The Bermad C50-SP is a triple function combination air valve fitted with surge protection designed for irrigation systems using treated sewage, or raw water with solids present, that can typically block conventional air release valves.

The unique low-pressure sealing function of the valve (0.5M)—combined with surge protection on the outlet—reduces the risk of water discharge  under operating conditions.
