36WW Series
Wastewater Combination Air Valve
The Cla-Val 36WW SeriesCombination Air and Vacuum Valve is a multipurpose valve that combines the operation of both the 34WW Air Release Valve and 35WW Air and Vacuum Valve, especially for sewage and wastewater applications. It functions to exhaust large quantities of air in the pipeline during the filling cycle and to admit air, as necessary, to prevent a potentially dangerous vacuum from forming when being emptied either intentionally or as a result of pipeline breakage.
