• 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.

• Lower torque ratings.
• Continuous disc/shaft lining.
• Triple O-ring stem sealing components are all isolated from corrosive flow media.
• Spring washer live loaded stem packing. Slim profile disc.
• Completely enclosed shaft bot tom. No springs, seals, or washers to corrode or fail.
• Face-to-face dimensions meet API 609 specifications.
  PFA lining:
• More flexible and less bulky for more reliable and tighter sealing. Excellent permeation resistance.
• High Cv values.

Tufline Fully Lined Accessories are a reliable and economical alterna tive to costly high-alloy products.
