Summary

Triple eccentric multi-level metal seal butterfly valve series products are long service life, energy-saving butterfly valve. Its adopts triple eccentric structure design, seat is built with hard and soft seal compatible multi-level structure, with advanced processing skills and technology. This product consists of valve body, disc, multi-layer valve seat, stem, transmission and other major components. So it is widely used in the metallurgical, electric, petroleum, chemical, air, gas, combustible gas and corrosive medium pipeline with temperature higher at 550 ℃. It is the best device to adjust the flow and cut off the fluid.

This butterfly valve is a triple eccentric designed one, the sealing surface space trajectory achieves idealized, Sealing surface without friction between each other, no interference. With choice of  proper sealing material, the butterfly valve sealing,
corrosion resistance, high temperature resistance and wear resistance are reliable.

Its main features are as follows:
1, open torque is small.
2, triple eccentric structure, so that the disc will close more and more tightly, its sealing performance is reliable, without leakage.
3, high pressure resistance, corrosion resistance, wear resistance, long life and so on.
