SMC VEX3222-5DZ Pneumatic Solenoid Valve VEX Series

SMC VEX3222-5DZ is an internally piloted, 3-port, 3-position pneumatic solenoid valve in the VEX Series. This internal-pilot valve uses the VEX3222 solenoid to shift flow between the pressure port (P) and the work port (A) with the exhaust (R) returning air, delivering three discrete states in a compact, easy-to-integrate package. The configuration is a 3/3 valve with ports sized for small-diameter lines, typically accommodating 1/8" to 1/4" connections, making it suitable for space-constrained circuits and modular manifolds. The 5DZ designation identifies a 24 V DC coil variant within the VEX3 family, aligning with common industrial control voltages and enabling reliable, rapid actuation in automation and robotics applications. As part of SMC’s VEX Power Valve lineup, this model is designed for use in multiple-valve systems and can be paired with other VEX components (such as the external-pilot VEX3221) to support flexible control schemes, including compact automation tasks, pick-and-place tooling, and lightweight pneumatic control networks where precise three-position actuation is required.
