Working principle and use of the product:
Fluorine-lined globe valve is divided into: Straight through fluorine lined stop valve, straight flow fluorine lined stop valve, Angle fluorine lined stop valve, with compact structure, flexible opening and closing, corrosion resistance, short stroke (generally nominal diameter 1/4) and other advantages, is widely used in petroleum, chemical and other piping system to do truncation medium, but it needs to be emphasized that fluorine lined stop valve is strictly prohibited to do flow regulation, In order to avoid the throttle orifice produced by high speed dielectric flow erosion damage sealing surface.
Fluorine lined stop valve is suitable for all kinds of concentrations of aqua royalty, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants, FEP is also suitable for all kinds of concentrations of strong alkali organic solvents and other corrosive gases, liquid media pipeline use.
Product structure features:
1, plastic lining J41 straight through type, J45 straight slip type, J44 Angle type globe valve, has the advantages of compact structure, flexible opening and closing, strong corrosion resistance, short travel (generally called 1/4) and so on. It is widely used in petroleum, chemical and other pipeline systems as truncation medium, but the plastic lined globe valve is strictly prohibited to be used as flow regulation, so as to avoid the high-speed medium flow erosion at the throttle orifice damage sealing surface.
2, disc and stem design as a whole structure, to prevent the possibility of internal parts out of the valve body due to pipeline pressure fluctuations, compact structure, safe use.
Angle globe valve is a common truncation valve, mainly used to connect or truncate the medium in the pipeline, generally not used to regulate the flow.
Main structural characteristics of Angle globe valve:
