SMC Corporation VHS3500-03-X116 Lockout Valve

The SMC VHS3500-03-X116 Lockout Valve is a three-port pneumatic lockout device in SMC’s VHS family, designed to provide a dedicated isolation point in compressed-air lines for maintenance work. The X116 suffix denotes built-in locking holes that accept standard padlocks, allowing crews to lock the valve in a safe position and prevent unintended actuation during service. When used in a lockout procedure, SMC recommends a padlock with a shackle diameter of 5 mm or larger to ensure secure engagement. This model combines straightforward manual operation with a robust safety feature, making it suitable for industrial automation environments where reliable lockout is required to comply with safety procedures. As the specific VHS3500-03-X116 variant, it is distinguished from other VHS configurations that use different port counts or locking arrangements, yet shares the same family characteristics of padlock-ready isolation within pneumatic circuits. Typical applications include maintenance of pneumatic actuators and controls in manufacturing lines where a verifiable lockout point is required to meet safety protocols.
