Gate Valve
- Aug 29, 2018 -

Gate valve is used as the cut-off medium. When fully open, the whole flow is through. At this time, the pressure loss of medium operation is minimal.Gate valves are generally designed to operate under conditions that do not require frequent opening and closing and keep the gate fully open or fully closed.Not intended for use as an adjustment or throttling.For high-speed flowing media, gate plate can cause the vibration of gate under local open condition, and the vibration may damage the sealing cover of gate plate and seat, and the throttle will cause gate plate to suffer the erosion of medium.From the structural form, the main difference is the form of the sealing element used.According to the form of sealing element, gate valve is usually divided into several different types, such as wedge gate valve, parallel gate valve, parallel double gate valve, wedge double gate brake, etc.The most commonly used form is wedge gate valve and line gate valve.
