Description

Summary

Elastic metal seal butterfly valve has a "U" type stainless steel seal ring, the precision elastic seal ring and polished disc three-dimensional eccentric contacted.

It solves the shortcomings of traditional eccentric butterfly valve sealing surface is still in sliding contact friction when the butterfly valve opens or closes in the range of 0 ° to 10 °.
The sealing surface is separated at the moment of disc opening, and seals when closure.  Therefore, it is widely applied to metallurgical, power, petroleum, chemical, air, gas, combustible gas and water supply and drainage and other corrosive media pipeline with temperature ≤550℃. it is the best device to adjust flow and cut off medium. main feature:

1, butterfly valve structure is simple, compact, light weight, easy to install and disassemble, easy maintenance;
2, butterfly valve with stainless steel "U" -ring, with a certain degree of flexibility Whether in the case of high temperature, low temperature, it has excellent sealing with the butterfly valve disc;
3, the eccentricity of the butterfly valve is adopted after strict calculation, "U" -type ring and butterfly valve disc almost have no friction. Long service life.
4, butterfly disc sealing surface uses cobalt-based hard alloy, sealing surface has the feature of wear resistance, long service life;
5, butterfly valve structure is unique. Opening and closing can be done by rotate stem at 90 °. Flexible operation, will not be affected by medium pressure, sealing is reliable.
6 has the features of high temperature resistance, low temperature resistance, corrosion resistance
