Product Overview
Brass butterfly valve can be used in food, medicine, chemical and other clean pipelines, industrial environmental protection, water treatment, high-rise buildings, water supply and drainage pipelines for opening and closing or regulating medium flow.
Structural Characteristics
The three-dimensional eccentric principle is adopted to make the space movement track of the sealing surface reach the ideal. The sealing surface has no friction between each other, nointerference, and the optimal configuration of the sealing material, so that the sealing, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve are guarantee dreliably.
Its main features are as follows:
- Small opening torque, flexible and convenient, energy saving.
- Three-dimensional core structure makes the butterfly plate more and more tight, and its sealing performance is reliable, so that there is no leakage.
- High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
