SMC Corporation VQC2201-51 Pneumatic Solenoid Valve

SMC VQC2201-51 is a five-port, two-position, double-solenoid pneumatic valve in the VQC2000 family, designed for 24 V DC operation and rated for up to 0.7 MPa. It offers a Cv of 0.80, enabling reliable actuation of connected actuators without excessive pressure loss in typical small- to mid-size pneumatic circuits. The valve’s five ports are configured as P (supply), A and B (actuator work ports), and R1 and R2 (exhaust ports), supporting precise bidirectional control of a double-acting cylinder. Dual solenoids provide independent energization of each direction, which improves switching reliability and allows straightforward integration with standard control schemes, including PLCs. Intended for compact, modular automation applications, the VQC2201-51 balances a compact form factor with robust electrical and pneumatic performance, making it a suitable choice when a 24 V DC, five-port, two-position valve is required to direct compressed air in automated lines.
