What is a gate valve?

The gate valve is a multi-turn valve that is installed in the pipeline as an isolation valve for full open and close service.
The valve is operated by a threaded stem forcing the gate to the two seats and blocking the fluid. The seats are normally metal with hard facing(stellite CoCrW or SS Overlay) to ensure a long working life. It can also be a soft seat for specified services like water.
