Overview
The SMC VHS30-N03-Z is a manual pneumatic lockout valve designed for safe system isolation and pressure relief in compressed air applications. This 3-port valve operates across a 15–150 PSI range and features NPT-threaded ports for straightforward integration into existing pneumatic systems. Built with an aluminum die-cast body and lockable handle, it provides positive shut-off control essential for maintenance and safety procedures.
