Engineered for your application

A CF8 flanged triple-eccentric butterfly range covering DN50–900. Published PN and ASME ranges describe separate rating options; the cryogenic temperature limit requires confirmation.

Sizes and pressure ratings depend on construction, materials and configuration. Confirm the selected pressure-temperature rating with the quotation.

Applications

LNG Industrial Gases

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.

ARD-BF-003 engineering requirements
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.

the technical record categorises this range for cryogenic service but does not publish a numeric temperature limit for this construction. Confirm the minimum design temperature and trim before selection.

*PN and ASME Class ranges are separate ranges. They are not conversions or a complete size-by-rating availability matrix.

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.
