Butt weld (BW) connectionLH2 cold-box bellows shut-off valve
Butt weld (BW)
A manual cold-box shut-off valve with a long cryogenic extension and metallic bellows sealing. Weld-in vacuum interfaces and optional thermal intercepts are selected to match the insulated pipework and heat-load budget.
Size and pressure options require technical confirmation.

Engineered for your application
A manual cold-box shut-off valve with a long cryogenic extension and metallic bellows sealing. Weld-in vacuum interfaces and optional thermal intercepts are selected to match the insulated pipework and heat-load budget.
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.

Liquid HydrogenTechnical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | DN 2-250 - rating dependent |
| Pressure ratings | PN6 / PN25 / PN40 - size dependent |
| Construction | Bellows-sealed cold-box globe; angle arrangement illustrated |
| Operation | Manual handwheel |
| Medium | LH2 / liquid hydrogen |
| Size / rating selection | PN6: DN2-250; PN25: DN2-150; PN40: DN2-80 |
| Body options | Angle or straight pattern; angle body illustrated |
| Vacuum boundary | Weld-in flange, jacket or selected interface |
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 angle body with horizontal and downward butt-weld stubs, long cold extension, thermal-intercept disc and manual handwheel
| Connection detail | Connection / selection requirement |
|---|---|
| Process ends | Specify pipe OD, wall thickness, material and weld preparation. |
| 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 | Selected stainless-steel pressure-part schedule |
| 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.
- Metal bellows stem sealing
- Long cold-box extension
- Manual cold-line isolation
| 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.
Published size bands are separate pressure-dependent selections. Confirm allowable differential pressure and operating pressure at the selected temperature.
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.
