Overview
The SMC VHS30-N03-RZ pressure relief valve is a manually-operated 3-port valve engineered for residual pressure relief and isolation in pneumatic automation systems. Conforming to OSHA standards, this safety-measure manually operated valve can be used to prevent accidents caused by residual pressure in pneumatic lines. The valve provides simple, reliable operation without electrical components, making it ideal for both routine maintenance and emergency pressure venting applications.
Key Features
- Valve handle can be locked in position to prevent accidental operation
- Designed so that the supply and exhaust status of the air flow can be checked at a glance
- Body size 30, aluminum die-casted body construction
- Manual single-action operation with resin or metal handle options
- Simple assembly and maintenance reduces downtime
- Suitable for energy isolation and lock-out/tag-out (LOTO) procedures
