PEEK and PTFE Valves

Polymer valves are used in a number of industrial applications. At Poly Fluoro Ltd Ltd., parts are available in a range of dimensions and profiles, all customizable based on client requirements and OEM drawings.

Parts are CNC machined to tolerances of up to +/- 0.02mm – which is in line with best-in-class global tolerance norms.

Our parts go through a rigorous inspection process, including raw material inspection, in-process inspection, and final inspection. All parts are assigned batch numbers with full traceability to the raw material and process parameters.

For high volume parts, special inspection gauges and fixtures are employed to ensure 100% inspection before dispatch.

Material selection is essential in getting the correct solution for a given application. Poly Fluoro Ltd understands the strengths and limitations of each material and accordingly works with the end-users to narrow in on the most effective option.

Material Name Main Properties Notes/Applications Temperature Range

Virgin PEEK

Excellent chemical resistance and mechanical properties at elevated temperatures High tensile strength and dimensional stability

FDA approved Most effective as a seal, backup ring, V-packing or Chevron seal Used as rotary seals in Nuclear applications

-40°C to 260°C

Carbon filled PEEK

Many similar properties to Virgin PEEK. Particularly suitable for elevated temperatures and high load situations.

Low coefficient of friction and suitable for many extremely corrosive applications

-40°C to 260°C

Glass filled PEEK

Many similar properties to Virgin PEEK. Particularly suitable for elevated temperatures and high load situations.

Low coefficient of friction and suitable for high wear applications

-40°C to 300°C

PTFE filled PEEK

Many similar properties to Virgin PEEK. Particularly suitable for elevated temperatures and high load situations.

Higher lubricity than Virgin PEEK. Suited to sealing applications where start-stop or rotary motions are involved at higher RPMs

-40°C to 260°C
