Engineered for your application
A rising-stem cryogenic gate package for full-open or shut-off duty in larger process lines. The extended bonnet separates the packing and hydraulic drive from the cold pressure body.
Series limits guide enquiry and are not verified availability or approved operating limits for every size, pressure and operator combination. Confirm the selected design and pressure-temperature rating.

End connections
Define the interface.
Shown configuration: two RF flanged line connections
| Connection detail | Connection / selection requirement |
|---|---|
| Connection options | RF / RTJ flanged / butt weld (BW) |
| Mating interface | Confirm end standard, facing or weld preparation, pipe dimensions and installation envelope. |
The illustration shows one configuration. Published connection alternatives are options for enquiry; their availability depends on size, rating, material and design. Installation dimensions come from the drawing, not the illustration.
Materials
From body to seal.
| Component | Material / option |
|---|---|
| Body and bonnet | Cryogenic stainless steel; selected grade to confirm |
| Trim, seats and seals | Selected material schedule to confirm |
Published material alternatives are configuration-dependent. H.F. denotes hard facing; the exact grade and material certificates are confirmed with the offer.
Selection notes
Defined around your application.
- Rising-stem isolation
- Extended bonnet
- Hydraulic linear cylinder
| Engineering data | Configuration requirement |
|---|---|
| Hydraulic system | Specify working pressure, fluid, supply/return interfaces and the location of the power unit. |
| Motion and emergency duty | Confirm load, speed control, accumulator requirements, manual override and the required loss-of-pressure action. |
Series limits guide enquiry and are not verified availability or approved operating limits for every size, pressure and operator combination. Confirm the selected design and pressure-temperature rating.
The illustration does not include a hydraulic power unit. Accumulators, emergency energy storage and fail action are project selections.
Gate valves are selected for isolation; throttling and prolonged partial opening require a separate duty assessment.
Published ratings do not establish suitability for every listed medium. Oxygen cleaning, material compatibility, trapped-liquid relief and project approvals are specified for the selected assembly. Liquid-hydrogen and helium service require a separate temperature and material review.
