ROSS Controls 2773A4082 Lockout Valve

The ROSS Controls 2773A4082 is a 3‑way, 2‑position lockout valve from the L‑O‑X family that combines manual energy isolation with pilot control for pneumatic circuits. It features a 1/2‑inch NPT port size and a 120 VAC solenoid pilot, enabling remote energization of the pilot while the valve remains in a locked‑out state for maintenance. This valve is rated for 0 to 10 bar (0 to 150 psi) service, making it suitable for typical industrial pneumatic systems. Inline mounting and a dedicated lockout mechanism support OSHA‑compliant lockout/tagout directly at the machine, reducing the need to access main panels. In normal operation, the valve can route or block air flow depending on the lockout status, providing a safe, verifiable isolation point before maintenance begins. The combination of manual lockout control with solenoid pilot actuation allows controlled isolation sequences while enabling remote re‑energization when permissive, aligning with common safety practices in automated cells, presses, conveyors, and other equipment using pneumatic actuators. This model is one of the 27 Series piloted lockout valves designed for reliable energy isolation in industrial environments, offering robust construction and compatibility with the broader ROSS Controls LOX safety ecosystem.
