Pneumatic Pressure Control Valve

Pneumatic pressure control valve  is capable of regulating the system pressure to adjust the force on the hydraulic piston rod or the torque on the hydraulic motor shaft. Pressure relief valves are used to set the maximum pressure in the circuit and prevent it from being overloaded. Pneumatic pressure control valve permanently maintain the output pressure at the set value while preventing overloading of the equipment. Unloading valves are designed for economic pressure control in accumulator operating circuits and are used as a power source for emergency control.

Classification of pneumatic pressure control valve

In the pneumatic transmission system , all pressure control valves work on the principle of balance between air pressure and spring force, which can be divided into the following three categories:

1. Pressure reducing valve. Also known as pressure regulating valve, setting device (precision pressure reducing valve), etc., it plays the role of pressure reducing and stabilizing;

2. Overflow valve. Also known as safety valve, pressure-limiting shut-off valve, etc., it plays the role of pressure-limiting safety protection;

3. Sequence valve and balance valve. Depending on the pressure of the gas circuit, some control is performed.
