Knowledge: The role of flange gate valve

Flange gate valve

Flange gate valve is used as a cut-off medium. When fully open, the entire flow is straight, and the pressure loss of the medium is minimal. Flange gate valves are usually suitable for working conditions that do not require frequent opening and closing, and keep the gate fully open or fully closed. It is not suitable for use as a regulator or throttle. For high-speed flowing media, the gate can cause vibration of the gate when it is partially open, and the vibration may damage the sealing surface of the gate and the valve seat, and throttling will cause the gate to be eroded by the medium. In terms of structural form, the main difference is the form of the sealing element used. According to the form of the sealing element, gate valves are often divided into several different types, such as: wedge gate valve, parallel gate valve, parallel double-disc gate valve, wedge double-disc gate, etc. The most commonly used forms are wedge gate valves and parallel gate valves.
