Plastic Air Vlave
Applications:
The air valves play a major role in ensuring efficient and reliable operation of the irrigation system.
Air valves release air from the system, minimizing the pressure loss and admit air into the system, thus protecting the lines from collapse and preventing sand from being sucked into the driplines when the lines are drained.
There are 3 types of Valves:
- Air Discgarge and vacuum breaking Valve:
- At the inlet of a drip submain pipe:
– Preventing dirt suction into the driplines when lines are drained
– Discharging air from the submain pipe when lines are filled
- Automatic Air Valve:
– Releasing accumulated air in the outlet of buster pumps, filters and injection pumps
- Combination Air Valve
- At high points of the line and inclination changes
- After pumps
- At main and infield control heads
- Before and after isolating valves
- On gravel filtration systems
