Crane FKX9000 Triple Offset Butterfly Valves


Crane FKX 9000 Triple Offset Valves (TOV) are uniquely suited for industrial environments where high or low temperatures prevent the use of rubber lining elements: e.g., systems using large bore butterfly valves to manage hot steam or isolate areas of a facility. The TOV’s quarter-turn opening and closing provide rapid closing times often needed for safety applications and to  facilitate automation. The TOV also requires less structural support to ensure bubble-tight shut-off making it an affordable alternative to ball valves.

The TOV features an innovative seat angle and Stellite hard-faced body to deliver prolonged seal life and increased abrasion resistance over traditional butterfly valves. Precision machined metal sealing enables reliable bi-directional shutoff for severe services. Reduced disc binding and operating torque combine to cut the total cost of ownership in half.  


  • Optimized seat angle and Stellite hard-facing extend seal life and increase abrasion resistance.
  • Metal-to-metal sealing enables bi-directional shutoff under extreme conditions.
  • Allows superior fugitive emissions control per ISO 15848 and Class BH. 
  • Torque-seated design self-adjusts to distribute seal compression.  
  • Floating seal ring combined with a wide seal supporting gasket eliminates binding and improves performance.


  • Saturated & superheated steam. 
  • Hydrocarbons. 
  • Gasses include hydrogen, oxygen, sulfur (tail gas), and flare gas.
  • Hot gases
  • Chlorinated solvents.
  • Chemical solvents.


  • Sizes from 3” to 64”.
  • DN 80 up to DN 1600 in single cast body design.  
  • ASME Class 150, 300, and 600.
  • PN 10, 16, 25, 40, 63, 100.
  • Temperatures from -76°F to 1022°F (-60°C to 550°C) based on material.
  •  Body configurations include Lug, Double Flanged Short Pattern, Double Flanged Long Pattern.  
  • Special options available.
