Ross Controls D1523C4002 Lockout And Exhaust Valve

Ross Controls D1523C4002 is a Series 15 manual Lockout L-O-X valve designed for energy isolation in pneumatic systems. This 3/2 valve is configured for a 1/2" port size (inlet/outlet) with 1/2" G (BSPP) threaded connections and a 3/4" exhaust port (G thread), providing a dedicated vent path to atmosphere when the valve is in the OFF position. The valve body is aluminum, the stainless-steel spool ensures durability, and fluorocarbon seals resist wear in typical industrial environments. The "C" sub-family code denotes Classic/High-Capacity construction within the Series 15 lineup, aligning with demand for reliable, repeatable lockout performance. As a manual Lockout L-O-X valve, it is designed to isolate compressed-air circuits during maintenance and safety interlocks, allowing a verified OFF condition while permitting exhaust flow to atmosphere through the exhaust port. Typical applications include packaging lines, automation cells, CNC tooling, and general manufacturing equipment where safety-focused energy isolation and controlled venting are required. With its BSPP threading, the D1523C4002 integrates with standard plant air systems and L-O-X safety assemblies to support compliant energy isolation cabinets and related safety procedures.
