SMC VQ21A1-5YZ-C6-F Solenoid Valve 2 Way 2 Position

The SMC VQ21A1-5YZ-C6-F is a compact, pilot-operated 2-port, 2-position solenoid valve designed for dry air and inert gas service. In operation, a single solenoid shifts the valve to connect or vent a flow path, delivering on/off control of a downstream actuator in tight spaces. It is rated for 0.1–0.6 MPa supply pressure and provides a Cv of 0.39, suitable for moderate-speed actuation of small cylinders or pilot circuits. As part of SMC’s VQ20/30 family, this single-unit valve supports straightforward two-position control, commonly used in packaging equipment, laboratory automation benches, and other compact pneumatic installations where space is at a premium. The valve is designed for clean, dry gas service and is compatible with air and inert gases, making it a versatile choice for systems that require dependable operation in constrained environments.
