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.
