LNGTechnical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | DN 20-300 / NPS 3/4-12 |
| Pressure ratings | ASME Class 150-2500 |
| Temperature range | Cryogenic design temperature to specify |
| Construction | S-pattern globe body; guided plug; extended packing box |
| Operation | Electric linear actuator |
| Medium | LNG / LPG; 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: 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.
- Guided linear control plug
- Extended packing-box assembly
- Electric modulating package
| Engineering data | Configuration requirement |
|---|---|
| Process sizing | Provide minimum/normal/maximum flow, inlet and outlet pressure, temperature and fluid state. |
| Control interface | Specify control signal, position feedback, fail action, shut-off class and available utility. |
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 selected trim requires a confirmed design-temperature range; ordinary cryogenic duty does not establish liquid-hydrogen suitability.
Cv/Kv, characteristic, rangeability, cavitation/flashing behaviour and actuator thrust are calculated for the selected duty.
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.
