MOV321 mechanical valves provide direct-acting 3/2-way switching for compressed-air controls. G1/8 connections and a choice of roller, plunger and manual button actuators allow the valve to be selected for the required operating method.
The code combines MOV, the 32 three-port/two-position designation, connection code 1 for G1/8, and the actuator suffix. MOV321R is the roller-operated version.
