Features of flange type fluorine lined globe valve
1. J41f series fluorine lined globe valve refers to the valve whose closing part (disc) is driven by the stem and moves up and down along the center axis of the valve seat. It is mainly used to connect or cut off the medium in the pipe, but it can not be used for throttling. It has the characteristics of compact structure, flexible opening and closing, strong corrosion resistance and short stroke.
2. The disc and stem are designed as an integrated structure to prevent the possibility of the internals from rushing out of the valve body due to the fluctuation of pipeline pressure. The structure is compact and safe.
