Danfoss product code decoder — every industrial code family. Prefix explanation across all Danfoss divisions: refrigeration valves (003Z AB-QM PICV, 032F EVR solenoid, 068Z TEX/TQ expansion, 023U EEV), HVAC (065Z VRB balancing valves, 065B VRG rotary mixing, 013G RA-N radiator, 084H ETS electronic temperature), pressure switches (017B BCP boiler, 060G KP2/KP7 refrigeration, 060H DST industrial), controllers (084H EKC/EKF, 080Z AK2), drives (132B/F VLT FC series, 175/176 automation drives), and industrial (148B PVG proportional, 011L RA-C). Includes typical part-number breakdown, obsoleteness/legacy notes, and cross-links to cBallast product pages.
Every Danfoss part number begins with a three-character series prefix that tells you the product family, the physical connection type and, roughly, the operating pressure class. Once you can read the prefix, the rest of the number is a size / range / voltage suffix that reads off directly from the Danfoss catalogue page. This reference gives every industrial-catalogue prefix Danfoss currently uses across refrigeration, HVAC, drives and industrial automation — useful when you have only a code on a nameplate or PO line and need to identify the equipment family before pricing a spare or replacement.

A typical Danfoss part number reads: 065B2432 (VFGS2 DN25 Kv=6.3). Break it down as:
Not every family follows the same 3+1+1+1+2 pattern — the drives (131B/132F/134B) use a longer 3+1+4 pattern where the trailing digits code kW and voltage. Refer to the specific product catalogue for the exact size-code mapping. When in doubt, look up the code in the Danfoss Store product finder (public URL store.danfoss.com/en/p/<code>) — that page shows the product family, technical drawing and current successor code (if any).
Danfoss maintains active superseded-part lookups but not everywhere. For older codes not on the current price list:
If the code returns nothing on the Danfoss Store search, it is either fully obsolete (no replacement) or an OEM-specific customer number that bypasses the public catalogue. In the second case, contact the Danfoss local sales office with the OEM's serial number for the equipment.
Series prefixes and product families above are the Danfoss current-catalogue coding as published on the Danfoss Store, plus documented legacy prefixes for parts still in service. Individual part-number size codes vary by series and generation; verify with the Danfoss Store lookup or the local Danfoss sales office before ordering.
