Lined fluorine angle stop valve
I. Introduction:
The J44F46 lined angle-type stop valve is suitable for use in pipelines conveying various concentrations of aqua regia, sulfuric acid, hydrochloric acid, organic acids, strong acids, and strong oxidizing agents within the temperature range of -50℃ to 150℃. The FEP version is also applicable to pipelines conveying various concentrations of strong alkaline organic solvents and other corrosive gaseous and liquid media. A stop valve refers to a valve whose closing member (disc) is driven by a stem and moves up and down along the central axis of the seat. It is mainly used to open or cut off the medium in the pipeline, but cannot be used for throttling. The J44 type angle-type stop valve has the advantages of compact structure, flexible operation, strong corrosion resistance, and short stroke. It is widely used in petroleum, chemical, and other pipeline systems to cut off the medium. However, stop valves with plastic lining must not be used for flow regulation, as the high-speed medium flow at the throttle port may erode and damage the sealing surface.
