New type AV02 Kinetic Air Valve into Chinadrip AIR VALVE family


Kinetic Air Valve

Kinetic Air Valve

Chinadrip AV02 air valve is a good quality kinetic air valve for irrigation networks & operating use. It evacuates air during pipeline filling and enables large volume air intake in the event of network draining.

With its advanced aerodynamic design and kinetic orifice, this valve provides excellent protection against vacuum formation, with improved sealing under low pressure conditions.

Typical Applications

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

·    Irrigation Control Heads – Air relief and vacuum prevention at filtration and fertilization stations.

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


Features & Benefits

Compact, simple and reliable structure

Straight flow body with large diameter orifice – High flow rates.

.Aerodynamic full-body kinetic shield – Prevents premature closing without disturbing air intake or discharge.

.Dynamic sealing – Prevents leakage during operation even under low pressure conditions (0.1 bar).

All parts are fully corrosion, chemical and fertilizer resistant – Lower maintenance and increased life span.

Principles of Operation

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.

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

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



Inlet sizes: 1” & 1-1/2”

Connections: Male Thread BSPT or NPT
