Rubber Lined Carbon Steel Flange Electric Butterfly Valve, Large-Diameter Hydraulic Valve

Product Description

Product Overview:
The main features of flange butterfly valve are:
1. Compact and lightweight, easy to disassemble and repair, and can be installed in any position.
2. The structure is simple and compact, with low operating torque and quick opening of 90 ° rotation.
3. The flow characteristics tend towards a straight line, with good regulation performance.
4. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possible internal leakage points.
5. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and extends the service life of the valve. It can be opened and closed under pressure for more than 50000 times and still maintain zero leakage.
6. The sealing components are replaceable and the sealing is reliable, achieving bidirectional sealing.
7. Butterfly plates can be coated with coatings such as nylon or polytetrafluoroethylene according to user requirements.
8. This valve can be designed for flange connection and clamp connection.
9. The driving mode can be selected as manual, electric or pneumatic.
Flange butterfly valves are suitable for industries such as water supply and drainage, sewage, food, heating, gas, ships, hydropower, metallurgy, energy systems, and textiles, with temperatures ≤ 120 ºC or ≤ 150 ºC and nominal pressures ≤ 1.6MPa. They are particularly suitable for bi-directional sealing and valve body corrosion prone applications, as a medium for regulating flow and intercepting flow.
