ARD-BV-008 end connection details
Connection detail	Connection / selection requirement
Published connection	Socket Weld
Socket interface	Confirm pipe outside diameter, socket bore, depth and wall thickness for the chosen size. SW is not a threaded or butt-weld interface.
Reference drawing scope	All linear dimensions are in mm. L1 = selected end-to-end length; C = handle length. D = ball bore; CD/G = butt-weld end diameters; ID = socket bore. H1, H2, H3 and h follow the exact drawing datums. DN is the nominal-size mapping of the technical record inch size. Supplied ARD-BV-008 3-piece reference, CF8M body and PCTFE seat, socket-weld ends. This is a reference variant of the current CF8 PN40 catalogue product. Confirm the quoted body, extension and connections before installation.

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-BV-008 engineering requirements
Engineering data	Configuration requirement
Dimension data	Reference table and drawing: DN10, DN15, DN20, DN25, DN32, DN40, DN50. ARD-BV-008 socket-weld reference dimensions.
Installation drawing	Confirm end-to-end length, socket bore/depth, pipe size and wall thickness, overall height 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.

Catalogue construction and supplied reference-arrangement materials are shown separately below the material schedule. Use the approved drawing for the quoted body, trim and connections.

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.
