Detailed Product Description

 

 

EN1074-4 Triple Function Full Flow Area Single Chamber Combination Air Release Valve

 

 

 

Description:

 

Combination kinetic air release valve provide 3 functions:

 

1. Large air release

  1-1. During 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:

 

• 100% -full flow area thru the valve internal.
• maximize the small orifice from 1.6MM (DN 50) to 4.0MM (DN300).
• The float can resist high pressure from 51-70Bar for different size air valve.
• Guide barrel have few holes in surroundings for water exhausting and help float drop down easier and quicker during vacuum.
• Can blow off the water on top of the sealing arc thru small orifice and keep it dry to prevent polluted water coming into pipeline during vacuum.
• Most parts of valves can be recycled.
• Single body preventing breakage of dual bodies connection.
• All internal parts are 304SS material without rusting.
• Screen on the top can prevent harm to children, insects and birds to get in.
• Float with a rubber sealing on top, provide better sealing ( larger buoyancy ) effect on small orifice.
• Float with a rubber sealing can be as an absorber to prohibit water hammer direct acting on the sealing arc and seat impact.
•Special cover design-prevent stealing water.
