4/3 Explosion-Proof Solenoid Valve for Refrigeration

Introduction
This series of explosion-proof products are 3-position, 4-way solenoid valves manufactured with introduced foreign technology. They utilize a multi-port design controlled by four direct-acting solenoid operators. Functionally equivalent to two double-solenoid direct-acting 2-position, 3-way valves or four direct-acting 2-position, 2-way valves, these products feature compact dimensions, flexible operation, and long service life. They are widely used in fluid automation control systems and various environments.
