SMC VFN21N-5DZ-02 Solenoid Valve

SMC VFN21N-5DZ-02 Solenoid Valve is an electromechanically actuated pneumatic valve from SMC designed to control compressed-air passages in control circuits. The valve uses a 24 VDC coil to energize the solenoid, enabling actuation for on/off airflow in automation and machinery environments. Model VFN21N-5DZ-02 identifies this specific configuration within SMC’s line, and the valve supports a supply-pressure range of 0.15 to 0.9 MPa (approximately 1.5–9 bar), indicating compatibility with typical factory air pressures. This information-oriented description focuses on the core electrical and pneumatic characteristics: brand (SMC), part number (VFN21N-5DZ-02), device type (solenoid valve), coil voltage (24 VDC), and operating pressure range. In use, it functions as a switch in pneumatic circuits, converting electrical control signals into controlled airflow without mechanical manual intervention. For purchasers, the model name and coil rating provide a straightforward basis for matching with compatible controllers and power supplies in standard automation setups.
