COMBINATION AIR VALVE Model C35 BERMAD C35 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: ֺ ֺ Water networks: Protection against air accumulation and 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). ֺ ֺ Compact, simple and reliable structure whose parts are fully corrosion, chemical and fertilizer resistant: Lower maintenance and increased life span. ֺ ֺ Design in compliance with EN-1074 / 4 standard. ֺ ֺ Factory approval and Quality Control: Performance and 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. Additional Features & Accessories ֺ ֺ Service Port fitted with ¼”; DN6 plug (code P) ֺ ֺ Test point (code T) Inlet and Outlet Connection ֺ ֺ Inlets: male threaded 2”; DN50 ֺ ֺ Outlets: Sideways, 1.5”; DN40 female threaded Orifice Specifications Inlet Sizes Automatic Orifice Kinetic Orifice All images in this catalog are for illustration only vacuum formation at elevations, slope change points and road / river crossings. ֺ ֺ Body: Glass-reinforced Nylon ֺ ֺ Float Assembly: Polypropylene, Glass-reinforced Nylon. ֺ ֺ Elastomers: EPDM Operational Data ֺ ֺ Pressure Rating: 230 psi; ISO PN16 ֺ ֺ Minimum operating pressure: 1.5 psi; 0.1 bar ֺ ֺ Maximum operating pressure: 230 psi; 16 bar ֺ ֺ Media an
