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
