Butt-welding Butterfly Valves in Triple Eccentric Metal Sealing , API 609
PRODUCT INTRODUCTION
Triple Offset Butterfly Valve
Description
The Triple-eccentric design:shaft from the centerline of sealing surface to form the first eccentric;the shaft offsets from centerline of pipeline to form the second eccentric;and the scalene cone form the third eccentric.This design can make effectively use of the cam effect,and completely eliminate the friction between the seat and sealing surface in the 90°travel,preventing the valve fromleakage caused by the abrasion of the sealing face,and extend its service lifetime.
