Performance
Butterfly valve adopts the three-dimensional eccentric principle design, the spatial movement trajectory of the sealing surface is idealized. There is no friction and interference between the sealing surfaces, and the sealing material is properly selected, so that the sealing and corrosion resistance of the butterfly valve, High temperature resistance and wear resistance have been reliably guaranteed. Its main features are as follows:
1. The opening torque is small, flexible and convenient, saving energy and energy.
2. The three-dimensional braided structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable, achieving no leakage.
3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.

Application
It is widely used in pipelines with corrosive media such as metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage.
