Compressor Solenoid Valves

Main Features

Aluminum Alloy Valve Body: High‑strength cast aluminum housing, light‑weight structure, good oil‑mist corrosion resistance, adapts to high‑pressure complex working environment of industrial compressors. Premium FKM sealing components resist oil aerosol erosion, low air leakage and long service life for oil‑mixed compressed‑air medium.

3/2‑Way Pilot‑operated Structure: Compact plate‑mount modular design, fast response, stable switching performance, anti‑clogging against oil‑aerosol impurities, suitable for frequent cyclic load‑unload operation.

Applications

Outputs control air pressure to actuate intake valve for loading; cuts control air and releases pressure for unloading and blow‑down venting. Stabilizes system pressure, prevents heavy‑load motor startup and protects compressor main unit.

Extended Application: Pneumatic directional control for other industrial pneumatic equipment with non‑corrosive compressed‑air medium.

Working Principle

De‑energized state: Solenoid stays default spring‑return position, control air exhausts, compressor keeps unloading state.

Energized state: Electromagnetic force drives pilot spool to switch air passage, outputs control air pressure to intake actuator, compressor switches to loaded operation.

De‑energized: Spring resets spool, control air discharges, compressor enters unloading and blow‑down cycle.
