SMC VHS50-F06 Three Port Pneumatic Pressure Relief Valve

SMC VHS50-F06 is a three-port pneumatic pressure-relief valve in the VHS-D family, sized on the 50-body platform for compact installation in panel- or bracket-mounted relief circuits. It relieves excess pressure in pneumatic lines to protect actuators, cylinders, and other components from overpressure events while allowing normal operation to continue. The VHS50-F06 designation identifies the baseline three-port relief configuration within the VHS-D line; catalogs and distributors also reference a related VHS50-F06-M-D variant that adds mounting features and lists a 3/4 in size with locking holes for secure installation in industrial environments. The M-D variant is described as OSHA-standard-compliant in distributor listings. SMC literature and global component lists confirm the VHS-D family includes 3-port pressure-relief valves with mounting-locking-hole configurations in the VHS50 family. Typical applications span factory automation, pneumatic tooling, clamps, and other equipment where reliable overpressure protection is essential. When selecting among VHS-D 50-series relief valves, engineers consider mounting method, required relief characteristics, and connection size, with VHS50-F06 serving as the standard 3-port relief configuration in many automation installations.
