Spill Free Triple Function Full Flow Area Single Chamber Sewage Combination Air Release Valve
Description:
AFC's sewage 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.
All internal accessories are of AISI SS316, 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.

1. Large air release
2. Small air release
3. Large air intake during draining of the pipeline.

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
