Compressor Solenoid Valves

Main Features

Brass Valve Body: Heavy‑duty brass alloy housing, excellent high‑temperature and oil‑corrosion resistance, adapts to high‑temperature lubricating‑oil loop environment of large‑power compressors.

Pilot‑assisted Diaphragm Structure: Large flow capacity, stable opening‑closing performance, anti‑clogging against oil impurities, suitable for heavy‑duty continuous industrial operation.

Industrial‑grade Coil: AC110V 50‑60Hz, fast response, good shock‑proof and dust‑proof performance, reliable for heavy‑load workshop conditions.

Applications

When compressor stops, it quickly cuts off oil passage to avoid lubricating oil back‑flow into air‑end and air piping, prevents oil flooding fault and protects compressor main unit.

Working Principle

De‑energized state: Main valve stays closed, oil passage cut‑off for anti‑backflow protection.

Energized state: Electromagnetic force drives pilot diaphragm to open main valve port, oil circuit turns on for normal lubricating oil supply.

De‑energized: Spring resets diaphragm, valve closes, oil supply is shut off.
