Engineered for your application
An industrial piston-check selection for cryogenic non-return duty, with separate soft-seat and metal-seat size limits. The piston-type closure is enclosed beneath a service cap and operates without an external drive.
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 | Up to NPS 16; seat/class dependent |
| Pressure ratings | ASME Class 150-2500; seat dependent |
| Temperature range | Cryogenic design temperature to specify |
| Construction | Piston-type non-return; soft or metal seat |
| Operation | Automatic non-return |
| Metal-seat maxima | Class150: NPS16; Class300: NPS12; Class600-2500: NPS10 |
| Soft-seat maxima | Class150: NPS12; Class300: NPS10; Class600: NPS4 |
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.

| Connection detail | Connection / selection requirement |
|---|---|
| Connection options | End connections to specify |
| Mating interface | Confirm end standard, facing or weld preparation, pipe dimensions and installation envelope. |
| Configuration selection | Flanged ends illustrate one requested arrangement; the selected connection is not established by the range table. |
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 cap | Material grade to specify |
| Piston and seat | Soft-seat or metal-seat design to select |
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.
- Piston closure
- Seat-specific pressure and size selection
- Bolted-cap arrangement illustrated
| Engineering data | Configuration requirement |
|---|---|
| Check-valve sizing | Specify normal/minimum flow, fluid state, differential pressure and permitted mounting orientation. |
| Design confirmation | Confirm minimum size, material, connection and cryogenic temperature for the selected assembly. |
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.
Published numbers are upper family limits by seat and Class; a minimum size and a complete size-by-pressure matrix are not established.
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.
