Valve Description
A gate valve is a multi-turn isolation valve for fully opening or closing pipelines. It operates with a threaded stem to shift a gate between metal seats, which may have hard-facing for durability or soft seats for specific applications like water. Compact and effective,
gate valves prevent water hammer and are suited for low pressure drop and free bore. They are widely used with fluids including water, oil, steam, gas, and slurry.
