J941F electric valve fluorine 
 A, J941F electric fluorine valve Overview 
 Pieces of cut-off valve is closed (valve) driven by the stem and do along the central axis of the valve seat down movement of the valve, mainly used in the pipe connected to the road or cut off the pipeline medium, but can not do with the throttle. 
 J941F electric valve fluorine basic structure: 
 1 fluorine plastic lining J41F46-type straight-through, J45F46 DC type, J44F46 Angle globe valve, with a compact, flexible, open and close, strong corrosion resistance, short stroke (typically nominal diameter 1 / 4) other items of advantages, is widely used in petroleum, chemical and other piping systems do cut the media to use, but needs to be emphasized is the fluorine plastic lining used as the cut-off valve flow control is prohibited, to avoid cutting the mouth of the high-speed media streaming erosion damage to the sealing surface. 
 2 disc and stem design as a whole structure, to prevent the pipeline pressure fluctuations within the body parts out the possibility of compact, safe to use.
