Gate Valve Introduction
Gate valves are multi-turn valves used for isolating pipelines with full open and close capability. They operate with a threaded stem that moves the gate into two metal seats to block fluid flow, typically featuring hard-facing materials like Stellite CoCrW or stainless steel overlay for durability, though soft seats are available for specific applications such as water. Compared to other shut-off valves, gate valves require less installation space and their slow operation helps prevent water hammer. They are ideal for applications needing low pressure drop and unobstructed flow, and are suitable for various fluids, including water, oil, steam, gas, and slurry.
