Engineered for your application
A flanged CF8 cryogenic ball-valve range covering DN25–150. The long-stem layout is offered with lever, electric or pneumatic operation.
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 | DN 25–150 |
| Pressure ratings | PN40 |
| Connection | Flanged |
| Design | Long stem |
| Operation | double-acting pneumatic, electric actuator, hand lever, spring-return pneumatic |
| series temperature* | -196°C to +80°C |
| Medium | LNG, LOX, LN2, LAr, CO2 |
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 ball-valve body with bolt-hole flanges, long extension and red lever.
| Connection detail | Connection / selection requirement |
|---|---|
| Published connection | Flanged |
| Flange interface | Confirm standard, pressure class, facing, drilling and mating dimensions. The image alone does not establish any of these. |
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 | CF8 |
| Ball | CF8 |
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.
- Catalogue body: CF8
- Published connections: Flanged
| Engineering data | Configuration requirement |
|---|---|
| Dimension data | Order-specific dimensions required; no matched dimension table is published for this configuration. |
| Installation drawing | Confirm end-to-end length, overall height, flange standard, facing, drilling and operating/removal clearance. |
| Pressure-temperature rating | Obtain the allowable-pressure table or curve versus temperature for the selected body, seat and seals, including minimum and maximum design temperature. Nominal rating and a family temperature range do not define this curve. |
Sizes and pressure ratings depend on construction, materials and configuration. Confirm the selected pressure-temperature rating with the quotation.
*−196 to +80°C is the series/reference range. It does not establish the allowable pressure at each temperature or suitability of every seat, seal and actuator. Confirm the selected assembly’s minimum design temperature and pressure–temperature curve.
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.
