1Product Overview
A shut-off valve refers to a valve that 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.
Basic structural characteristics
1. Plastic lined J41 straight through, J45 straight through, and J44 angle globe valves have advantages such as tight structure, flexible opening and closing, strong corrosion resistance, and short stroke (usually 1/4 of nominal diameter). It is widely used as a cut-off medium in pipeline systems such as petroleum and chemical industries, but plastic lined globe valves are strictly prohibited from being used for flow regulation to prevent high-speed medium flow generated at the throttling port from eroding and damaging the sealing surface.
2. The valve handle 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.
