combination air release vacuum valve

C Type is a high quality combination air valve for a variety of irrigation networks and operating conditions. With its advanced aerodynamic design, double orifice and Surge, it allows efficient release of air pockets from system during pipelines filling, also release a little air continously during pipeline pressurised and enables large volume air intake to avoid the vacuum formation in the event of network draining. Features: · Large Flow: Sֺtraight flow body with large diameter automatic orifice, more than usual flow rates. · Excellent Seal: Prevents leakage under low pressure (0.1bar /1.5psi) by dynamic sealing. · Less jetting: Reduces jetting water during automatic air release as the excellent intake and exhaust channel structure. · Anti-clogging: The outlet with backwash structure is not easy to accumulate dirt, which can be suitable for different water quality. · Reliable and durable: Produced by excellent raw material which is of corrosion, chemical and fertilizer resistant, less maintenance and longer service life. Application : · Mֺain Irrigation Networks: Protection against air accumulation and vacuum formation downstream of pumps, along supply lines and at high place in main irrigation networks. · Iֺrrigation Control Heads: Protection against air accumulation and vacuum formation at filtration, and fertilization stations and downstream of main control valves. · Iֺnfield Systems: Protection against air accumulation and vacuum formation near water meters and automatic regulators. · Pֺumping stations: Maximising pumping efficiency, priming capabilities and reducing the possibility of pressure surges during power stop
