The SMC VH321-N03 is a 3-port pneumatic hand valve that manually directs compressed air flow in industrial circuits. Rated for a maximum operating pressure of 1.0 MPa, it uses 3/8 inch NPT ports and provides three distinct positions for supply, exhaust, or blocked flow. This valve mounts directly into piping and serves as a simple on-off or directional control component in pneumatic systems without requiring electrical power or additional actuators.
