The gate valve is used as a cut-off medium, and the whole flow is straight through when fully open, and the pressure loss of the medium operation is the smallest at the time. Gate valves are generally suitable for working conditions that do not require frequent opening and closing, and keep the wedge fully open or fully closed.
Not suitable for regulating or throttling usage. For high-speed flowing media, the wedge may vibrate when the valve is partially opened, and the vibration may damage the sealing and the valve seat, and throttling will cause the gate to be eroded by the medium. From the structural form, the main difference is the form of the sealing that valve used. According to the form of the sealing, the gate valve is often divided into several different types, such as: wedge gate valve, parallel gate valve, parallel double wedge gate valve, and so on. The most common forms are wedge gate valves and parallel gate valves.
