Funcation description:
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
