The structure is designed with the principle of three dimensional centering, and the valve seat adopts a multi-layer structure with hard and soft sealing, which is exquisite in workmanship and advanced in technology. This product is composed of valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism and other main components. It is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage pipeline.

D673H Pneumatic Three Eccentric Hard Seal Butterfly Valve Product Characteristics
Because this product is used in valve design principle of three-dimensional space trajectory eccentric, the sealing surface of the sealing surface to achieve the ideal, no friction, no interference between each other, and the sealing material selection properly, so that the valve sealing performance, corrosion resistance, high temperature resistance and wear resistance has been a reliable guarantee. Its main features are as follows:

1, Small opening torque, flexible and convenient, labor-saving and energy saving.
2, Three dimensional core structure, so that the butterfly plate closes more tight, its sealing performance is reliable, to achieve no leakage.
3, High pressure resistance, corrosion resistance, wear resistance, long service life and so on.
