    Frequently Asked Questions
     

     

    Q: What is knife type gate valve?

    A: A knife type gate valve is a valve that controls the flow of fluid through a blade-shaped disc. The disc can be rotated or raised and lowered perpendicular to the flow direction of the fluid to open and close the valve.

    Q: What is the basic structure of knife type gate valve?

    A: The knife gate valve is usually composed of a valve body, a valve plate (blade), a valve seat and an actuator (such as manual, electric, pneumatic, etc.). The bottom of the valve plate has a knife-shaped bevel cut, which can effectively cut off the debris in the medium when closed to prevent blockage.
