•  ARCK various types of air valves are used to solve the problem of air pressure inside the pipes of water supply systems and filtration systems. They adopt advanced aerodynamic design to ensure low pressure sealing, and large flow of exhaust and intake. There are three types of air valves to choose from: vacuum breaker, kinetic air valve, and combined air valve.

 These valves are applicable to all kinds of irrigation system. It evacuates air quickly during filling water to pipeline and withdraws massive air while water draining.

APPLICATION SCENARIOS：

• Pipe system - Protection against air accumulation in horizontal, ramp turning point and road/river crossings.
• Water supply system - Against air accumulation and vacuum formation.
• Near control valves and water metre - Increase the accury of meter and a better performance of control valves.
• Industrial and residential networks - Protection against air accumulation.

• When the pipeline is filled with water, the air valve discharges a large amount of air in the pipeline.
• When the pipeline is emptied, the air valve sucks in a large amount of air to prevent vacuum negative pressure.
• When the pipeline is under pressure, the intake and exhaust valves remain closed.

• Advanced aerodynamic design;
• Big inlet size allowing massive air flow;
• One- piece floating ball design ensure ontime shutting of outlet while the high speed airflow occurs;
• Quality sealing – prevents leakage under low pressure conditions (0.1 bar/1.5 psi);
• PP material with corrosion, acid, alkliane resistant features to be long lasting;
• Multi-installation size for various market demands;
