Double Eccentric Butterfly Valve Dovetail Blue Rubber Seal Low Operating Torque

Doubel Eccentric Butterfly Valve with both side seal, low torque, Dovetail, repairing online

Features:

The disc of the BV DN100-DN500mm is flat shape, which allows bigger rubbish to flow through. DN500 to DN1200mm discs are arch shape with stronger ribs on the back, causing less compression and wearing of seal rubber to increase the life of rubber seal.At the same time water head loss can be reduced a lot and turbulence can be minimized,thus lowering the pumping cost and flow through disc energy is saved.

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
