Product Description

High performance butterfly valve product overview:
Double eccentric butterfly plate with spherical sealing surface, with a single flexible lip sealing seat, suitable for the occasion requiring reliable sealing and good adjustment characteristics. Due to the design of the 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 the transportation of liquid and gas (including steam) in various industrial pipelines. Specially selected, can also be used for special media, such as chlorine gas, oxygen, high vacuum, sulfur or corrosive media. The product can also have a fireproof structure for choice. The connection method can be used for clamping or for large pipe diameter and pipe through the terminal of the lug type single flange design.
Because the butterfly valve of this product is designed by the three-dimensional eccentric principle, the space movement track of the sealing surface is idealized, there is no friction between the sealing surface, no interference, and the sealing material is selected properly, so that the sealing property, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve are reliably guaranteed.
The main characteristics of high performance butterfly valve 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 closer and tighter, its sealing performance is reliable, to achieve no leakage.
3, high pressure resistance, corrosion resistance, wear resistance, long service life, etc.
