C Type Combination Air Valve, 2" BSP AV0150B

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
