Introduction to Gate Valves
Gate valves are used as shut-off media, and when fully opened, the entire flow is straight through, resulting in minimal pressure loss during the operation of the medium. Gate valves are usually suitable for working conditions that do not require frequent opening and closing, and keep the gate fully open or closed. Not suitable for use as a regulator or throttle. For high-speed flowing media, the gate may vibrate when partially opened, and the vibration may damage the gate

The types of gate valves can be divided into wedge gate valves and parallel gate valves according to the sealing surface configuration. Wedge gate valves can also be divided into single pole, double plate, and elastic gate valves; Parallel gate valves can be divided into single gate plate and double gate plate. According to the thread position of the valve stem, it can be divided into two types: rising stem gate valves and hidden stem gate valves.
