Detailed Product Description
 
 
Combination Air Release Valve SS304 Internals Triple Function Full Flow Area Single Chamber

 

 

 

 

Combination air release valve provide 3 functions:

1. Large air release

2. Small air release

3. Large air intake during draining of the pipeline.

 

Float Sterngth:

 

• Max. float test
• DN 50-80 = 70 Bar
• DN 100-300=51 Bar

 

Features:

• All internal parts are 304SS material without rusting.

• 100% -full flow area thru the valve internal.
• Float with a rubber sealing on top, provide better sealing ( larger buoyancy ) effect on small orifice.
• 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.
• maximize the small orifice from 1.6MM (DN 50) to 4.0MM (DN300).
• Most parts of valves can be recycled.
• Single body preventing breakage of dual bodies connection.
• Screen on the top can prevent harm to children, insects and birds to get in.
• 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.

• 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.
