Both side seal, low torque, Dovetail, Online repairing, double eccentric butterfly valve
Features:
. The valve is made of DI body and DI disc.
. 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 150-350MM use flat disc, and DN 350-1200MM use arch shape
disc.
. Epoxy coated interior and exterior.
. Valve design meets EN 593, BS 5155, AWWA C504 & API 609
. Top flange connection meets ISO 5211-1982, and F/F meets
EN558-1&AWWA C504.

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
