Available with 1/4 and 3/8 in. ports, manual L-O-X valves control airflow and meet OSHA regulations, ANSI standards, European regulation EN 1037, and Canadian Standard CSA Z460. When handle is pulled outward, air moves freely. Short inward push of handle shuts off airflow and opens exhaust port to release downstream air. Equipped with Teflon seals, valves offer indicator port option for test point verification of absence of energy downstream.
