EN12233 Non Slam Check Valve

Non Slam Check Valve For Fire Fighting System Anti Water Hammer

Fire Fighting Anti Water Hammer Non Slam Check Valve Ductile iron Low Head Loss

Description:

NSCV- Non Slam Check Valve is used as protection against reverse flow when power failure in areas where noise pollution or water hammering is a critical issue. It can provide not only quiet performance but also low head loss. The faster closing speed can decrease the reverse speed of water to minimize the water hammer.

Features:

·Extremely short stroke, quick close

·Diffuser design- lowest head loss and streamline flow

·Zero leakage of rubber disc seat

·Spring hidden on back side of disc prevent clogging

·Bronze bearing-long life service

·Disc will positively close before reverse flow, and maximize the closing speed up to 0.2 Sec.
· Installation can be vertical/horizontal/inclined.

·High strength ductile iron body used for durability and less weight.
·Advanced dynamic design of single body with diffuser provides streamline flow and assures lower head loss.
·Stainless steel spring hidden in the diffuser under protection while valve in operation.
·Comply with EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.

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
