Ross Controls 1523C5012 Pressure Relief Valve

Ross Controls Y1523C5012 is a 3/2 manual lockout and exhaust L-O-X valve in the 15 Series, designed for energy isolation in pneumatic lines. It provides a 3/4-inch port with NPT threads and a cast aluminum body, offering a CV of 8.26 for controlled downstream flow, making it well-suited for safety interlocks in factory automation and maintenance environments. The valve combines a manual Lockout actuation with an exhaust function to vent downstream air when the lockout is engaged, helping prevent unintended restart of equipment during servicing. This Classic 15 Series L-O-X valve is commonly used where simple, rugged energy isolation is required, and it integrates with standard air preparation components and remote pilot regulators if used in larger safety systems.
