Features that Add Value:

  • Bonnet extension/ extension column keep packing rings away from cryogenic temperatures, and within its operating range
  • Thermal stabilization treatment conducted on body and obturator to ensure dimensional stability and to avoid distortion during temperature cycles
  • Cavity relief pressure arrangement to prevent thermal effect
  • Seat and disc hardfaced to prevent seizing and galling

Versatile Solutions:

  • Available in a wide grade of metallurgies for a range of low temperature applications.
  • ValvTrac™ RFID tags for reliable digital traceability
