SMC VHS50-10 Lockout Hand Valve 3 Port Pneumatic Valve

SMC VHS50-10 is a three-port, hand-operated lockout valve designed to isolate and vent pneumatic lines for maintenance, featuring a simple lever action and a built-in locking-hole design to accommodate padlocks in energy-isolation procedures. As part of the VHS50 family, it is a single-action, pressure-relief valve with locking holes that allow a padlock to secure the valve in the exhaust position, supporting energy-isolation procedures in industrial automation and reducing the risk of accidental re-energization. The unit provides an inlet, outlet and exhaust path and accepts common port-connection options (Rc, NPT, G) with sizes that vary by model; verify your exact thread and port size on the VHS50-10 variant, which is designed for safe maintenance while the rest of the system remains isolated. Typical operating pressure is up to 145 psi (1 MPa), enabling safe depressurization of downstream circuits when servicing equipment; some variants offer integrated residual-pressure relief to ensure immediate venting after isolation. Applications include lockout-tagout in compressed-air systems, machine safety maintenance, test bench setups, and any pneumatic line isolation where residual pressure must be released before servicing, with compatibility across common SMC control systems and modular FRLs.
