a, fluorine-butterfly cut-off Industrial Valves features of cut-off valve is driven by the stem and axial movement up and down in the seat of the valve. It is mainly used to connect or cut off the pipeline of medium, but cannot be used for throttling. 我。 Globe valve the basic structure of 1. Fluorine plastic lined with J41F46 all pass-through, J45F46 dc, J44F46 Angle Industrial Valves with compact structure, flexible open and close, the corrosion resistance is strong, short stroke ( Average nominal diameter 1 4 or less) Etc, and in petroleum, chemical industry are widely used as to cut off the medium in the pipe system such as, but should emphasize that the fluorine plastic lining globe Industrial Valves is strictly forbidden, is by the flow control. In order to avoid the high speed medium erosion damage on throttle valve seal face. 2. Disc and stem are designed to prevent the pipeline pressure fluctuations and make the body inside the possibility of flushing, compact structure, the use of safe. 2. Design specification: follow GB / 12233 GB 12235 standard. 3. Manual, gear drive, pneumatic ( Open or closed) , electric.
