Products Details

D671F46 stainless steel fluorine lined butterfly valve

The valve is easy to operate, tightly sealed, and has a long service life; it can be used to quickly cut off or adjust the flow. It is suitable for occasions requiring reliable sealing and good adjustment characteristics. The valve body adopts a 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; to ensure that the valve shaft does not contact the fluid medium in the cavity. Pneumatic wafer-type fluorine-lined butterfly valve is widely used in the transportation of liquid and gas (including steam) in various types of industrial pipelines, and the use of severe corrosive media, such as sulfuric acid, phosphoric acid, strong alkali, aqua regia, etc. Corrosive medium.



Features:
1. Novel and reasonable design, unique structure, light weight, and rapid opening and closing.
2. Small operating torque, convenient operation, labor-saving and dexterous.
3. It can be installed in any position, and the maintenance is convenient.
4. The seals can be replaced, and the sealing performance is reliable to achieve two-way sealing with zero leakage.
5. The sealing material is resistant to aging, corrosion, and has a long service life.


Product advantages:
1. Geared double pistons, large output torque and small volume.
2. The cylinder is made of aluminum gold material, which is light in weight and beautiful in appearance.
3. Manual operating mechanism can be installed on the top and bottom.
4. The rack-and-pinion connection can adjust the opening angle and rated flow.
5. The actuator can be equipped with electrical signal feedback instructions and various accessories to realize automatic operation.
6. IS05211 standard connection provides convenience for product installation and replacement.
7. The joint screws adjusted at both ends can make the standard product have an adjustable range of ±4° between 0° and 90°. Ensure the synchronization accuracy with the valve.
