Overview
The Ross Y1523C4002 L-O-X energy isolation device is a manual 3/2-way lockout valve from the 15 Series / Classic line. Rated for pressures 0-20 BAR, this pneumatic safety valve is engineered for controlled manual isolation and exhausting of system pressure, making it essential for safe lockout and tagout (LOTO) procedures in pneumatic systems. The yellow body with large red handle provides clear visual identification and ergonomic control.
