1. The elastic metal steel sandwich seal enables the valve to have zero leakage performance.

2. The frictionless design of right Angle rotation is realized by a unique three eccentricity principle. There is no friction between the 0-90 degree stroke seat and the butterfly plate seal ring, which eliminates the possibility of wear and leakage and prolonging the service life of the valve.

3. Torque seal can ensure the two-way zero leakage in the long-term operation of the valve, the valve switching life can reach 500,000 times.

4. All-metal structure + zero leakage performance, so that the valve has the essence of fire safety characteristics.

5. Butterfly valve adopts precision casting process, including the valve body and valve plate, this valve process has many advantages compared with the steel plate rolling process, the most important is the overall strength of the valve, relatively speaking, the cost of the valve is higher than the rolling process.

6. External stopper blowout stem is safe and reliable, in accordance with API 609 regulations.

7. Various packing structure forms to meet the requirements of different working conditions.
