Double Eccentric Butterfly Valve

“Eccentricity” can enhance valve performance
Double/triple 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

The first and most obvious benefit of this design is
-         High Performance
-         Minimal wear and guarantees a long service life.

Key words: valve,,Eccentric
