Wedge Ball Valve


     

  KEY FEATURES:  
 
  • One piece (forged or cast) body with bolted body cover
  • Fully maintainable in line
  • Bi directional tight shut off
  • Self relieving seat capability
  • Springless seat design
  • Small amount of components
  • Reduced FTF on low pressure classes
 

  BENEFITS:  
 
  • Seats are self-adjusting, assuring leak-tight closure under all operating conditions and valve orientations.
  • Automatic compensation for changes that occur as a result of varying pressure, temperature and wear.
  • Sealing elements are kept in tight contact with the ball to assure an even load on the seats at all pressures, temperatures and at all stages.
  • Ball is wiped clean each time the valve is operated
  • Ball-seat contacts is constantly manteined, extending seat life
  • Minimal number of components
  • Top Entry configuration allows fast, easy, in-line service and permits emergency situations to be safety and quickly esolved
  • All working parts are accessible for service
  • No special tools or training required for maintenance and repair
 

  TYPICAL APPLICATION:  
 
  • Low Temperature and cryogenic
  • Slurry Service
  • Pulp & Paper
  • Oil Sand
  • Mining
  • Fracking
