Combination Air Release Valve Meet EN1074-4 Single Chamber Triple Function

Anti shock Triple Function Combination Air Release Valve Single Body ​

Features:

Combination air release valve with anti-shock function can help to prevent water hammer. It decreased the water velocity and restrict the velocity of air flow. This kind of valve is widely used in long water transmission pipeline where may occur a water hammer. If the air exhaust out the valve too quick, the water will comes in very fast, too. The water will prevent the float go up which caused the valve leaking.

AFC's air release valve conforms to International standard EN1074-4 and AWWA C512.

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.

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.

Alpine Flow Control (SuZhou) Co.,Ltd with major focus in the water valve design and manufacturing. The Management staff have over 30 years experience in the water valve design and manufacturing, combined with the high-tech electronics manufacturing experience of multi-national listed companies. This unique combination of traditional and high-tech industry management experience and skills have given us an advantage over the traditional valve manufacturer. More than 40% of our staff are technical staff with knowledge and experience in valve and mechanical design/manufacturing...

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
