Has anyone experienced problems with NIBE 3 port valves, which is actually a Honeywell product (though not the V4404c fully diverted 3-port).

It's a motor open spring close design, but we have had 2 fail in the last month on brand new installations, I just wondered if there was a bad batch issue.

NIBE visit and replace so not a time issue for us, but does not help customer confidence.
