Double Eccentric

DVD Butterfly Valves have divided two-piece shaft that is guiding the disc. One of these shafts transfers the gearbox rotation force to the disc.

In case of an operation of the gearbox, the shaft rotates in its axis and moves the attached disc to open or close the valve.

The second shaft is used to guide the disc to the body of the valve. Friction of guiding is lowered by the bronze bearings on the body.

DVD Butterfly Valves have Closed End Disc Design, and shaft bearing system is isolated from the medium by o-rings. As a result, high corrosion resistance and durability is achieved.
