Fluorine-Lined Stop Valves Are Mainly Used To Connect Or Cut Off The Medium In The Pipeline

Fluorine-lined stop valve refers to a valve whose closing part (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 it cannot be used for throttling.

Basic structure of stop valve
1. Fluoroplastic fully lined J41F46 straight-through type, J45F46 DC type, J44F46 horn-type cut-off
The valve has the characteristics of compact structure, flexible opening and closing, strong corrosion resistance, short stroke (generally 1/4 of the nominal diameter), etc.
This advantage is widely used in pipeline systems such as petroleum and chemical industries to cut off media, but it needs to be emphasized that
Gas, the cut-off width of the plastic lining is strictly prohibited to be used for flow adjustment to avoid corrosion in the high-speed medium flow generated at the throttle.
Bad sealing surface.
2. The valve disc and valve stem are designed as an integrated structure to prevent internal parts from flushing out of the valve due to pipeline pressure fluctuations.
