Large Air Exhausting Combination Air Release Valve Single Body Full Flow Area Triple Function
Description:
Air release valve of AFC meet International standard AWWA C515 and EN1074-4.
Our air release valve has an outstanding feature that our air
release valve has not only large air exhausting and large air
intake under invacuum,but also one more function of small air
releasing. As we all know , there is 2% air in water system,our air
release valve does not stop small air venting untill all air in
valve is totally released while the top seal arc is closed.
Our air valve is 100% full bore(inlet-outlet),simple components,bonnet and valve body , 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 test.
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.

Proven and supported by on-going quality and reliability test. AFC
has built it’s own in house reliability test laboratory to ensure
that our products not only meet the international quality and
reliability test specification such as the EN-1074-1/2 T-key and
R-key test, but also comply to various international valves
standards and specifications.
We already achieved WRAS certificate in 2011, and obtained FM
approval in early of 2012,
and UL for gate valve. Today, we have got many international famous
certificate for drinking water such as WRAS, NSF, AS, CE on certain
products, and our product range has expended to double eccentric
butterfly valve, rubber disc check valve ,non-slam check valve,
both clean water & sewage water air valve, hydraulic control
valve and penstock and we always focus on water system valves.
In 2018 year, our big plan is developing pressure management valves which has been proved to be a very helpful tool and economic way to save the leakage rate with limited investment and get a fast return in couple months and power savings
In addition, we have a special project team to focus on custom
design and special requirement
