Overview
The Parker SV75-02 pneumatic safety lockout valve is a 3-port, 2-position shutoff device rated for pressures up to 300 PSI (20 bar). Designed for industrial pneumatic systems requiring controlled energy isolation, this lockout valve blocks air supply and vents downstream pressure simultaneously when engaged, enabling safe machine access during maintenance and repairs. The Parker SV75-02 features 1/4″ NPT threaded ports for inline installation and can be mounted directly in pneumatic circuits or integrated with modular air preparation systems.
Key Features
- Dual-Function Operation: Blocks inlet pressure and relieves downstream circuit pressure in single action for complete system isolation
- Padlock-Ready Design: Accepts standard single padlock or multi-worker safety locks; lockable in closed position only per OSHA requirement
- 300 PSI Maximum Rating: Rated for pressures up to 20 bar (300 psi), compatible with most industrial compressed air systems
- OSHA-Compliant: Conforms to OSHA Standard 29 CFR Part 1910.147 for pneumatic energy control during lockout/tagout procedures
- 1/4″ NPT Ports: Standard threaded connections allow use as standalone valve or integration with modular FRL components
- Simple Manual Control: Intuitive handle design enables fast engagement and verification of valve position
