ROSS Controls 2773A8811W Lockout Valve

ROSS Controls 2773A8811W is a 27-Series L-O-X piloted lockout valve designed for OSHA‑compliant energy isolation in pneumatic or hydraulic circuits. As a 3/2 poppet valve, it combines a manual lockout control with piloted actuation, enabling remote electrical or pneumatic control of energy isolation; the W suffix identifies a 24 VDC solenoid option for on/off control. In the 27-Series family, valves can be configured with remote electrical or pneumatic pilots, and port thread standards are typically NPT unless a D prefix indicates BSPP threads. This model is part of ROSS Controls’ L-O-X line, offering single‑point lockout to secure downstream equipment during maintenance or servicing. Exact valve size, flow characteristics, and port arrangement depend on the full model configuration, so verify the 2773A8811W specification for your installation.
