Product overview
Butterfly valve is a kind of valve that uses disc type opening and closing parts to turn back and forth about 90° to open, close or regulate the flow of medium. It not only has the advantages of simple structure, small volume, light weight, material consumption, small installation size, small driving torque, easy to operate, rapid, and can also have a good flow regulation and closing sealing characteristics, is one of the fastest growing valve varieties in recent years. Butterfly valve is easy to combine with various driving devices, has good durability and reliability. Its use in a wide range of fields, the use of varieties and the number of rising trend, and to high temperature, high pressure, large diameter, high sealing, long life, excellent regulating characteristics, as well as a multi-functional development of the valve, its reliability and other performance indicators have reached a high level.

1. Reasonable design, compact structure, easy to install and dismantle, convenient for maintenance.
2. Adopting eccentric structure, making full use of cam special effect, so as to realise that when the valve opens, the butterfly plate and the seat sealing ring are instantly detached, and the friction wear is eliminated on the 90-degree stroke.
3. Completely sealed, leakage is zero, whether in low or high temperature, sealing performance is stable and reliable.
4. Butterfly valve has metal hard seal and tetrafluoro soft seal two choices, suitable for a variety of working conditions and different media.
5. Adopting the whole shaft structure, the butterfly plate is truss structure, the butterfly plate has high strength, large overflow area, small flow resistance and energy saving. -
