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
