Bermad C30 is a high-quality combination air valve suited for a variety of water networks and operating conditions. It evacuates air during pipeline filling, allows the efficient release of air pockets from pressurised pipes, and enables large volume air intake in the event of network draining.

With its advanced aerodynamic design, this double orifice valve provides excellent protection against air accumulation and prevents vacuum formation, with improved sealing in low pressure.

Options available on 50mm valves are surge protection or inflow protection kits.

The valves supplied in Australia are full certified for drinking water to approval AS4956 & AS4020 and WSAA Appraised & MRWA
