Compressor Solenoid Valves

Main Features

Brass Valve Body: High‑strength brass alloy housing, excellent high‑temperature and oil‑corrosion resistance, adapts to harsh compressor lubricating‑oil circuit environment.

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

Applications

When compressor shuts down, it rapidly 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.

Extended Application: Fluid on‑off control for other industrial systems with non‑corrosive lubricating oil medium.

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.
