SMC VXF21AAGB Solenoid Valve

SMC VXF21AAGB is a 2-port, direct-operated solenoid valve in the VXF2 series, designed for dust-collection and other pneumatic lines. It is normally closed (NC) and powered by a 24 V DC coil; energizing the coil opens the flow path between inlet and outlet. The valve uses 3/4 in port connections and features a 22 mm orifice size for the main passage, enabling reliable air control in compact piping configurations. As a direct piping type, the VXF21AAGB fits inline on 2‑port dust-collection circuits and similar pneumatic circuits where swift actuation and a small footprint are important. Typical applications include dust collection systems in manufacturing and material-handling environments, where two-way air routing is controlled by a single valve. This model is part of SMC’s VXF2 family, which provides valve options tailored to different ductwork and installation needs, all sharing direct-operated operation, a robust 24 V DC coil, and the NC/opening behavior that researchers and technicians rely on for automated air control. Energize the 24 V coil to open the valve and allow compressed air to pass through the 3/4 in ports, then de-energize to return to a sealed, closed state.
