Hankun Company can provide all accessories for pneumatic actuators such as limit switches, solenoid valves, air filter regulators, positioners, etc. For international customers, we can provide international brands such as ROTORK, SIEMENS, Honeywell, Emerson and other mainstream brands to meet all customer requirements.

The air filter regulator is an auxiliary device of the pneumatic actuator combination unit. After inputting 0.3～1.0MPa compressed air, it can provide 0.1～1.0MPa clean air source to the pneumatic actuator and valve positioner. The air filter regulator belongs to the pilot piston type pressure reducing valve. It consists of two parts: main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, valve clack, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the spring pressure, the diaphragm is used to sense the outlet pressure change, and the pilot valve is opened and closed to drive the piston to adjust the flow area of the main valve throttling part to realize the function of pressure reduction and stabilization. This product is mainly used in gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
