Jacketed, steam traced and jacketed-high-performance butterfly valves for rail tank car service.

• These rapid-draining, bottom- mounted, bottom-operated valves provide safe, reliable, and economical service in rail tank cars.
• The low-profile design significantly reduces skidding costs.
• AAR approved (Approval Number E049006).

Tufline steam traced and jacketed butterfly valves provide patented, triple-point prevention of media solidification.

• Both the shaft and the bearings are fully heated.
• The steam is channeled from the shaft, around the full perimeter of the disc, and out the bottom shaft.
• A separate steam path circulates through each side of the body as suring complete and maximum temperature control.

• 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.
