Resilient Seated Gate Valve, Cap operated, FBE Coated, Non Rising Stem
NRS Resilient seated gate valve is a soft seal wedge to provide both side sealing function. The valve is designed with new technology for light operating. When the valve is fully opened, there will no clogging and no corrosion due to the full flow area.The rubber wedge has good resilient memory & long service life. It can be used extensively in all kinds of water supply & sewage, fire-fighting and function as an isolation valve.
Features:
• The material of Body & bonnet is high grade ductile Iron GJS500-7
• Disc is designed with an abrasion resistant nylon guide that can
help minimize opening or closing torgue and smooth during
operation.
1. EPDM fully vulcanized
2. WRAS approved
• Forged stem provide stronger stem operation and less moving
parts.
1. SS420 / 431
2. Platform provide better strength
• Disc is covered by high-grade rubber meet the standard of
drinking water.
• High-tech rubber curing with precise geometry dimensions, more
resilient & strong adhesive to ductile casting.
• The 4 O-ring stem seals are designed to prevent stem leakage. and
provide replacement of the O-ring without disassambling of valve
from mainline pipes.
• Inside & outside of the valve are coated with epoxy resin
powder.
• Manufacturing standard meets BS EN 1074-1, EN1074-2, BS 5163, BS
EN 1171.
•Face to Face Distence meets the following standard: BS EN558-1.
• Bolts are protected by silicon glue.

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
