Rotary Butterfly Valve

Main Features:

1. Bi-directional flowing medium.

2. Double eccentric cam design.

3. Sealing pair: gradient functional materials such as martensitic stainless steel, austenitic stainless steel, cemented carbide, cermet, synthetic diamond and so on according to different hardness request.

4. Automatically alignment for range of working condition.

5. High quality sealing specific pressure, the high hard sealing pair can achieve zero leakage.

6. No friction between the sealing pairs: It has the characteristics of eccentric half ball valve, globe valve and wedge gate valve.

7. Small installation dimension & Small fluid resistance.

8. Its main structure is similar to butterfly valve, sealing type is similar to ball valve.

9. Range of Working temperature: 0℃~425℃.

10. Connecting type: Flange BW.

11. Range of application: Petroleum and petrochemical, metallurgy, chemical industry, electric power, gas, water conservancy, municipal administration, and construction industries, etc.
