Fusion Bonded Epoxy Coated Sewage Air Release Valve Spill Free

Spill Free Fushion Bonded Epoxy CoatedSewage Air Release Valve For Wastewater System

Functions:

Combination kinetic air release valve provide 3 functions:

1. Large air release

1-1. When filling the pipeline, float will stay at its original position. (open)

1-2. Let large air out of valve thru big nozzle.

2. Small air release

2-1. When the water level close to the top, float will be up to its close position and close the sealing arc- big orifice and small orifice.

2-2. The air (2% of solved air in water ) are continuously coming out from water and gather at the top of the valve.

2-3. The float will be driven down and let small pocket out thru small orifice.

2-4. The sealing arc will still be in close position until empty of water

3. Large air intake during draining of the pipeline.

3-1. Float will drop down when pipeline is empty.

3-2. Large air will come into the pipeline thru valve.

3-3. Preventing from collapse of pipeline and break vacuum.

3-4. Protect the sealing o-ring from clogging in the pipeline.

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
