The Bermad C30-P-IP is an air release valve, designed to only allow air to discharge.
The IP (inflow protection) function prevents any air ever entering the pipeline due to the external check valve being fitted.
These valves are used in suction lines for pumps, pipelines only requiring air discharge, and siphon pipelines.
The valves supplied in Australia are full certified for drinking water to approvals AS4956 & AS4020 and WSAA appraised
