SMC Corporation VEX3321-045MOZ Electro Pneumatic Solenoid Valve

SMC VEX3321-045MOZ is an external-pilot, 3-port, 3-position solenoid valve from SMC’s VEX3 power valve family. It provides directional control in compact pneumatic circuits by shifting the valve spool in response to an external pilot signal, enabling precise actuation of attached cylinders or pilot-operated devices. The VEX3 family includes an external-pilot variant (VEX3321) and an internal-pilot variant (VEX3322), offering flexibility in control topology for automation equipment. This model is designed for reliable, rapid actuation of pneumatic lines in compact machinery, supporting sequencing and pilot-operated circuit configurations. Exact electrical ratings, port sizes, mounting options, and response characteristics vary by model and are specified in the official SMC VEX3 product documentation for VEX3321-045MOZ.
