Compressor Solenoid Valves

Main Features

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

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

Applications

When the compressor stops unexpectedly, it rapidly cuts off oil passage to avoid lubricating oil flowing backward into air pipeline and air‑end, prevents oil flooding fault and protects compressor main unitAlibaba.

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

Working Principle

De‑energized state: Main valve stays closed, oil passage cut‑off.

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

De‑energized: Spring resets diaphragm, valve closes, oil supply is cut off for anti‑backflow protection.
