DESIGN FEATURES :
  • Seat face: Ground and lapped to a smooth finish.
  • Flexible Wedge with low center stem –wedge contact. Wedge is ground and lapped to a smooth finish and closely guided to prevent dragging and seat damage.
  • Non-rotating stem with precision ACME threads and burnished finish. Double ACME threads for faster operation.
  • Body and bonnet joint accurately machined.
  • Each valve is shell, seat and backseat pressure tested.
  • Valves are available with socket weld ends.
  • Yoke bushing can be lubricated to minimize friction and prolong life of the stem.
  • Body and bonnet castings are precision machined.
  • Gland has two-piece construction for easy alignment.
  • Valves are specially cleaned and processed for oxygen or cryogenic service and are then sealed to prevent contamination.
  • Bonnet chamber ventilation, in order to prevent excess pressure build up caused by trapped cryogenic liquids, is available upon request.
  • Each valve has a unique certification number that is traceable to the valve certification sheet which includes MTR data, pressure test report, inspection report and certificate of conformance.
  • Other available options as follows:
    » Alternate valve materials
    » Alternate trim materials
    » Non-extended design
    » Other options available as specified
