Flexible Wedge
Gate Valve, ASTM A216 WCB Body, 14 IN/DN350, 2500 LB, OS&Y, Bolted Bonnet, RTJ Flanged.
Gate valves are multi-turn valves designed for isolation, allowing for complete opening or closing of the pipeline. They operate via a threaded stem that moves the gate to seal against two seats, blocking fluid flow. Typically featuring metal seats with hard facing (like stellite CoCrW or SS overlay) for durability, they can also be equipped with soft seats for applications such as water. Gate valves require less installation space than other shut-off valves and their gradual operation helps mitigate water hammer. They are versatile and suitable for various fluids including water, oil, steam, gas, and slurry.
