R-71700 series of high-performance butterfly valve with double eccentric structure design. The center of the shaft is biased away from the center of the valve body structure and combined with the design of the arc sealing surface of the valve plate, the valve plate can be quickly separated from the sealing seat when opening to reduce the friction force of the sealing surface, and the valve plate has better sealing performance when it is closed . Center self-positioning seal seat design combined with a unique seat compensation seal, the seat wear to be effectively compensated, while reducing the sealing friction to the valve, the operating force is greatly reduced effectively improve the butterfly valve control accuracy . The series of butterfly valve seal life, excellent long-term sealing performance for the general corrosive gas liquid medium regulation and cut off use.
