PFA-Lined Valves
Butterfly, ball, diaphragm, ball-check, visual-check, plug and wafer-check families with a lined wetted path. Final suitability depends on the exact fluoropolymer, permeation risk, pressure-temperature combination and media chemistry.
Why a lined flow path
Separate structural body material from media-contact material
A fluoropolymer-lined valve uses a structural body with a separate lining at the wetted surface. This can broaden the materials considered for a chemical service, but it does not remove the need to review media compatibility, diffusion, pressure, temperature and cycling.
- PPFA-lined wetted surfaces
PFA lining options are available across butterfly, ball, diaphragm, check and plug valve families.
- MMultiple valve mechanisms
Select the valve type by control function, pressure loss, solids behavior, required shutoff and maintenance access.
- CCompatibility before application labels
State the complete chemical name, concentration, contaminants and normal, cleaning and upset temperatures.

Selection matrix
PFA-lined valve product range
Compare valve mechanism, size, pressure, construction and operation before preparing the RFQ.
| Valve family | Published size range | Pressure reference | Construction reference | Operation |
|---|---|---|---|---|
| PFA-lined butterfly valve | DN50–DN900 (2–36 in) | 1.0 MPa | Two-piece body, PFA-coated disc and PFA / PTFE seat references | Handle, gear, pneumatic or electric |
| PFA-lined ball valve | DN15–DN300 (1/2–12 in) | 1.6 MPa | Carbon- or stainless-steel body references with PFA / FEP lining and PTFE seats | Handle, gear, pneumatic or electric |
| PFA-lined diaphragm valve | DN15–DN300 | 1.6 MPa | FEP / PFA / PTFE diaphragm references with elastomer backing options | Manual or pneumatic |
| PFA-lined ball check valve | DN15–DN200 | 1.6 MPa | Fluoropolymer-lined body with PTFE ball reference | Self-acting check duty |
| Visual ball check valve | DN15–DN200 | Confirm by selected construction | PFA-lined body with borosilicate-glass viewing section in the catalog | Self-acting check duty |
| PFA-lined plug valve | DN15–DN300 | 1.6 MPa | PFA / FEP / ETFE lining references | Manual or actuated |
| Wafer lined check valve | DN50–DN600 | 1.6 MPa | Wafer body with fluoropolymer-lined wetted surfaces | Self-acting check duty |
Match temperature to the complete construction
Temperature capability depends on the valve type, lining, seat or diaphragm, pressure and medium. State normal, cleaning and upset temperatures.
PFA, FEP, PTFE and ETFE are not interchangeable labels
The order should identify the exact lining and every wetted material. Generic fluoropolymer property tables do not establish the rating of an assembled valve.
State the required design and connection standards
Include the required API, ASME, EN, ISO, JIS or MSS references in the project specification.
Confirm project-specific approvals
If a chemical, electronics, food or pharmaceutical project requires named approvals or inspection documents, include them in the RFQ.
Selection support
Qualify the lining before qualifying the valve.
A complete chemical and operating profile is required before a PFA-lined valve configuration can be recommended.
