Air Release Valves

Cla-Val Air Release and Combination Air Release Valves help protect fire protection systems from air lock and collapse by eliminating excess air or admitting air before a vacuum condition can occur. They not only help the system maintain its design capacity that could be impacted if entrained air is present in the pipeline, they are also critical to reliable and safe pump start-up and stopping operations.

Cla-Val air valves are available in a variety of configurations, end connections and materials to meet most any fire protection system application requirements.
