These size and pressure ranges are subject to technical confirmation. They are not verified availability or approved operating limits. Exact size, rating, materials and design temperature require written confirmation.
Technical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | DN 25-50 |
| Pressure ratings | PN16 / PN25 / PN40 |
| End connections | Flanged · Quick coupling |
| Medium | LO2, LN2, LAr, LCO2, LNG |
| Temperature range | -196 to +60°C |
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: Flanged breakaway body with a quick-connector seat.
| Connection detail | Connection / selection requirement |
|---|---|
| Published connection | Flange（with quick connector seat） |
| Connection standard | Not specified on this product page. Confirm the mating standard with the offer. |
| Flange selection | Specify nominal size, flange rating, facing, drilling and gasket. Do not infer these from the image alone. |
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 | 06Cr19Ni10 |
| Seat | 06Cr19Ni10 |
| Top / closure element | 06Cr19Ni10+RPTFE |

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.
- Flange（with quick connector seat）
These size and pressure ranges are subject to technical confirmation. They are not verified availability or approved operating limits. Exact size, rating, materials and design temperature require written confirmation.
“Top / closure element” follows the component designation in the reference material list.
Available dimensional data: DN 40; 4.0 MPa. Other sizes and ratings require technical confirmation.
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.
