Strength
1. The butterfly plate is driven by the valve stem. If it is rotated through 90°, it can be opened and closed once. By changing the deflection angle of the disc, the flow of the medium can be controlled.
2. Working conditions and medium: Butterfly valve is suitable for conveying various corrosive and non-corrosive fluids in engineering systems such as furnace, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation, building water supply and drainage, etc. On the pipe of the medium, used to regulate and cut off the flow of the medium.
