Butterfly Valve Characteristic:

1. Elastic property of composite metal sealing ring to perform zero leakage.
2. Torque seal to ensure persisitent two-way zero leakage.
3. 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.
4. FUV one-piece hard-surface seat may adapt to many working conditions, which is featured by long service life and easy maintemance.
5. One-piece cast body, face-to-face dimensions conforming to ISO5752, ASME B16.10 and API609, replacement to high performance fireproof property thanks to all metal structure and leak-tight performance.

6. Anti-blowout stem for high dependability, completely conforming to API609.

7. The valve position indicator on the stem and the flange mounted at the top are in favor of the indication of disc position.

8. The stem of triple eccentric butterfly valve is a shaft, stem and disc are connected by key or pin-key combination.
