Engineered for your application
A liquid-hydrogen ball-valve enquiry reference for specialized isolation duty. The illustrated extended-stem quarter-turn arrangement is developed around a selected hydrogen-compatible material, seat and pressure-relief design.
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.
Applications
Liquid HydrogenTechnical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | Nominal size to specify |
| Pressure ratings | Pressure rating to specify |
| Temperature range | LH2 service down to -253°C; selected limits to confirm |
| Construction | LH2 ball-valve family; arrangement to select |
| Operation | Operator to select; manual gearbox illustrated |
| Medium | LH2 / liquid hydrogen |
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 ball body, long cryogenic extension and manual gearbox
| 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 | The LH2 family statement does not define a common end standard; specify the required interface. |
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 |
|---|---|
| Pressure parts and stem | Hydrogen-compatible grades to select |
| Seats, seals and packing | Qualified LH2 material system to select |
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.
- Dedicated LH2 ball-valve selection
- Extended upper assembly illustrated
- Seat and cavity-relief design specified for the duty
| Engineering data | Configuration requirement |
|---|---|
| Hydrogen design | Provide pressure, temperature, fluid state, leakage requirement, cleanliness and qualification documents. |
| Mechanical definition | Confirm bore, body construction, seat arrangement, operator and end connections. |
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.
Capability for the LH2 ball family is documented, but no universal DN, Class/PN or material schedule is established. PN40 from a globe or safety valve must not be transferred to this product.
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.
