By using an extended bonnet, the packing, gaskets and seals of ColdFlow valves are protected from cryogenic temperatures, thus ensuring their sealing properties. Optional special gaskets and packing can be used to operate at temperatures as low as -69 °C. Depending on the application, Flowserve cryogenic valves are available with a top entry design for the easy maintenance of valves located in a cold box or with a simple extended bonnet attached to the valve body.

Features & Benefits
- High Impact Strength at low-temperature and minimum heat transfer body design
- Cold Box Cryogenic application design with fabricated bonnet extension
- Double Top Stem Guiding moves the critical function of assuring alignment of the trim out of the flow path
- Plug Contours provide flow characteristics with higher rangeability than cage designs
- Floating Seat is clamped in-place after alignment to ensure tight-shutoff and easy service
- Severe Service Trim options can easily be designed or retro-fitted into standard trim valve
