Engineered for your application
A dedicated liquid-hydrogen non-return assembly with an insulated body and a guided, spring-return lift closure. The passive valve is selected with the flow regime and installation orientation.
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.
Technical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | NPS 1/2-6 / DN 15-150 |
| Pressure ratings | ASME Class 150-600 |
| Temperature range | -253 to +120°C |
| Construction | Vacuum-jacketed guided lift disc; spring return |
| Operation | Automatic non-return |
| 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: two RF flanged line connections
| Connection detail | Connection / selection requirement |
|---|---|
| Connection options | Socket weld (SW) / butt weld (BW) / RF flanged |
| 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.
- Dedicated LH2 non-return duty
- Guided lift closure
- Vacuum-jacketed body
| Engineering data | Configuration requirement |
|---|---|
| Non-return duty | Specify normal/minimum flow, allowable reverse flow, cracking pressure and mounting orientation. |
| Insulated-line interface | Confirm process pipe, jacket boundary, vacuum performance and service clearance. |
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.
No cracking-pressure value, pressure-loss coefficient or transient closure guarantee is inferred from the illustration.
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.
