Applications
Liquid HydrogenTechnical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | DN 15-250 / NPS 1/2-10 - series scope |
| Pressure ratings | ASME Class 150-300 |
| Construction | Lift-type check; extended service tower; thermal barrier |
| Operation | Automatic / self-acting |
| Medium | LH2 / liquid hydrogen |
| Insulation options | Vacuum jacket with multi-layer insulation or non-jacketed arrangement |
| Seat options | Metal/PCTFE or metal/metal; selected leakage criterion to specify |
| End standard | Butt weld to ASME B16.25 |
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: an inline lift-check body with two butt-weld stubs, an extended service bonnet and bolted top cap; no handwheel or actuator
| Connection detail | Connection / selection requirement |
|---|---|
| Process ends | Butt weld to ASME B16.25; confirm the selected pipe schedule. |
| Insulation interface | Define the jacket, vacuum boundary and extension length separately from the process connection. |
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 | 304L / 316L stainless steel |
| Trim / seats | Selected cryogenic metal and polymer trim; confirm grades for LH2 |
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.
- Automatic lift-check function
- Extended service arrangement
- Thermal-barrier design
| Engineering data | Configuration requirement |
|---|---|
| Process duty | Specify LH2 phase, design temperature, pressure, flow and differential pressure. |
| Selected assembly | Confirm insulation interface, materials, leakage acceptance and project test documentation. |
Series data guide enquiry and are not verified availability or approved operating limits for every size, pressure and execution. Confirm the selected LH2 configuration and pressure-temperature rating.
The published family range includes globe and check constructions. Confirm available lift-check sizes, opening pressure and orientation for the selected model.
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.
