Medium conditions for the use of fluorine lined valves

Users are selecting various types Fluorine lined valve At this time, it is necessary to understand and master the technical conditions of use as much as possible in order to select and use the valve well, and improve its service life. When encountering situations beyond the scope of technical conditions, it should be raised to the manufacturer for joint consultation and corresponding measures should be taken to solve the problem. Below, we will introduce the medium conditions and precautions to be taken when using fluorine lined valves.
The medium conditions used for fluorine lined valves should not have hard particles, crystals, impurities, etc., in order to prevent the valve from grinding the fluorine lined plastic layer or PTFE corrugated pipe of the valve core and seat during opening and closing operation. When selecting media with hard particles, crystals, and impurities, the valve core and seat can be made of Hastelloy alloy.
Fluorine lined valves should be selected with the correct valve diameter according to the required flow rate (Cv value). When selecting, the valve diameter and opening degree should be calculated based on the required flow rate (Cv value) and other technical parameters. If the valve diameter is selected too large, it will inevitably cause the valve to operate at a low opening degree for a long time. Coupled with the pressure of the medium, this can easily cause the valve core and stem to be impacted by the medium, resulting in vibration of the valve. The valve core and stem may even break under the impact of the medium for a long time.
