Elastic property of composite metal sealing ring to perform zero leakage
Torque seal to ensure persistent two-way zero leakage
The design of right-angled rotation with zero friction is implemented by the distinctive triple eccentric principle
It eliminates the friction between the seat and sealing ring in 90 rotation
One-piece hard-surface seat may adapt to many working conditions, which is featured by long service life and easy maintenance
One-piece cast (sheet welded) body, face-to-face dimensions conforming to ISO5752, ASMEB16.10 and API609, replacement to high performance butterfly valves and other types of valves, easy and flexible installation
Anti-blowout stem for high dependability, completely conforming to API609
The valve position indicator on the stem and the flange mounted at the top are in favor of the indication of disc position
The stem of triple eccentric butterfly valve is that a shaft, stem and disc are connected by of pin-key combination
