Ross Controls 1523A4102 Valve

Ross Controls 1523A4102 Valve is a 15 Series L-O-X energy-isolation lockout valve with EEZ-ON specifications, designed for safe maintenance of pneumatic systems. It is a 3-way, 2-position (3/2) valve in the modular A-sub-family, with a 1/2-inch port size indicated by the 4102 code. The valve body is typically yellow with a blue control handle for quick visual identification in busy industrial environments. As a lockout valve, it supports OSHA-compliant energy isolation during service operations, preventing re-energization until the lockout is removed. The 15 Series L-O-X family is designed to integrate with Ross energy-isolation systems, providing reliable manual shut-off control in automation installations. In the model number, the 4 denotes 1/2" port size and the suffixes (e.g., 02, 03, 12, 13) denote specific configuration and exhaust options; exact details should be confirmed in the official Ross catalog for this exact variant. Typical applications include isolating the air supply to presses, conveyors, and other pneumatic equipment during maintenance or setup changes.
