Engineered for your application
A compact cryogenic non-return configuration with two hinged closure plates. The dual-plate architecture is selected for line conditions, mounting orientation and the required reverse-flow response.
Series limits guide enquiry and are not verified availability or approved operating limits for every size, pressure and operator combination. Confirm the selected design and pressure-temperature rating.
Technical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | NPS 2-36 |
| Pressure ratings | ASME Class 150-1500 |
| Temperature range | Down to -196°C; upper limit to confirm |
| Construction | Two hinged closure plates |
| Operation | Automatic non-return |
| Medium | LNG / LPG; exact process medium to specify |
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: two RF flanged line connections
| Connection detail | Connection / selection requirement |
|---|---|
| Connection options | RF / RTJ flanged / butt weld (BW) |
| Mating interface | Confirm end standard, facing or weld preparation, pipe dimensions and installation envelope. |
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 and bonnet | Cryogenic stainless steel; selected grade to confirm |
| Trim, seats and seals | Selected material schedule to confirm |
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.
- Dual-plate closure
- Compact inline installation
- Automatic operation without an external drive
| Engineering data | Configuration requirement |
|---|---|
| Dynamic conditions | Specify flow velocity, pump rundown, reverse flow and installation orientation. |
| Mechanical interface | Confirm connection style, hinge clearance, pressure loss and the approved installation envelope. |
Series limits guide enquiry and are not verified availability or approved operating limits for every size, pressure and operator combination. Confirm the selected design and pressure-temperature rating.
The image illustrates a flanged arrangement. Disc travel, spring selection and transient performance require the selected assembly data.
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.
