Ductile Iron NSF 61 Swing Flex Check Valve 40 degree incline EPOXY Coated Nylon Reinforcement Disc
Description:
Rubber Disc Check Valve, is a totally covered by EPDM or NBR rubber with nylon reinforcement and that is good for reliable reverse flow prevention. It can be used both in clean water/sewage water. The disc made of CS plate, 304SS bar and nylon reinforcement.It is a 40 degree angle declined seat helping to close quickly and minimize the water hammer and slamming.
Features:
Simple design disc w/o movable components
Over 50,000 cycles operations
Powder coating for corrosion resistance
40 degree incline angle-lower stroke and reduce water hammer and slamming.
Simple design, few internal components and big top cover makes inner cleaning, parts replacement and maintenance easier.
Keep 100% full flow area, reduce head loss.
General Applications:
For general water supply, fire fighting,HVAC/ cooling & sewage
system.

Suzhou Alpine Flow Control Co., Ltd
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
Our Mission :
Be the market leader in Water Valve Flow Control
