Engineered for your application
A small-bore forged non-return range with socket-weld or flanged connections.
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 | ½–2 in |
| Pressure ratings | ASME Class 150–1500 |
| End connections | Socket weld (SW) · Flanged |
| Temperature range | Down to −196°C |
| Referenced design standards | BS 6364 |
| Referenced pressure / seat tests | 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: Socket-weld body and bolted cap in an original illustrative assembly; exact supplied construction requires confirmation.
| Connection detail | Connection / selection requirement |
|---|---|
| Published connection | Socket weld or flanged |
| Connection standard | Not specified on this product page. Confirm the mating standard with the offer. |
| 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 | Forged Steel– ASTM A182-F304(L)/F316(L) |
| Bonnet | Forged Steel– ASTM A182-F304(L)/F316(L) |
| Seat | ASTM A276-304(L) / 316(L)-(H.F) |
| Disk | ASTM A182-F304(L)/F316(L) |
| Stem | ASTM A276-304(L) / 316(L) |
| 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
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.
