(A20)2 Inch Drip Irrigation Pipeline Plastic Air Release Kinetic Valve

HOW IT WORKS

When filtration system is under pressure:

When the filtration system works under pressure, air will be gathered at the bottom of chamber, then the float will move up to seal the inlet.

When filtration system is in empty status:

When the system or pipe is drained empty, negative pressure will be formed in the air valve. Meanwhile the float moves down to take in air against vacuum formation.
