SMC VHS50-06B Pressure Relief Valve 3 4 Inch Port Size

SMC VHS50-06B is a 3-port pressure relief valve (single-action) designed to isolate supplied pressure in a pneumatic system and vent downstream pressure for maintenance. It features a 3/4 in nominal port size and a die-cast aluminum body for durable, lightweight service in industrial environments. The valve operates over a pressure range of 0.1 to 1 MPa (roughly 14.5 to 145 psi), making it suitable for systems that require controlled relief to protect downstream components and enable safe servicing. Part of SMC’s VHS family of 3-port relief valves, it is designed for straightforward installation in line or manifold configurations and is commonly used to isolate system pressure in automation equipment, pneumatic cylinders, and other compressed-air tooling, while providing a safe vent path during maintenance cycles.
