Large Air Exhausting Combination Air Release Valve Stainless Steel 304 Interal Parts

 

 
 
Description:
 
AFC's air release valve conforms to International standard EN1074-4 and AWWA C515. 
Compared with other plant air valve, ours have not only large air exhausting and large air intake under invacuum,but also one more function of small air releasing. As we know normally there is 2% air in water system,our av does not stop small air venting untill all air in valve is completely released while the top seal arc in closed status. 
 
Our air valve is 100% full bore(inlet-outlet),simple components,valve body and bonnet, float,seal arc, guide barrel etc,most of them can be recycled-evironmental. Single valve chamber,unlike many connected bodies are easy to break up during transportation. All internal accessories are of AISI 304SS, hardness and quality are quaranteed.
 
There is a seal gasket in the valve above big float and it helps orifice make better sealing effect. With rubber seal gasket above float, it can absorb water hammar to avoid crash with seal arc and valve body and protect air valve from hurting.
 
Anti-shock accessories is available.
 

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.
