The ALC® is an in-line, spring assisted, single guided "wafer" check valve designed to prevent "water hammer" and "reverse" flow. The lightweight compact design fits between mating flanges and meets API 594 Face-to-Face dimensions. The ALC® is an easy to maintain check valve for applications involving liquids, gases or steam. Tapped holes are provided in the body for lifting lugs to assist with installation. (10" & larger only)

All temperature ratings are for standard valves.
