Engineered for your application
A large-bore non-return range with soft- or metal-seat options and published sizes through 36 inches.
Sizes and pressure ratings depend on construction, materials and configuration. Confirm the selected pressure-temperature rating with the quotation.
Technical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | 2–36 in |
| Pressure ratings | ASME Class 150–600 |
| End connections | Butt weld (BW) · Flanged |
| Temperature range | Down to −196°C |
| Referenced design standards | BS 6364; ASME B16.34; B16.25 / B16.5 |
| Referenced pressure / seat tests | API 598; BS 6364 |
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 ends on the pictured configuration.
| Connection detail | Connection / selection requirement |
|---|---|
| Published connection | Flanged, butt weld or RTJ |
| Referenced connection standards | BW: ASME B16.25; flanged: ASME B16.5 (reference reference). |
| Flange facing | RTJ = ring-type joint facing, not a separate pipe-connection family. Confirm RF / RTJ and gasket designation. |
| Weld selection | Specify pipe OD, wall thickness/schedule, material and weld preparation. SW and BW are different connections. |
| 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 | Cast Steel – ASTM A351-CF8(M)/CF3(M) |
| Bonnet | Cast Steel – ASTM A351-CF8(M)/CF3(M) |
| Seat | SOFT: PCTFE METAL: ASTM A276-304(L) / 316(L)-(H.F) |
| Disk | ASTM A351-CF8(M) / CF3(M), A276-304(L) / 316(L)-(H.F) |
| Gasket | SPIRAL WOUND GRAPHITE |
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.
- Full- or reduced-bore configuration
- Bolted, welded or pressure-seal bonnet variants
- Installation orientation to be confirmed for the selected design
Sizes and pressure ratings depend on construction, materials and configuration. Confirm the selected pressure-temperature rating with the quotation.
Published series limits are not a size-by-pressure availability matrix. Materials, temperature capability, leakage class, testing and certification are confirmed for the selected configuration.
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.
