Danfoss HRB 3 PN10 15/4 rotary 3-way Rp½ (065Z0398) is superseded by ESBE AB VRG131 DN15 Kvs 4 Rp ½" (11600600). It is the same physical component under a different brand.
Side by side
Old value first, replacement second. Where a figure is missing, we have not published one rather than estimate it.
How we know
Every claim on this page has a source, and they are not equally strong. A manufacturer confirming something in writing is not the same as several sellers listing it the same way, so the page says which one it is rather than letting both read as certain.
From the manufacturer’s datasheet.

From the manufacturer
These answers are about the Danfoss range, not about this record. We asked, they answered, and the scope of each answer is inside the sentence — read it before applying it to the part in front of you.
On district heating units, control valves and motors (AMV/AME actuators and VM2/VS2 valves) can ALWAYS be replaced individually. There is no technical reason to change a whole unit because a motor or valve has seized or burnt out. A full replacement only becomes relevant once the plate heat exchanger is corroded or scaled, or the pipework itself is rusting.

The application key is not tied to a serial number and can be moved freely to another controller of the same type; the new controller then needs configuring. A2xx keys fit both ECL 210 and 310, while A3xx fit only the 310, which has the extended hardware.

Same kind of part
Someone looking up one discontinued circulator is usually holding a box of them. These are the other parts of the same kind we have documented.

This record says what the catalogue holds about these two parts. It does not confirm that the replacement fits your installation, is in stock, or is safe to install — that is for a professional looking at the actual part. Identification is at component level, not an official manufacturer endorsement.
