Butterfly Valves
Butterfly Valves
This product consists of valve body, disc, seal ring, transmission mechanism and other major components. Its structure is two-dimensional
or three-dimensional eccentric design，elastic sealing and hard and soft multi-level sealing compatible with the processing of new technology, so that the butterfly valve in
the operation of the work, reduce its torque, to achieve the efficacy of energy-saving.
This ensures the reliability of the butterfly valve as a whole in terms of corrosion resistance, high temperature resistance and abrasion resistance.
1、Unique structure, small and lightweight, flexible operation, labour-saving, convenient；
2、Reliable sealing, can meet the standards at all levels；
3、Good flow characteristics, and has the function of regulating；
4、Use of eccentric principle, so that the sealing surface approximate zero friction loss, extending the service life of the valve；
5、Wide range of applications, can be used for water, oil, gas and other industry；
6、Applicable to different temperatures and pressure levels below 6.4MPa, corrosion-resistant and other pipelines.
