PVC butterfly valve is plastic butterfly valve. Plastic butterfly valve has strong corrosion resistance, wide application range, wear resistance, easy disassembly and easy maintenance. Applicable fluid: water, air, oil, corrosive chemical liquid. The valve body structure adopts the center line type. Classification of plastic butterfly valve: manual plastic butterfly valve, pneumatic plastic butterfly valve, electric plastic butterfly valve.
Plastic butterfly valve adopts PTFE lined butterfly plate with spherical sealing surface. The valve has the advantages of light operation, tight sealing performance and long service life. And can be used for quick cut-off or flow regulation. It is suitable for occasions requiring reliable sealing and good regulation characteristics. The valve body adopts the split type. And the sealing at both ends of the valve shaft is controlled by adding fluorine rubber to the rotating base surface between the butterfly plate and the valve seat. So as to ensure that the valve shaft does not contact with the fluid medium in the cavity.
It is widely used in the transportation of liquid and gas (including steam) in various types of industrial pipelines. And in the use of severely corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia and other highly corrosive media.
Plastic butterfly valve is used in many fields. The product performance of electric plastic butterfly valve is summarized as follows:
1. The valve body of plastic butterfly valve only needs the smallest installation space, and its working principle is simple and reliable.
2. Approximately equal percentage flow characteristics, which can use for regulation or on-off control
3. The valve body of the plastic butterfly valve is match with the standard raised face pipe flange.
4. The superior economic performance makes the butterfly valve the most widely used industry.
5. Plastic butterfly valve has a large flow capacity, and the pressure loss through the valve is very small.
6. The valve body of plastic butterfly valve has a very significant economy, especially the larger diameter butterfly valve.
7. Plastic butterfly valve is especially suitable for clean liquid and gas.
Features of PVC butterfly valve:
1. Compact and beautiful appearance.
2. The body is light and easy to install.
3. It has strong corrosion resistance and wide application range.
4. The material is sanitary and non-toxic.
5. Wear resistant, easy to disassemble, easy to maintain.
