What is a flanged butterfly valve?
The flange butterfly valve is a type of butterfly valve, which refers to the butterfly valve connected to the flange connection. It is a very versatile valve, as well as another type of butterfly valve with a clamp connection. Compared with other types of valves, such as flange gate valve, flange globe valve and flange ball valve, flange butterfly valve structure is very simple, only flanged body, stem, disc, seat, driving device and so on a few parts. In addition, compared to other valves, the flange butterfly valve has a smaller size and lighter weight, which is more suitable for making large diameter valve. With the improvement of manufacturing technology, the flange butterfly valve can be used in more and more working conditions, not only can be used to adjust the flow, but also can be used to cut the flow, gradually began to replace the flange gate valve, globe valve, ball valve and other applications in the pipeline system.
Advantages of the flanged butterfly valve:
1.Electrostatic powder thermal spraying process valve body
Using electrostatic powder thermal spraying process, spraying thickness 250μm. Body heated at 200°C for 3 hours, powder cured at 180°C for 2 hours. After natural cooling, surface adhesion is 2 times higher than ordinary powder, more environmental protection.
2.PE heat shrinkable plastic packaging technology
Individually wrapped with heat shrinkable film and built-in desiccant. Isolation of air dust, easy storage and avoid moisture corrosion.
3.Good sealing performance
The seat adopts high specification ethylene propylene diene rubber, so that the rebounding and pulling force of the butterfly valve is stable and reliable, and there is no leakage of more than 10,000 times.
4.QT450-10 material
The body and disc are made of QT450-10 material, the ball rate is above 3, the mechanical properties are completely up to standard. The tensile strength is 450MPa, the extension rate is more than 10%, and it is not easy to break or freeze.
5.Solid valve body
The valve body is solid, the same caliber weight is heavier than other manufacturers.
