The Bermad C30-AC is a triple function combination air valve with assisted closure feature (design of anti-slam function), designed to limit water hammer in the event of column separation.

The assisted closure feature controls air discharge to avoid air valves “slamming shut”, which in turn generates water hammer. Valves are typically used on pump discharge manifolds and along the pipeline at locations where there is a possibility of column separation.

The valves are fully approved for drinking water purposes and have certification to AS4956 & AS4020
