Key Specifications/Special Features:
- 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
- STL 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
- Lntrinsical fireproof property thanks to all metal structure and leak-tight performance
- 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
