Product Description

R-71700 series high performance butterfly valve feature double eccentric design which the positioning of the valve shaft/disk connections cause the disk to take a slightly eccentric path on opening. This allows the disk to be swung out of contact with the seal as soon as it is opened. Thereby reducing friction and wear. Combine with the compensational seat design to prolong lifecycle with stable sealing performance.Good Shutoff and corrosion protection. Require minimum space for installation.
