Engineered for your application
A top-entry body arrangement giving access to internal components, with an extended bonnet and cavity pressure-relief design.
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 | ½–20 in cast / ½–36 in forged |
| Pressure ratings | ASME Class 150–1500 |
| End connections | Socket weld (SW) · Butt weld (BW) · Flanged |
| Temperature range | Down to −196°C |
| Referenced design standards | BS 5351; 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 top-entry configuration.
| Connection detail | Connection / selection requirement |
|---|---|
| Published connection | Socket weld, butt weld or flanged |
| Referenced connection standards | BW: ASME B16.25; flanged: ASME B16.5. A SW standard is not specified on this page. |
| 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) Cast Steel – ASTM A351-CF8(M)/CF3(M) |
| Bonnet | Forged Steel – ASTM A182-F304(L)/F316(L) Cast Steel – ASTM A351-CF8(M)/CF3(M) |
| Seat | PCTFE/METAL |
| Ball | A182 F304(L)/316(L)+Ni60 |
| Stem | XM-19 |
| Gasket | SPIRAL WOUND GRAPHITE |
| Gland Packing | SS316+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.
- Top-entry access
- Extended bonnet with drip plate
- Floating or trunnion-mounted ball

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.
