Airtac GZ Globe Valve GZ30008J
1. Modular design with bracket compatibility for integration with G/GA series FRL units;
2. Configurable as manual three-way valve operation;
3. Visual confirmation of operational status through EXH./SUP. indicator markings;
4. OSHA-compliant safety mechanism: Features lockable actuator and integrated exhaust valve that simultaneously vents residual pressure while shutting off air supply during maintenance. This prevents accidental pressurization of downstream circuits by third-party interference, ensuring compliance with OSHA 29 CFR 1910.147 requirements for control of hazardous energy (lockout/tagout).
