The Ross Controls Y2773A2072Z is a 27 Series L-O-X lockout valve with a solenoid pilot, designed to remotely control an air supply in safety-critical automation environments. This 3/2 pilot-operated valve is powered by 110–120 VAC (120V) and is intended for use with the L-O-X energy-isolation handle, allowing remote electrical control of the air line when the lockout handle is not engaged. It is commonly used in machine guarding and maintenance shutdowns to provide a safe, verifiable point of isolation in pneumatic systems. Ambient operating temperature ranges from 40 to 120 F (4 to 50 C).
