High performance butterfly valve product overview:

 
The double eccentric butterfly plate with spherical sealing surface and single flexible lip seal seat are adopted, which are suitable for occasions requiring reliable sealing and good adjustment characteristics. Due to the design of double eccentric butterfly plate, the valve has tight sealing performance and long service life. It can be used to cut off or adjust the flow quickly. The product is suitable for conveying liquid and gas (including steam) in various industrial pipelines. After special selection, it can also be used in special media, such as chlorine, oxygen, high vacuum, sulfur resistant or corrosive media. The product can also have fireproof structure for selection. The connection method can be double clamp type or lug type single flange design for large diameter and pipeline through terminal.
 
Because the butterfly valve of this product is designed based on the principle of three-dimensional eccentricity, the space movement track of the sealing surface is idealized, the sealing surfaces are free of friction and interference with each other, and the sealing materials are properly selected, so that the sealing, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve are reliably guaranteed.
 
The main features of high-performance butterfly valve are as follows:
 
1. Small opening torque, flexible and convenient, energy saving.
 
2. The three-dimensional core structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable and no leakage is achieved.
 
3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
