API 600
Gate Valve, ASTM A351 CF8 Body, 10 Inch/DN250, 2500 LB, PN420, RTJ Flanged, OS&Y.
Gate valves are multi-turn valves designed for full isolation, either fully open or closed. A threaded stem operates the valve, pressing the gate against two seats to block the fluid flow. Typically, the seats are metal with hard facing materials like stellite CoCrW or SS overlay for durability, though soft seats are available for specific uses like water. These valves require less installation space compared to other shut-off types and their gradual operation minimizes water hammer. Gate valves are versatile, suitable for a range of fluids including water, oil, steam, gas, and slurry.
