Ross Controls 2773A8082 Pneumatic Valve 1-10 Bar

The Ross Controls 2773A8082W is a 27 Series Piloted Lockout Valve with L‑OX manual energy isolation, engineered to safely control and isolate the air supply in pneumatic systems while allowing remote electrical control to enable or disable flow when the lockout is not engaged. As part of the 27 Series, this valve uses a 3/2 poppet configuration and a cast aluminum body with Buna‑N seals, designed for rugged industrial environments, and it carries a 24 VDC coil (W suffix) for electrical actuation. The unit is rated for operating pressures from 1 to 10 bar (15 to 150 psig), enabling it to suit typical shop floor and aerospace/industrial air systems where safety interlocks are required to prevent machine startup during maintenance. Typical applications include safeguarding downstream pilots and actuators, guarding interlocks, and serving as a safety isolation point in circuits that require remote electrical control to reset or release the lockout. With its L‑OX energy isolation feature, the valve provides a clear and verifiable method to ensure air supply is secured during servicing, while still allowing controlled re‑energization when appropriate. This model is identified by the Y2773A8082W designation within Ross Controls’ 27 Series family, signifying a lockout valve intended for piloted valve assemblies and safety‑critical pneumatic circuits.
