A shut-off valve refers to a valve whose closing element (disc) is driven by the valve stem and moves up and down along the central axis of the valve seat. It is mainly used in pipelines to connect or cut off the medium in the pipeline, but cannot be used for throttling.

1. The basic series of globe valves are J41F46 straight through, J45F46 direct current, and J44 F46 angle globe valves. They have the advantages of compact structure, flexible opening and closing, strong corrosion resistance, and short stroke (usually 1/4 of the nominal diameter). They are widely used as cutoff media in pipeline systems such as petroleum and chemical industries. However, it should be emphasized that flow regulation is strictly prohibited for fluorine lined globe valves to prevent high-speed medium flow generated at the throttling port from damaging the sealing surface. The valve disc and valve stem are designed as an integrated structure to prevent the possibility of internal components flushing out of the valve body due to pipeline pressure fluctuations. The structure is compact and safe to use.

2. Valve manufacturing follows specifications:
