Plastic Air Release Valve

WW-C30-P Combination PN16 Air Release Valve Threaded, AS4956 approved & WSAA

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.
