1. Compact and lightweight, easy to disassemble and maintain, and can be installed at any location.
2. Simple and compact structure, low operating torque, and rapid 90 ° rotation opening.
3. Flow characteristics tend to be linear, with good regulation performance
4. The connection between the butterfly plate and the valve rod adopts a pin free structure to overcome possible internal leakage points.
5. The outer circle of the butterfly plate adopts a spherical shape, improving the sealing performance and extending the service life of the valve. It still maintains zero leakage when opened and closed under pressure for more than 50000 times.
6. The sealing element can be replaced, and the sealing is reliable and achieves two-way sealing.
7. Butterfly plates can be coated according to user requirements, such as nylon or polytetrafluoroethylene.
8. The valve can be designed for flange connection and wafer connection.
9. The driving mode can be manual, electric, or pneumatic.
Flange butterfly valves are suitable for industries such as water supply and drainage, sewage, food, heating, gas, shipbuilding, hydropower, metallurgy, energy systems, and light textile with temperatures ≤ 120 ℃ or ≤ 150 ℃, and nominal pressures ≤ 1.6MPa. They are particularly suitable for two-way sealing and valve body corrosion prone situations, as flow regulation and interception media.
