summary:

J41Fs fluorine lined globe valve refers to a valve whose closing element (valve disc) is driven by the valve stem and moves up and down along the central axis of the valve seat. It is mainly used to connect or cut off the medium in the pipeline, but cannot be used for throttling.

Basic structure of globe valve:
1. The J41F46 straight through type with fluoroplastic lining has the advantages of compact structure, flexible opening and closing, strong corrosion resistance, and short stroke (generally 1/4 of the nominal diameter). It is widely used as a cut-off medium in pipeline systems such as petroleum and chemical industries. However, it should be emphasized that fluoroplastic lined cut-off valves are strictly prohibited from being used for flow regulation to prevent high-speed medium flow erosion and damage to the sealing surface at the throttling port.

2. The valve disc and valve stem are designed as an integrated structure to prevent the possibility of internal components rushing out of the valve body due to pressure fluctuations in the pipeline. The structure is compact and safe to use.

Design features:
1. Fluoroplastic lined J41F46 straight through, J45F46 straight through, and J44F46 angle globe valves have the advantages of compact structure, flexible opening and closing, strong corrosion resistance, and short stroke (generally 1/4 of the nominal diameter). They are widely used as cut-off media in pipeline systems such as petroleum and chemical industries. However, it should be emphasized that fluoroplastic lined globe valves should not be used for flow regulation to avoid high-speed medium flow erosion and damage to the sealing surface at the throttling port.
2. The valve disc and valve stem are designed as an integrated structure to prevent the possibility of internal components rushing out of the valve body due to pressure fluctuations in the pipeline. The structure is compact and safe to use.
3. Fluoroplastic lined globe valves can be selected with inner lining materials according to the conveyed medium and customer requirements, mainly including:
Polytetrafluoroethylene (PTFE, abbreviated as F4)
Perfluoroethylene propylene (FEP, abbreviated as F46)
Fusible polytetrafluoroethylene (PFA)

Ultra high molecular weight polyethylene (PE)
