SMC VHS50-10A Three Port Pressure Relief Valve

SMC VHS50-10A is a three-port pressure relief valve (IN, OUT, EXH) in SMC’s VHS50 family, engineered to vent excess pressure from pneumatic circuits when residual pressure threatens equipment or safety. The valve is designed as a single-action relief device with locking holes for secure mounting to panels or manifolds, a configuration widely used in automation and material handling where tamper-resistant installation is important. Variants in the VHS50-10A family include versions with alternate mounting and connection options such as VHS50-10A-S and VHS50-10A-B-X1, reflecting the same three-port, single-action relief principle across assemblies. The VHS50 series commonly features a die-cast aluminum body, which provides rigidity and light weight for industrial environments. This model is widely cataloged by SMC and distributors, indicating its role as a compact, serviceable relief valve for systems requiring controlled release of pressure at or near operating pressure ranges, without the need for external actuation.
