Characteristics

Double eccentric rubber structure, rubber seat with elasticity and more reliable sealing

Small size, light weight, low cost, easy to install, its advantages are more obvious in large caliber

Seat and seal are movable for easy maintenance and change

Large channel area and small flow resistance

Quick opening and closing, flexible operation, light and effortless

Adjust the tightness of the sealing ring to control the sealing compression to the best condition and longer service life
