Gate Valve Description
The gate valve is a multi-turn valve designed for use as an isolation valve in pipelines, providing full open and close functionality. It operates by a threaded stem that drives the gate against two seats, effectively blocking the flow of fluid. The seats are typically made of metal with hard facing, such as Stellite (CoCrW) or stainless steel overlay, to ensure long-lasting performance. For specific applications, such as water service, soft seats can also be used.
Compared to other shut-off valves, gate valves require less installation space. Their multi-turn design allows for slower operation, which helps to prevent water hammer effects. Gate valves are ideal when low pressure drop and an unobstructed bore are required.
These valves are versatile and widely used in various applications, making them suitable for handling different fluids, including water, oil, steam, gas, and slurry.
