ASTM A216 WCB Gate Valve, 8 IN, CL1500, Bolted, Trim 8

8 Inch Wedge Gate Valve, ASTM A216 WCB Body, Trim 8, DN200, Class 1500 LB, RTJ Flanged.

A gate valve is a multi-turn isolation valve used for fully opening or closing pipelines. It works by moving a gate between two seats, usually metal with hard-facing for durability or soft seats for specific applications like water. The multi-turn operation prevents water hammer and requires less space than other shut-off valves. Gate valves are ideal for low pressure drop and free bore, suitable for fluids like water, oil, steam, gas, and slurry.
