Standards Overview
When you choose a swing check valve, you want to know it meets the right standards. These standards help you trust the valve’s safety, quality, and performance. Let’s look at the main standards that guide the design and use of swing check valves.
API Standards
The American Petroleum Institute (API) sets important rules for valves used in pipelines and process systems. You will find that api 6d standards are key for pipeline valves. These standards cover how the valve should be built, what materials to use, and how to test the valve. Here is a quick look at some main API standards:
| Standard | Description |
|---|---|
| API 6D | Sets requirements for pipeline valves, including design, materials, testing, and performance. |
| API 594 | Lists rules for check valves, including swing check types, covering design, materials, testing, and marking. |
API 6D swing check valves have a full port design. The clapper is the only moving part. It swings open when fluid flows and closes to stop backflow. These valves must pass strict tests to make sure they work well in oil and gas pipelines.
Note: API 594 also requires the disc nut to be secured and the disc not to swivel 360 degrees. This helps keep the valve safe and reliable.
ASME Standards
The American Society of Mechanical Engineers (ASME) gives you rules for pressure and temperature ratings. ASME B16.34 is the main standard for valve materials and pressure classes. It helps you pick the right valve for your system’s needs.
| Pressure Class | Material Group | Description |
|---|---|---|
| 150 | Carbon Steel | Good for low-pressure jobs |
| 300 | Stainless Steel | Works for higher pressure and temperature |
| 4500 | Various Alloys | Handles extreme conditions |
ASME B16.34 also checks that the valve can handle the pressure and temperature in your system. It groups materials by how strong and safe they are under different conditions.
BS Standards
British Standards (BS) are also important for swing check valves. BS 1868 is the main standard for steel swing check valves. It tells you how the valve should be made and tested.
| Standard | Description |
|---|---|
| BS 1868 | Sets rules for swing check and tilting disc check valves made of steel. |
| ISO 15761 | Lists requirements for steel check valves in oil and petrochemical plants. |
| DIN 3202 | Gives face-to-face dimensions for swing check valves. |
Swing check valves under BS 1868 use a disc that tilts open with flow and closes to stop backflow. The disc rests on the seat when there is no flow, making sure the valve stays closed and your system stays safe.
LCB Swing Check Valve Compliance
STV Valve Technology Group Co., Ltd is a top valve maker in China. They make many types of valves. Some examples are BS 1868 LCB Swing Check Valve, 10 Inch LCB Swing Check Valve, 150LB LCB Swing Check Valve, Raised Face LCB Swing Check Valve, A352 LCB Swing Check Valve, Flange End LCB Swing Check Valve, and Piston Check Valve. These valves work well and cost less. Many companies trust them for their needs.
Design Features
The lcb swing check valve is made to meet tough world rules. It comes in a 10-inch size and can handle 300LB pressure. This makes it good for hard jobs. The full port lets liquid move easily. This helps your system run better. The raised face end helps the valve fit tight and makes it easy to put in.
Here is a table that shows how the design features match the main rules:
| Feature | Specification |
|---|---|
| Design Standard | BS 1868 |
| Body Material | ASTM A352 LCB |
| Size | 10 Inch, DN250 |
| Pressure | Class 300 LB, PN50 |
| End Connection | RF Flanged |
| Face to Face Standard | ASME B16.10 |
| Test & Inspection Standard | API 598 |
| Certificates | API 6D, ISO 15848-1, API 622 |
| Dynamic Leakage Rate | < 12 PPM |
| Static Leakage Rate | < 6 PPM |
The lcb swing check valve follows rules like BS 1868, ASME B16.34, and API 6D. The full port and RF flanged ends meet DIN 3356, API 6D, and ASME B16.5 rules. You can use this valve in power plants, oil refineries, and other places. It works in many temperatures, from -29°C to +340°C. You can count on it in hot or cold places.
Material Specifications
The astm a352 lcb material makes the valve strong and tough. This steel is known for being hard, even when it is very cold. You can use it for water, gas, oil, and some harsh liquids.
Here is a table that shows what astm a352 lcb is like:
| Property | Specification |
|---|---|
| Chemical Composition | C≤0.30%, Mn≤1.00%, Si≤0.60%, impurities ≤1% |
| Mechanical Properties | Tensile strength: 450-620MPa, elongation ≥24% |
| Temperature Range | -46℃ to +343℃ |
| Industry Standards | GB12237-89, ASME B16.34 |
| Equivalent Material | A350 LF2 grade, 16Mn steel |
You get great rust protection from astm a352 lcb. Nickel and molybdenum help the valve fight strong chemicals. The material stays tough and bendy, even when it is cold. This makes the valve good for LNG, LPG, and other very cold uses. It works better than normal carbon steel in cold and harsh places.
- astm a352 lcb is used for important parts in cold valves.
- It is good for moving cold liquids like liquefied natural gas and liquid ammonia.
- It meets rules like GB12237-89 and ASME B16.34.
Testing and Inspection
You want your swing check valve to be safe and work well. STV Valve Technology Group Co., Ltd tests every valve by API 598, ASME, and BS 1868 rules. These tests look for leaks, strength, and quality.
Here is a table that shows the main test rules:
| Valve Type | Shell Test Pressure (Minimum) | Test Fluid | Remarks |
|---|---|---|---|
| Flanged Valves | 1.5 times rated pressure at 38°C (100°F) | Water, air, inert gas | Used for many valve sizes and pressure classes |
| Butt Weld Valves | 1.5 times rated pressure at 38°C (100°F) | Water, air, inert gas | Same as flanged valves |
| Threaded/Socket Weld Valves | 1.5 times rated pressure at 38°C (100°F) | Water, air, inert gas | For Class 2500 or lower per ASME B16.34 |
| Class 800 Valves | 1.5 times rated pressure at 38°C (100°F) | Water, air, inert gas | Specific to Class 800 valves (API 602) |
| API 609 Cat A Valves | 1.5 times max Cold Working Pressure (CWP) | Water, air, inert gas | For valve categories in API 609 |
Each valve must pass a shell test at 1.5 times its rated pressure. This makes sure the valve will not leak or break when used. The tests use water, air, or safe gas to check for leaks and strength. These careful checks help you trust every lcb swing check valve you use.
