PROS Double-eccentric Butterfly Valve can reducing the mechanical abrasion and the extrusion corner travel during opening or closing .Because of the butterfly plate sealing face will break away from the valve seat sealing face completely, when the plate rotates from 0° to 8°-12°.
Main Features :
PROS Double-eccentric Butterfly Valve During the valve opening or closing, the butterfly plate sealing face will be deviated gradually from and pressed into gradually the valve seat sealing face, thus reducing the mechanical abrasion and damage between the butterfly plate and the valve seat during opening or closing.With the reduction of mechanical abrasion and extrusion, the sealing performance and service life of the butterfly valve will be improved greatly.
Design Features :
Light weight,maintenance friendly and long seevice life .
Can suited the small installation space;
Realiable sealing effect;
Compact and Simple Structure with small torque;
Flow adjusting is very good ;
