Engineered for your application
An extended-bonnet LH2 globe valve combining bellows and gland packing with a thermal-barrier arrangement. Manual operation is illustrated; insulation and maintenance access are defined around the selected installation.
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.
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 | Extended globe; bellows and gland packing; thermal barrier |
| Operation | Manual handwheel |
| 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 globe body with two butt-weld stubs, extended cold bonnet, vacuum interface disc and manual handwheel
| 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.
- Thermal-barrier cold section
- Bellows and gland stem sealing
- Maintenance access outside the cold box
| 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.
DN15-250 and Class150-300 describe the combined LH2 family. Confirm the size/class matrix for this manual globe construction.
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.
