Anti Shock Spill Free Sewage Air Release Valve Prevent Water Hammer Available

EN1074-4 Anti-shock Waste Water Spill Free Sewage air release valve Ductile Iron​​

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

Function:

Combination kinetic air release valve provide 3 functions:

1. Large air release -

Anti shock device to prevent fast flow and water hammer. Decrease the air exhausting velocity to prevent water hammer. Slow down water and air out with multi holes on top sealing arc

2. Small air release

2-1.During operation the air produced by the pipeline is accumulated in the upper part. Little by little it is compressed and its volume increases, pushing the liquid level downwards and allowing the air release through the small nozzle.

3. Large air intake during draining of the pipeline.

During pipeline draining, or pipe bursts, it is necessary to bring in as much air as the quantity of outflowing liquid. This is to avoid negative pressure and serious damages to the pipeline and the entire system

Features:

. Spill Free.

. Drain boss at the top & bottom for cleaning.

For sewage water system.

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
