Butterfly valves with a female and a male BS4825-4 IDF (International Dairy Federation) coupling connection.

This part is a combination of a hygienic butterfly valve, a liner, a nut and a male part.

This is a commonly used combination in piping systems, especcially where high hygiene standards are required; such as dairy and food production lines.

A complete IDF coupling connection consists of a male part, a liner, a slip nut and a gasket.

The materials, dimensions and maximum roughness of IDF couplings are standardized in the BS4825-4 standard.

STEP (.stp) 3D CAD file format

The CAD files are saved in the STEP (.stp) file format. That is an export/import file format recognized by all solid modeling programs.
After importing a step file into your software program, you can save it in the format of your program.
This allows you to build your own 3D CAD library with parts made by different software programs.

Programs that work excellent together with step files include: Autodesk Inventor, Solidworks, Fusion 360, Catia, Solid Edge.

Main dimensions according to the BS4825 part4 standard

Because the main dimensions are also laid down in the BS4825 standard, it was possible for us to make this 3D CAD collection. We only make 3D CAD models, we are not a fitting manufacturer or supplier. However, you can be sure that these 3D models have the same dimensions as the fittings "in real life".
