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:

. Advanced design: Simple mechanism and strong float to prevent cracking during sudden water hammer& quick closure.

.  Drain boss at the top & bottom for cleaning.

.  No arms or levers to prevent vibrating, bending, direct closure of the fl oat.
. Fully fusion epoxy coated inside and outside of valve body for long term services.
. Manufacturing standard : BS EN1074-4, AWWA C512
. Flange drilling and dimension : BS EN 1092 and BS EN 558 and ANSI flange.
