Large dimension valves that operate at high pressures, Valves that need to be controlled from a remote location, Valves that require, for the nature of the process, a very fast open or close operation, Pneumatic actuators (pneumatic control valves use this type frequently). Discs are generally manufactured in forged steel and are often reinforced (hard faced) to enhance the mechanical properties of the base material.
395mm mirror arm, 12.5 section drive belt. Here you can see the main parts of the gate valve. The high velocity of the flow in the partially open valve may cause erosion of the disc and seating surfaces and also creates vibration and noise.
