ODM Triple Function Air Release Valve For Water Line

Triple Orifice Air Valve Flange End

1. PRODUCT PROFILE

Triple function air release valve is installed at the pump outlet or in the water supply line to remove a large amount of air from the pipe or discharge a small amount of air collected at a higher level of pipeline into the atmosphere,so as to improve the efficiency of the pipeline and the pimp. The device evacuates great air amounts during the filling of the main, allows the inlet of great air amounts (in order to avoid a vacuum effect) during the emptying of the main and evacuates small air amounts that are accumulated in the high points of the main during normal working conditions.

2. FEATURES

· Discharge air more flexible

· Preventing of the water hammer

· Discharge the air slowly

· Safer self-protection

· Long service life

· High flow rate air discharge capacity for pipe-filling operation

· High flow rate air inlet for pipe drainage operation and in case of pipe burst

· Continuous evacuation of air under normal working conditions (small orifice function).
