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.


· 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

C Type Combination Air Valve:

Air & Vacuum Relief Valve Family:


1. Main Irrigation Networks - Air relief and vacuum prevention downstream of pumps, along supply lines and at elevations in main irrigation networks.

2. Irrigation Control Heads - Air relief and vacuum prevention at filtration and fertilization stations.

3. High part of Irrigation Pipeline System - Air relief, Prevention of pipe broken as for high pressure air.


1. Pipeline Filling: During the filling process of a pipeline, high air flow is forced out through the kinetic orifice of the air valve. Once water enters the valve's chamber, the float buoyed upwards causes the kinetic orifice to close. The unique aerodynamic structure of the valve body and float ensures that the float cannot be closed before water reaches the valve.

2. Pipeline Draining: When a pipeline is drained, a negative differential pressure is created causing atmospheric air to push the float down.

3. Pressurized Operation: During pressurized operation the kinetic orifice remains closed.
