Are there any views on which 2-port valve is more reliable long term about the Danfoss HP22 2 and the Honeywell V4043H?
They will be in a CH circuit.

I'm with Pete on this.

I know of several 2 port Honeywell's that have been working for over 20 years and one in my mums bungalow was installed when it was built in 1981 and is still working perfectly.

Old honeywells yes without a doubt new ones are no where as good as what they where.
Danfoss are not that bad as such but can be a bit clunky on closing
Honeywell every time for reliability and lifespan.

Or, Sunvic are ok if you like changing valves regularly.... ;)
