Sewage Combination Air Release Valve Single Chamber Triple Function Flange Type Full Flow Area
Description:
Sewage Combination air release valve provide 3 functions:
1. Large air release
1-1. During water filling the pipeline, float will stay at its original position. (open)
1-2. Let large air out of valve thru big nozzle.
2. Small air release
2-1.When the water level comes up to the top, float will be up to its close position and close the sealing arc- big orifice and small orifice.
2-2.The air (2% of solved air in water ) are continuously coming out from water and gather at the top of the valve.
2-3.The float will be driven down and let small pocket out thru small orifice.
2-4.The sealing arc will still be in close position until empty of water
3. Large air intake during draining of the pipeline.
3-1.Float will drop down when empty of pipeline.
3-2.Large air will come into the pipeline thru valve.
3-3.Preventing from collapse of pipeline and break vacuum.
3-4.Protect the sealing o-ring from clogging in the pipeline.
Features:
