Unlike globe or butterfly valves, gate valves create minimal pressure drop when fully open due to their straight-through flow design. The valve operates through the vertical movement of a disc (gate or wedge) that rises perpendicular to the flow path when opened.<\/p>\n<div class=\"blockquote\">\n<p>&#8220;Gate valves are on-off valves to open and close the flow of the fluid in a pipeline. The valve is opened and\/or closed by the vertical movement of a disc on the valve&#8217;s seat.&#8221;<\/p>\n<\/p><\/div>\n<h3>Key Advantages of Gate Valves<\/h3>\n<div class=\"pros-cons\">\n<div class=\"pros\">\n<h4 class=\"pros-title\">Advantages<\/h4>\n<ul class=\"custom-list\">\n<li>Bi-directional flow capability<\/li>\n<li>Minimal pressure drop when fully open<\/li>\n<li>Excellent sealing capabilities when closed<\/li>\n<li>Suitable for slurries and viscous liquids<\/li>\n<li>Available in large sizes for major pipeline applications<\/li>\n<li>Inherently fire-safe with metal-to-metal seating<\/li>\n<li>Easy maintenance and disassembly<\/li>\n<\/ul><\/div>\n<div class=\"cons\">\n<h4 class=\"cons-title\">Limitations<\/h4>\n<ul class=\"custom-list\">\n<li>Relatively slow opening and closing times<\/li>\n<li>Not suitable for throttling applications<\/li>\n<li>Potential for erosion of seat and disk<\/li>\n<li>Limited pressure capabilities in some designs<\/li>\n<li>Larger installation footprint compared to some valve types<\/li>\n<li>Potential for stem leakage over time<\/li>\n<li>May be difficult to repair in case of failure<\/li>\n<\/ul><\/div>\n<\/p><\/div>\n<\/section>\n<section id=\"api-asme-standards\">\n<h2>API and ASME Standards for Gate Valves<\/h2>\n<p>The American Petroleum Institute (API) and American Society of Mechanical Engineers (ASME) have established comprehensive standards that govern the design, manufacturing, testing, and marking of gate valves.
