How Does a Gate Valve Work?

The gate valve can only be fully opened or closed and cannot be used to regulate flow. Its working principle is that the gate plate moves up and down with the valve stem, and the valve stem has trapezoidal threads. The valve stem moves up and down via the nut at the top of the valve and the guide groove on the valve body. The movement of the gate The gate's movement is perpendicular to the flow direction of the fluid medium in the pipeline. A gate valve is a valve in which the closure (gate) moves in the vertical direction of the passage's central line. The gate valve in the pipeline can only be used for full opening and full closing and cannot be adjusted or throttled.

A gate valve is a type of valve that has many applications. It is typically used to block devices with a diameter of DN 50 mm. A gate valve is sometimes used to block devices with small diameters. The gate valve is used as a medium cutoff. At this time, the pressure loss in medium operation is the smallest. Gate valves are typically used in situations where the gate does not need to be opened and closed frequently, and they maintain the gate fully open or fully closed. not suitable for use with regulation or throttling.
