

Basket Strainer Footprint

Basket strainers maintain a straight-through flow path, which minimizes turbulence and pressure drop. However, they require significant vertical clearance above the strainer for basket removal during maintenance. The overall footprint is typically larger than a T strainer of equivalent capacity, but the flow efficiency advantages often outweigh the space considerations.

Straining Element and Dirt-Holding Capacity

The design and size of the straining element directly impact filtration efficiency, dirt-holding capacity, and maintenance frequency.

Comparison of straining elements showing the larger surface area of basket strainer (right) vs T strainer (left)

T Strainer Element

  • Smaller surface area limits dirt-holding capacity
  • Typically collects 1/3 to 1/2 the debris of equivalent basket strainer
  • Requires more frequent cleaning in applications with high debris loads
  • Mesh options typically range from 20 to 400 mesh

Basket Strainer Element

  • Large surface area maximizes dirt-holding capacity
  • Can collect 2-3 times more debris before requiring cleaning
  • Available in simplex or duplex configurations for continuous operation
  • Mesh options typically range from 1/8″ perforations to 400 mesh

Pressure Drop Impact on System Performance

Pressure drop across a strainer affects pumping requirements, energy consumption, and overall system efficiency. The strainer design significantly influences this critical performance factor.

CFD simulation comparing flow patterns and pressure distribution in T strainer (left) vs basket strainer (right)

Key Pressure Drop Considerations

  • T strainers typically create 2-3 times higher pressure drop than equivalent basket strainers due to the 90-degree flow diversion
  • Pressure drop increases as debris accumulates, occurring more rapidly in T strainers due to smaller capacity
  • Systems with T strainers often require larger pumps to overcome additional pressure losses
  • Basket strainers maintain minimal pressure drop with clean elements, typically less than 1 psi in properly sized units
  • Energy costs associated with overcoming pressure drop should be factored into total cost of ownership calculations
