BERMAD C30 is a high-quality combination air valve for a variety of water networks and operating conditions. It evacuates air during pipeline filling, allows the efficient release of air pockets from pressurized pipes, and enables large volume air intake in the event of network draining. With its advanced aerodynamic design, double orifice and Surge Protection device (optional), this valve provides excellent protection against air accumulation and prevents vacuum formation, with improved sealing in low-pressure conditions.
