Applications & selection

Typical uses

  • Isolation duty
  • Corrosive media handling

Industries: Chemical, Pharmaceutical.

Selecting the right construction

Specify nominal bore, flange standard, actuation and pressure-temperature duty. Confirm lining material and required inspection records; body class is not the assembly's operating pressure.

Chemical resistance depends on the polymer, fillers, inserts and process conditions. Confirm the exact medium and concentration; general PTFE properties do not establish a complete assembly's service rating.

Buyer questions

Where are fep-lined ball valves used?

Isolation duty, Corrosive media handling. Typical sectors include Chemical, Pharmaceutical; suitability depends on the actual service conditions.

What sizes can I request for fep-lined ball valves?

2 in nominal bore onwards; ANSI Class 150 body; 3–5 mm virgin FEP lining; spark tested at 20 kV. Final dimensions and tolerances are agreed during quotation.

What should I specify when ordering fep-lined ball valves?

Specify nominal bore, flange standard, actuation and pressure-temperature duty. Confirm lining material and required inspection records; body class is not the assembly's operating pressure.

How is material suitability confirmed for fep lined items?

Submit the exact medium, concentration, temperature, pressure and mechanical duty. Grade availability and compatibility are confirmed for the specific construction; an ASTM reference is not a product certification.
