General Purpose 3/2 Solenoids

A 3/2 solenoid valve (three-way, two-position valve) is an electromechanical device designed to control the flow of fluids (air, gas, or liquid) by opening or closing different flow paths. These valves have three ports: Inlet (P) – The source of the fluid. Outlet (A) – The destination where the fluid is directed. Exhaust (R) – The venting port to release excess fluid or pressure. The two positions refer to the valve’s ability to either allow or block the flow between the ports. 3/2 solenoid valves are commonly used to control single-acting cylinders, pneumatic actuators, vacuum applications, and pressure release systems.
