NON CLEAN, SEWAGE & WASTEWATER COMBINATION AIR VALVE Model C80 BERMAD C80 is a high quality combination air valve for a variety of sewage and wastewater networks and operating conditions. It evacuates air during pipeline filling, allows efficient release of air and gas pockets from pressurized pipes, and enables the intake of large volumes of air in the event of network draining. The elongated - body and lower float - is designed to reduce the contact between the fluid and the upper mechanism. With its advanced aerodynamic design, double orifice and Surge Protection device (optional), this valve provides excellent protection against air and gas accumulation and vacuum formation with improved sealing under low pressure conditions. C80 is designed to facilitate longer periods of operation without maintenance and it is easy to maintain. Features & Benefits Typical Applications ֺ Straight flow body with large diameter automatic orifice: ֺ Pumping stations: Air relief and vacuum prevention. ֺ Non Clean Water pipelines: Protection against air and gas Higher than usual air flow. ֺ Aerodynamic, full-body kinetic shield: Prevents premature closing without disturbing air intake or discharge. ֺ Dynamic Sealing: Prevents leakage under low pressure conditions (0.8 psi; 0.05 bar). ֺ Elongated body design: Prevents solids from making contact accumulation and vacuum formation at elevations, slope change points and road / river crossings. ֺ Wastewater Treatment plants: Air relief, protection against air and gas accumulation and vacuum formation. Compact, simple and reliable structure with fully corrosion-resistant internal parts: Lower maintenance and increased life span. ֺ The air valve can be opened from the top and the Protection (SP) or Inflow prevention (IP) devices. with valve’s operating parts. ֺ 2 Service ports and the addition of an optional drainage ֺ Two service ports: Enabling back flushing and drainage. ֺ Threaded Side outlet (3"; DN80) for connection of Surge ֺ Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions. Additional Features & Accessories ֺ Surge Protection (code SP): Smoother operation, preventing damage to the valve and the system. ֺ Inflow Prevention (code IP): Prevents intake of atmospheric air in cases where this could lead to damaged pumps, required re-priming, or disruption of siphon. ֺ Drainage Valve (code Z).
