Critical Notes for Lined Valves

Corrosion resistance – The fluoroplastic lining (FEP/PFA/PTFE) provides excellent resistance to almost all chemicals except molten alkali metals and some fluorine compounds at high temperatures. Always verify compatibility with your specific media.
Temperature limitation – The valve’s maximum operating temperature is limited by the lining material. Do not exceed +180℃ for FEP, +200℃ for PTFE/PFA. For higher temperatures, a lined valve is not suitable.
No cooling fins on stem – This valve has a standard stem. For lined valves, high stem temperatures are less critical because the lining isolates the media, but ensure the diaphragm and packing are compatible with the process temperature.
Avoid vacuum service – Fluoroplastic linings can collapse under vacuum (especially at elevated temperatures). For vacuum applications, a special vacuum-resistant lining design is required. Consult the supplier.
Abrasive media – Lined valves are not recommended for abrasive slurries (e.g., with sand, crystals) as they can wear through the soft lining.
Electrostatic discharge – For flammable media, ensure the valve has anti-static design (conductive PTFE lining or grounding device).
Installation – Use gaskets suitable for lined flanges (full-face gaskets recommended). Do not overtighten bolts to avoid damaging the lining.
Positioner is included – Enables precise modulating control. Default flow characteristic is linear. Equal percentage available upon request.
