Overview
The SMC VHS30-N03-RZ is a pneumatic 3-port lock out hand valve designed for manual control in pneumatic systems. This manual valve provides reliable isolation and air management for maintenance and operational control in industrial automation and manufacturing environments. As a VHS series product, it delivers simple, hands-on operation without reliance on electrical actuators.
Key Features
- 3-port configuration for flexible air flow control and isolation
- Manual hand valve operation for immediate, direct control
- Lock out capability to prevent accidental air supply in maintenance scenarios
- Compact and lightweight design suitable for space-constrained installations
- Compatible with standard pneumatic tubing and fittings
