Double Orifice Air Valve Flange End
1. PRODUCT PROFILE
Double orifice air valve is one normal type of exhaust valve in the long big piping transport, which is normally mounted on the top of the pipe or pipe air holding place to discharge the air in the pipe, When the power supply for the pump is off, pump is stopped working, there will be negative pressure inside of pipeline, there will be vibration or break happened. Then, the air valve will work to suck into air quickly, keep the pressure inside the pipeline to be safe, making sure the pipe work normally. Prosper Flow combined air valve can remove the air existed in the pipe more flexible, preventing of the pressure fluctuation or other damages in the piping system. Double orifice air valve is applicable especially to the main water pipes and deep well pumps piping system.

2. FEATURES
· Discharge air more flexible
· Preventing of the water hammer
· Discharge the air slowly
· Safer self-protection
· Long service life
·Ductile Iron Body, flanged connection according to EN 1092-2. Float part made of polyethylene which can be replaced easily.
·While emptying the line, if the air intake amount less than the water discharge amount, pipe will face the danger of vacuuming. ·Regardless of the pipe type, vacuum force will pull the pipe perimeter to the center, hence contractions and bendings occur on the pipe.
·Gasket fixings become loose and casues leakage after filling. Welding and connection areas will be under same danger.
