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.
