| Medium | LNG / NG, LOX / O2, LN2 / N2, LAr / Ar |
| End connections | Weld ends - preparation to specify |
| Operation | Pneumatic cylinder with manual override in illustrated arrangement |
| Flow direction | Under the disc to above the disc |
| Inspection reference | GB/T 24918 |
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: a compact block body below a bolted bonnet and long neck, with an open-yoke pneumatic cylinder and T-bar manual override
| Connection detail | Connection / selection requirement |
|---|---|
| Connection options | Weld ends - preparation to specify |
| Interface selection | Specify the end standard, nominal size, pipe dimensions and required mating interface. |
| Weld preparation | The series is documented as welded. Specify BW/SW type, bore, pipe OD and wall thickness; no weld preparation is inferred from the illustration. |
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, bonnet and stem | Stainless steel; exact grade to specify |
| Seal | Hard alloy; grade to specify |
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.
- PN160 nominal-pressure series
- Hard-alloy sealing
- Extended-neck pneumatic assembly with manual override
| Engineering data | Configuration requirement |
|---|---|
| Duty definition | Specify differential pressure, flow direction, leakage requirement and operating frequency. |
| Pneumatic controls | Specify air supply, fail action, control signal, feedback and required manual-override operation. |
Sizes and pressure ratings depend on construction, materials and configuration. Confirm the selected pressure-temperature rating with the quotation.
Fail-open/fail-close action, spring arrangement, control supply, closing time and any ESD or SIL documentation are specified for the selected assembly; the photograph does not establish these functions.
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.
