OSHA-compliant L-O-X (lockout and exhaust) valves feature 14- and 38-in. port sizes. Valve is open when handle is pulled outward and air moves freely from inlet to outlet port. Short inward push of handle shuts off airflow and opens exhaust port to release downstream air. They are easy to operate, can only be locked in off position that blocks supply and exhausts downstream air, have full-sized exhaust port for quick air exhaust, and verify downstream air has been removed.
