Resilent Seated NRS Gate Valve, Ductile iron, Fusion Bonded Epoxy Coated

Resilient seated gate valve is a soft seated wedge with fully encapsulated with rubber. The valve is designed by 3D software solidworks for light operating and weight. The FBE coating provides no corrosion for both interior and exterior. A good resilient memory & long service life by rubber wedge.

Newly advanced design, less operation torgue & abrasion resistance.

Features:

• Body & bonnet are made of high grade ductile Iron GJS500-7

• Disc is designed with an abrasion resistant nylon guide which can help less 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. Stainless Steel 420 / Stainless Steel 431 / Stainless 304/ Stainless Steel 316 are available.

2. Platform provide better strength

• Ductile Iron inside the wedge is covered by WRAS Approved EPDM which is suitalbe for 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.

• Both inside & outside are coated with epoxy powder.

• Manufacturing standard meets BS EN 1074-1, EN1074-2, BS 5163, BS EN 1171.

• F/F (Face to Face) meets the following standard: BS EN558-1.

• Bolts are protected by silicon glue.

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
