Air source pressure reducing valve

A pressure reducing valve, also called a regulator, functions by adjusting a high input pressure to a specified output pressure so that it does not change due to changes in flow or fluctuations in origination pressure.

A pneumatic pressure reducing valve consists of an actuator and an adjusting device. The actuator is a pushing element of the regulating valve, generating a pushing force corresponding to the pressure of the control signal, which moves the adjusting device. The air filtration pressure reducing valve body is an adjusting element of a pneumatic pressure reducing valve that is in direct contact with the adjusting medium and adjusts its flow. The hydraulic cylinder is using compressed air as the power source, using the rotation of the piston to drive the crank arm to rotate 90°, so as to realize the automatic opening and closing of the valve.

Adjustment range: The adjustment range is the range in which the output pressure P2 of the pressure reducing valve can be adjusted, and a certain correctness must be ensured within this range. The size of the regulating range has a lot to do with the rigidity of the regulating spring.

Pressure characteristics: Pressure characteristics are the ups and downs of the output pressure due to the ups and downs of the input pressure when the flow rate g is at a certain value. As the output pressure decreases, the performance of the safety valve from the pressure reducing valve supplier increases. The output pressure must be lower than the input pressure, and this value does not change to a large extent.

Flow characteristics of pressure reducing valves for liquefied petroleum gas: Flow characteristics are the persistence of the change in output pressure with a change in flow rate g over the input pressure - time. The change in output pressure is correct as the flow rate g changes. Usually, the fluctuations are smaller when the output pressure is lower.
