Guidance on selection of various valves

The gate valve is used as a cut-off medium, and the whole flow is straight when it is fully opened. At this time, the pressure loss of the medium operation is small. Gate valves are usually suitable for working conditions that do not need to be opened and closed frequently, and keep the sensor plate fully open or fully closed. Not suitable for use as regulation or throttling. For high-speed flowing medium, the gate may cause vibration of the gate under the condition of partial opening, and the vibration may damage the sealing surface of the gate and the valve seat, and the throttling will cause the gate to suffer the erosion of the medium. From the structural form, the main difference is the form of the sealing element used. According to the form of sealing elements, gate valves are often divided into several different types, such as: wedge valve, parallel gate valve, parallel double gate valve, wedge double gate valve, etc. Commonly used forms are wedge type valve and parallel type gate valve.
