SMC VHS40-03-R-X502 Industrial Pneumatic Solenoid Valve

SMC VHS40-03-R-X502 is a 3-port, 2-position valve from SMC's VHS40 family, configured as a lock-out hand valve with a built-in exhaust silencer (X502). The valve uses Rc 3/8 port connections and runs about 107 mm long, enabling compact integration in control panels. It is rated for a proof pressure up to +1.5 MPa, making it suitable for standard factory pneumatic circuits. In a 3-port, 2-position arrangement, it connects the supply to an actuator port while venting the exhaust, delivering reliable manual control of cylinders or grippers. The lock-out feature adds a mechanical override to safely de-energize the circuit for maintenance or safety procedures. The built-in silencer reduces discharge noise, helping meet workplace noise requirements. Common applications include automated manufacturing lines, packaging equipment, press and clamping stations, and other pneumatic control tasks where compact size and safe manual shut-off are important. As part of the VHS40 line, this model aligns with standard SMC porting and mounting conventions, enabling straightforward integration with compatible FRL components if needed.
