• Sleeved Plug Valves

    Only Tufline®Sleeved Plug Valves offer all these unique features:

    • Improved performance and greater reliability in traditional ball and gate valve applications.
    • A large, circumferential sealing surface.
    • No cavities where flow media can accumulate, contaminate, or mix.
    • High reliability, even after being left open or closed for extended periods of time.
    • Bi-directional flow.
    • Quarter-turn operation.
    • Positive, in-line adjustment of both primary and secondary seals. 360┬░ lips surround the ports, protect the sleeve, and provide self-cleaning action as the plug rotates.
    • Flanged, screwed, socket-weld, and butt-weld ends. Other connections available upon request.
    • Simple actuation, compact size, configurations, on/off, and throttling service all allow more flexible and economical system design.

  • 2-Way Fully Lined Plug Valve

    • These valves are more versatile, and often out-perform, alloy valves.
    • More economical than alloy valves.
    • With FEP and PFA lining, cast, dovetail recesses and machined grooves lock the lining to the valve body casting. The locked-in lining is virtually impervious to shrinking, stress-cracking, collapse, or blowout.
    • Unlike alloy valves, there is no need to inventory different valves for various applications.
    • There is less chance of costly and dangerous installation errors.
    • Media contamination is prevented.
    • Positive shutoff.
    • FEP and PFA locked-in lining.
    • Tufline Lined Ball valves have a metal-to-metal body joint to control compression of the liner for assured sealing.
    • The seats are easily and quickly replaced.


    Both the standard and full-port valves are available with extended packing for enhanced control of fugitive emissions.
