Features:
1. Centerline butterfly valve is compact in structure and light in weight, and easy for assemly and disassembly, and maintenance.
2. The operating torque of it is small.
3. It is small in flowing resistance and good in energy -saving effect, with discharge characteristic approximating inclined straight line.
4. It is featured by reliable sealing, zero leakage with ten thousands of opening and clising times.
5. The valve can be made of various materials, adapted to all kinds of media.
6. They are used in the pipelines and vessels for conveying various corrosive and non-corrosive fluid media in the engineering systems of water supply generating, petroleum, gas, chemicals, smelting, food, medicine, paper-making, shipping and environmental protection and also for regulating and cutting off the flowing of media.
