Product Overview
The high-performance butterfly valve adopts the three-dimensional eccentric principle, which idealizes the spatial motion trajectory of the sealing surface. The sealing surfaces have no friction or interference with each other, and the sealing material selection is appropriate, which makes the sealing performance, corrosion resistance, high temperature resistance, and wear resistance of the butterfly valve reliable. Can be used for media such as chlorine, oxygen, high vacuum, sulfur resistant or corrosive media
Structural Features
High performance butterfly valves have good control characteristics, flow characteristic curves with proportional changes, a wide adjustment range, and can still be reliably sealed for control systems. Single flange butterfly valves can be used at any end of the pipeline terminal throughout the entire pressure and temperature range.
The main features of high-performance butterfly valves are: 1. Small opening torque, flexible and convenient, labor-saving and energy-saving. 2. The three-dimensional core structure has reliable sealing performance and achieves no leakage. 3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
