    UV double Eccentric Butterfly valves with double offset design occurs from the centerline of the disc rotation being horizontally and vertically offset from the stainless steel body seat. Unlike traditional concentric AWWA butterfly valves, the double eccentric design offers a “non-rubbing”resilient seat that releases compression after only a few degrees of opening, which results in a longer lifespan and provides low operating torques. Each valve is equipped with a dual shaft design giving it inherently high flow characterizes over a one piece shaft. This results in considerable savings to the owner by lowering pumping and energy costs over the lifespan of the valve.Importantly, if the resilient seat ever needed adjustment or replacement, it can be achievedwith common tools in the field compared to epoxy filled seats that require special equipment orvulcanized/bonded seats that cannot be field adjusted or replaced.
