Product specifications: DN32-DN450
Product Features
Detailed introduction:

The DN32-DN450 split type centerline soft seal butterfly valve is a conventional butterfly valve preferred for pipelines, with a simple structure, low flow resistance coefficient, flow characteristics tending towards a straight line, and no debris retention. And it has the advantages of light weight, easy installation, and low driving torque. This type of valve can be used to cut off the medium and also to regulate the flow rate of the medium. The driving device can be manually, electrically, or pneumatically operated according to user requirements. By selecting parts made of different materials and using sealing rings made of different materials, it is possible to adapt to different media and working conditions, achieving optimal cost and performance.
Soft sealed 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 ℃ or ≤ 150 ℃ 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. Its main characteristics 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.
