COMBINATION AIR VALVE Model C15 BERMAD C15 is a high quality combination air valve for a variety of water networks and operating conditions. It reliefs air during pipeline filling, allows 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, this valve provides excellent protection against air accumulation and vacuum formation, with improved sealing in low pressure conditions. Features & Benefits Typical Applications ֺ ֺ Straight flow body with large diameter automatic orifice: ֺ ֺ Main Irrigation Networks: Protection against air accumulation Higher than usual flow rates. ֺ ֺ Aerodynamic full-body kinetic shield: Prevents premature closing without disturbing air intake or discharge. ֺ ֺ Dynamic sealing: Prevents leakage under low pressure conditions (1.5 psi; 0.1 bar). and vacuum formation downstream of pumps, along supply lines and at elevations in main irrigation networks. ֺ ֺ Irrigation Control Heads: Protection against air accumulation and vacuum formation at filtration and fertilization stations and downstream of main control valves. ֺ ֺ Compact, simple and reliable structure whose parts are ֺ ֺ Infield Systems: Protection against air accumulation and ֺ ֺ Design in compliance with EN-1074 / 4 standard. ֺ ֺ Factory approval and Quality Control: Performance and ֺ ֺ Landscape Irrigation: Protection against air accumulation and fully corrosion, chemical and fertilizer resistant: Lower maintenance and increased life span. specification tested and measured with specialized test bench, including vacuum pressure conditions. ֺ ֺ Field proven designed for use in irrigation applications with water quality such as river water, channel water, dam water or treated effluent with high reliability.
