Rated 5 out of 5Â by Brianoflancs Just what it says on the tin
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 !!

Had to replace the one in our heating system after 24 years of solid service. Great to find that the valve is still the same size and has the same fittings, even the colour of the wires is the same. Lets hope this one lasts as long.

Rated 5 out of 5Â by BJ183 Siemens Replacement
You've probably read all the glowing reviews for this product; I'm hoping they're all correct. I've just fitted one as a replacement for a Siemens Landis MAV322C 3 Port valve. To be fair the old Siemens valve has been in a long time, 15 years plus, although I have changed the motor head twice in that period. The failure was a bit more terminal this time. I just wanted to say the Honeywell valve was a straight swap for the old one, wiring coding, dimensions, pipe fittings the lot. Just in case you might find that info useful
