Product Overview
PFA identifies this product's confirmed lining, rather than a generic name for every fluoropolymer. Selection still depends on the complete fluid composition and the pressure-temperature conditions of the actual valve assembly. American-standard configuration does not by itself identify a particular API specification, flange class or standard edition.
Selection and Ordering Notes
- State the required American-standard design references, flange class, facing and installation dimensions.
- Provide all process and cleaning chemicals, concentrations and operating conditions for compatibility review.
- Confirm the PFA-lined wetted arrangement, plug and stem sealing details and body material.
- Check gearbox access, operating frequency and the required shutoff acceptance criterion.

Frequently Asked Questions
Is PFA the lining supplied for this plug-valve page?
Yes. PFA is the confirmed lining for this American-standard configuration. Identify the exact model and wetted arrangement in the quotation; do not substitute PTFE or FEP without agreement.
Does American-standard mean this valve automatically meets my project's API specification?
No specific API or ASME document or edition is established by that general description. Send the required design, connection and inspection standards and obtain explicit confirmation for the quoted valve.
Can I use it with a chemical mixture containing several components?
Provide the complete mixture, concentrations, cleaning fluids and pressure-temperature conditions. Request approval of the lining and all exposed seals for the selected assembly rather than assuming PFA makes every service acceptable.
