Engineered for your application
A cryogenic screw-down non-return selection for LNG marine pipework, combining automatic non-return duty with a manually imposed shut-off position. Confirm the selected disc and stem arrangement for the system.
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.
Technical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | Nominal size to specify |
| Pressure ratings | Pressure rating to specify |
| Temperature range | Cryogenic design temperature to specify |
| Construction | Screw-down non-return (SDNR) |
| Operation | Automatic check action with manual screw-down isolation |
| Medium | LNG service; exact process medium to specify |
Nominal pressure and ASME class are different rating systems. Confirm the pressure–temperature rating for the selected material and design.
End connections
Define the interface.
Shown configuration: a flanged globe-pattern body and extended manual handwheel assembly
| Connection detail | Connection / selection requirement |
|---|---|
| Connection options | End connections to specify |
| Mating interface | Confirm end standard, facing or weld preparation, pipe dimensions and installation envelope. |
| Configuration selection | Port pattern and end standard are project selections; the delivery reference does not establish a common dimensional schedule. |
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.
- Combined non-return and manual shut-off duty
- Extended manual upper assembly illustrated
- Marine line integration selected for the project
| Engineering data | Configuration requirement |
|---|---|
| Operating duty | Specify required flow direction, check response, manual shut-off duty and line conditions. |
| Marine documentation | Confirm class-society requirements, selected design standard, material traceability and tests. |
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.
No class approval, nominal range, cracking pressure or closing time is inferred from delivery history or the illustration.
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.
