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
