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.
- Side-entry body joints
- Extended stem keeps the drive above the cold zone
- Hydraulic operating package
| 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.
Specify bore, differential pressure, seat arrangement, trapped-liquid relief and required test documentation.
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.
