The control valve is designed specifically for use in ‘cold box’ applications. It is a single-seated, body-guided globe style with threaded seat ring.
The extended neck allows the body to bonnet
flange to be outside the cold box, simplifying maintenance and providing a low
‘cool down weight.’ This design is generally used in throttling and/or
isolation control of cryogenic liquids and gases to -450°F (-268°C).
•
It offers
low cool down weight because there are no flanged joints in the cold box area
and the small body mass keeps heat absorption at a minimum.
•
Low
conduction through the neck extension and the valve stem makes the valve
ideally suited for super-cooled environments.
•
Extended
body neck design allows removal of the seat ring and plug without disturbing
the cold box purge, vacuum or insulation.
•
No
gasketed joints are inside the cold box or line insulation, eliminating
potential leak paths. Standard seat ring wrenches are available for removing
trim.
•
Standard
plug design provides metal seat and Class IV shut-off.
•
Optional
lapping and proper actuator selection allow for Class V shut-off capability.
•
A soft
seat plug design is available for Class VI leakage.
•
Preferred
mounting is 20 to 90 degrees from horizontal.
•
The
optional Ice-Breaker packing box is available to prevent ice formation on the
valve stem and coupling.
•
Mounting
plate for cold box installation is offered as an accessory.
