Honeywell V4073A 3 Port Motorised Valve is rated 4.7 out of 5 by 38.
Rated 5 out of 5 by from Quality as expected I'm an industrial automation engineer by trade and have always found Honeywell to be of good quality and reliability. This valve is no exception. It does what it says on the box. The wiring colours and fittings haven't changed in years, so it's a quick, no nonsense replacement for the same model that has just failed after many years of service.

Rated 5 out of 5 by from Direct Replacement My old valve was sticking leading to hot water/rads on at the same time, looks as if someone had also changed the synchro at some point in the past so just decided to change the whole head, wires are same colour as a 20yr old unit so easy to change worked first time and has been fitted about a year now with no problems. Honeywell are not the cheapest but if it lasts another 20yrs I will be happy!!

Rated 5 out of 5 by from Fit and Forget This was a swap for a very unreliable Myson. The one that sticks and requires a persuader to help it along. The Honeywell unit was easy to fit the instructions were good and the job a breeze. If you have to replace a 3 port use Honeywell the reviews alone will tell you it's the only real sensible choice to make if you want trouble free central heating and hot water control. A week prior to swapping this unit I used Sentinel X300 product to flush out the system and after flushing fitted the valve and introduced the Sentinel X100 inhibitor. The whole system is running like new and more efficiently than ever.

Rated 5 out of 5 by from great new for old my old 3 way value motor was broken so this was a direct replacement and very easy to swap. Product feels solid and well built and easy to fit, only time will tell how long it lasts but the previous had lasted at least 20 years.

Rated 5 out of 5 by from Good value Purchased this valve to replace the one on my heating system that was stuck in the open position. The job was far lest tricky than I feared and the cost of the part was great compared to getting a plumb in.

Rated 5 out of 5 by from High quality valve The original V4073A in my system performed faultlessly for 25 years until 2010. In November 2010, I purchased a replacement V4073A from Screwfix which turned out to be faulty. When switching to DHW mode the valve would open 2 seconds after the pump started, causing the water to hammer. As it was winter at the time and the valve was otherwise functional, I decided to put up with the hammer until I next drained the system. Incidentally, the valve was made in Canada. Fast forward to May 2016. I drained the system in order to move a radiator and I took the opportunity to fit another replacement V4073A (this time made in the EU). I’m pleased to report this valve works perfectly and I expect it to give another 25 years' faultless service.
