Rated 5 out of 5Â by Philjon Mid position 3 port valve
Fitted today as a replacement, time will tell if its as good as the other reviewers say, bit on the pricey side.

What I like about the Honeywell is that it is exactly the same as the previous item fitted 43 years ago, so it was an easy replacement to fit. There appeared to be nothing wrong with the original valve, but there seemed to be nothing else that could be causing poor circulation. With the new Honeywell the system now works like a dream.

Good quality. Previous ones have outlasted cheaper versions. Buy cheap buy twice or spend more on a good quality one. Pay for fitting once not twice!

I purchased an item "Flowmaster 27901SX 3-Port Motorised valve" from its description to replace a worn our Honeywell 3-port valve after 32 years good service. Half the price of the Honeywell. Fitting was a direct replacement to the old one and took only and hour to do. Re-commissioned the system and realised it was a mistake. The valve head juddered on opening to 2 ports and created water hammer on closing the C/H port. There is very little built in time delay on opening and closing to any of the 3 positions. Cause "This has a rotary designed valve internals. Replaced immediately with a Honeywell V4073A 3 port valve with built in time delays and the correct internal design valve internals. It cost more than twice the price of the Flowmaster but operates as it should in a Y-3 port system. Do not be caught out with the Flowmaster inferior product due to its price !!
