Manual rubber lined butterfly valve
Rubber lined butterfly valve is a special type of butterfly valve, with its disc installed in the diameter direction of the pipeline. In the cylindrical channel of the valve body, the disc-shaped butterfly plate rotates around the axis of the valve stem, with a rotation angle range of 0 ° to 90 °. When the butterfly plate rotates to 90 °, the valve is fully open. Rubber lined butterfly valves usually need to be installed horizontally in pipelines to ensure their normal operation. The rubber lined butterfly valve adopts a PTFE lined butterfly valve disc with a spherical sealing surface. The valve is easy to operate, has tight sealing performance, and has a long service life; Can be used to quickly cut off or adjust flow. Suitable for occasions that require reliable sealing and good adjustment characteristics. The valve body adopts a split type design, and the sealing at both ends of the valve shaft is controlled by adding fluororubber to the rotating base surface between the butterfly plate and the valve seat; Ensure that the valve shaft does not come into contact with the fluid medium inside the chamber. Widely applicable to the transportation of liquids and gases (including vapors) in various types of industrial pipelines, and in applications with highly corrosive media such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, aqua regia, etc. Characteristics of lined rubber butterfly valve 1. Novel and reasonable design, unique structure, lightweight, and quick opening and closing. 2. Small operating torque, easy to operate, labor-saving and agile. 3. Can be installed in any position, easy to maintain. 4. The seals can be replaced, and the sealing performance is reliable, achieving bi-directional sealing with zero leakage. 5. The sealing material has the characteristics of aging resistance, corrosion resistance, and long service life.
