Double Eccentric Butterfly Valve Features:

1. When open, have large circulation area, low fluid resistance.

2. Bi-directional sealing & unidirectional sealing are available.

3. Simple construction, short Length pattern design, small and portable, easy for install, disassembly and assembly, maintenance, can installed in any position.

4. Sealing performance is good, generally rubber sealing surface for normal pressure and temperature. But metal sealing surface improve butterfly valve pressure and temperature.

5. Light weight is suitable for big size using conditions.

6. Suitable for high cycling frequencies.

7. Complete perfect sealing for zero leakage.

8. Could choose different parts materials, suitable for kinds of mediums.

9. Straight flow characteristics, perfect regulation performance.

10. Combined valve sealing and valve body as a whole, make the valve a longer life circle.

Generally speaking, double eccentric butterfly valve is widely used in big size pipeline for regulation. Because butterfly valve’s disc moves frictionally, it is mostly used with medium with with suspended solid particles. But according to the strength of sealing surface, also suitable for particles and powdery medium. Eccentric butterfly valve is applicable for flow regulation. Butterfly valve’s length and height is smaller than other type valves, open and close speed is fast, has good characteristics of fluid control. When need to control fluid in butterfly valve, the most important thing is to choose size and type of butterfly valve, to make work correctly & effectively. Double eccentric Butterfly Valve, generally used in petroleum, chemical, food, medicine, paper making, water, sea water and electricity, shipping, water supply and drainage, metallurgy, energy system, such as the system of pipeline. Double Eccentric Butterfly Valve consist of body, disc, shaft seat and drive actuator( lever, worm gear, pneumatic or electric actuator), through driving actuator to drive the shaft and disc rotation to achieve the opening and closing, control flowing.
