API WCB Gate Valve with Extended Stem Features

Gate valve is a valve that the valve plate moves along the vertical direction in the pipeline.

Advantages of gate valve:
1. Small fluid resistance
2. The torque for opening and closing is small, so it is easy to open and close.
3. The medium flowing direction is not restricted, and it doesn't disturb flowing and reduce the pressure of pipeline.
4. Short length structure
5. Good sealing performance
6. Simple shape, good casting process, widely used
