Triac Series F91 unibody flanged ball valves feature a high quality investment cast body and end. They are available in 1/2” through 6” and are regular port. Superior leak protection is accomplished by using our patented “pyramidal” stem seal system shown in the graphic below. This advanced system protects against wear and leakage experienced by ordinary ball valves.
Reinforced TFE seats are standard, but various options are available for seat materials. The 50/50 seat option is excellent for services that call for higher temperatures and more difficult applications including steam. Call or contact us for details.
The Series F91 Fire Safe Unibody Flanged Manual Ball Valves are also available with a Pneumatic Spring Return Actuator, Double Acting Actuator or Electric Actuator.
