Low Operation Torque Double Eccentric Butterfly Valve Disc With SS316 Sealing Ring FBE Coated

Double Eccentric Butterfly Valve Disc with SS316 sealing ring FBE Coated​ ​

Description:

AFC's Double Eccentric Flange Butterfly Valve is with advanced design. With dovetail seal design with multiple raised ring and internal epoxy fixing, it provides more space for rubber extension and brings much less compression and wearing between disc and soft seat and prevents the seal to be pushed out.

With double eccentric design and soft rubber seal on the body, the operational toque is one of the lowest among all the butterfly valves and can be sealed in both directions,disc and stem are very strong without any deformation.

Using tangent pin to fasten between stem and disc gives higher strength to pin,no gap between pin and stem makes not easy to deform and no chance to leak from the disc and pin,the disc interchangeable as well

Feature:

. The valve is made of ductile iron.
. Advanced newly design with dovetail seal design and captured by epoxy on the back, with multiple raised ring to have more contact with disc but less friction during closure.
. The double eccentric design provides less contact area of seal with disc, and less stress at the open position of the disc.
. The disc design with arch shape and thru disc can provide better flow capacity, stronger and less weight
. The shaft and disc connection with tangential pin which can be exchangeable and provide
rigid connection.
. The DN 100-500MM use flat disc, and DN 600-1200MM use arch shape disc.
. Epoxy coated.
. Valve design meets or exceeds EN 593.
. Top flange connection meets ISO 5211-1982, and F/F meets EN 558-1 series 13 & 14.

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
