These Valves are installed on all high points of a system where it has been determined dual function Air/Vacuum and Air Release Valves are needed to vent and protect a pipeline. Generally, it is sound engineering practice to use (CAV) instead of simple purpose Air/Vacuum Valves. (CAV) are available in two body styles - (1) single body combination (2) custom built combination (CCAV) with two bodies.

The single body (CAV) is used where compactness is preferred. Immediate availability. Sizes 4" thru 24"
