Double Eccentric Butterfly Valve

FONT

May 19,2022

Double eccentric valves are well known for their strength and resistance even at high pressure.
The basic principle of an eccentric design is to not align the axis of rotation of the disc with the centerline of the seat area, thus circumferential seal is moved away from the seat minimizing the stress when the valve opens. The disc will only be in contact during the first few degrees of valve opening and thereafter no contact and hence no friction. This design leads to minimal wear and low operating torques. Double eccentric butterfly valve used for regulation and flow sectioning in water supply facilities, plumbing, irrigation, etc. It has low head loss due to a hydrodynamic design of the disc, it is 100% water tight and need no gaskets to be installed.
