PTFE-lined butterfly valves manufacturers in United States

PTFE-lined (Teflon) butterfly valves are made by a mix of specialty lining shops and established valve manufacturers; buyers should look for suppliers who explicitly line the valve body/seat with PTFE/PFA, specify chemical compatibility and have experience with your service (temperature, pressure, media). This list compiles manufacturers and fabricators shown in the provided search evidence that offer PTFE- or PFA-lined butterfly valves.

What to specify in your RFQ

Manufacturers quote faster and more accurately when your request covers these points.

  • Size (nominal diameter)

    Specify the pipe/valve nominal diameter and flange/wafer style so the manufacturer can confirm availability and rating.

  • Liner material and thickness

    State whether you need PTFE or PFA lining, full-lining vs. seat-only, and any minimum lining thickness or special compounded fluoropolymer.

  • Pressure class and rating

    Provide the required maximum working pressure / pressure class (e.g., ANSI class, PN) to ensure the valve body and liner are rated appropriately.

  • Temperature range and media

    List operating temperature extremes and the chemicals or slurries handled so the supplier can confirm chemical compatibility of PTFE/PFA.

  • End connections and standards

    Specify wafer/lug/gear type, flange standards (ANSI, DIN), and any applicable industry standards (e.g., MSS, API).

  • Actuation and accessories

    State whether you need manual lever, gearbox, electric/hydraulic/pneumatic actuator, positioners, or limit switches.

  • Quantity and delivery target

    Give the required quantity and target delivery date; lining work and special fabrication affect lead time and MOQ.

Sourcing FAQ

How do I verify a supplier actually manufactures PTFE-lined butterfly valves?
Ask for the supplier's product pages, photos/spec sheets showing PTFE/PFA lining, manufacturing or lining facility information, and examples of previous orders or data sheets that explicitly state 'PTFE/PFA lined' or 'we manufacture'.
What typically drives lead time for PTFE-lined butterfly valves?
Lead time is affected by lining method (full-lining vs seat insertion), lining curing and inspection, actuator procurement, and whether the valve body is standard or custom; lining shops may add several weeks for fabrication and testing.
Are there minimum order quantities (MOQs)?
MOQs vary by supplier and by whether the valve is a standard model or a custom lined unit; lining shops sometimes accept single-unit fabrications while OEM manufacturers may have higher MOQs—always confirm with the quoted supplier.
Which certifications or tests should I request?
Request material certificates for PTFE/PFA, pressure test records (hydrostatic/seat tests), and any applicable compliance to standards you require (e.g., MSS, API, FDA for food applications) and evidence of leak/chemical compatibility testing.
