A valve whose gate plate moves vertically towards the center of the passage can become a gate valve. Its function is to cut in pipes. The gate structure is similar to that of an open water conveyance channel. The largest valve size is suitable for cutting devices with DN ≥ 50mm, and gate valves are occasionally selected for small diameter cutting devices.

The division of gate valves can be carried out from multiple dimensions in different ways, which is relatively complex to distinguish. According to the sealing surface, it can be divided into wedge shaped rams and parallel rams, and wedge shaped rams can be divided into single ram, double ram, and elastic ram; The parallel ram can be Fengcheng single ram and double ram. If divided by location, it can be divided into exposed pole type and concealed pole type.

The working direction of the gate plate is special, and the movement direction is vertical to the fluid. The gate valve can only be adjusted by two parties, fully open or fully closed, without intermediate adjustment. The number of sealing surfaces is 2. The common mode gate valves (gate valve manufacturers) are wedge shaped, with different included angles, but generally 50 degrees. When the temperature is low, it is 2 degrees and 52 minutes.
