Five Common Valve Types
The gate valve is used as a cut-off medium. When it is fully opened, the whole flow is straight through. At this time, the pressure of the medium is small and the loss is small. Gate valves are usually suitable for conditions that do not require frequent opening and closing, and that keep the gate fully open or fully closed. Not suitable for use as a regulator, throttling. For high-speed flow of the medium, the gate in the local open condition, can cause the vibration of the valve, and vibration, and may damage the sealing surface of the gate and valve seat, and throttling, will make the gate subjected to media erosion. From the structural form, the main difference is the form of the sealing element. According to the form of sealing components, often the gate valve is divided into several different types, such as: wedge gate valve, parallel gate valve, parallel double gate valve, wedge double gate gate, etc. Commonly used in the form of wedge gate valve and parallel gate valve.
