Product Introduction

Triple eccentric multi-layer metal hard seal butterfly valve series products are long-life, energy-saving butterfly valves. Its structure adopts three-dimensional eccentric design, and the valve seat adopts a multi-level structure compatible with hard and soft seal, with advanced technology and exquisite processing. This product is composed of valve body, disc, multi-layer valve seat, valve stem, transmission mechanism and other main components.

Product Feature

Because the butterfly valve of this product is designed by the principle of three-dimensional eccentric, the spatial trajectory of the sealing surface can be idealized. There is no friction and interference between the sealing surfaces. And due to the optimized configuration of the sealing material, the sealing performance, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve can be guaranteed. Its main features are as follows:

1.Small opening torque, flexible and convenient, labor-saving and energy-saving.

2. The three-dimensional eccentric structure makes the disc tighter, and its sealing performance is reliable, achieving no leakage.

3. High pressure resistance and corrosion resistance. Wear resistance, long service life, etc.

TYPICAL APPLICATIONS

Triple eccentric multi-layer metal hard-sealed butterfly valve is widely used in metallurgy, electric power, petrochemical, air, gas, and water supply and drainage medium pipelines with medium temperature ≤ 650 ° C. It is used to adjust flow and cut off fluid. The sealing performance is reliable. The direction of extension and development of general-purpose butterfly valves to medium-pressure and medium-high temperature fields.
