Horstmann Z222 2-Port Motorised Valve is rated 3.7 out of 5 by 10.
Rated 5 out of 5 by from Lasted 17 years Just had to replace one of these, which I installed 17 years ago. Pretty impressive given it controls the hot water, so it used twice a day every day for 17 years....

Rated 5 out of 5 by from Good value Only wanted the top - the original lasted 5 years - a replacement motor fitted only lasted 2. Existing valve body was sound with no leaks and freely moving paddle so fitting was minutes

Rated 2 out of 5 by from new model trouble I fitted two Horstmann Z222 a couple of years ago and was happy with their performance. Now one of the actuators broke (shouldn't this last a little longer?), so I thought I'd be smart and just buy a replacement actuator. Which I couldn't get. So I thought I am still smart and just buy another Horstmann Z222, just to take the actuator off that one and replace the broken one. Well, that didn't work. Despite using *the same model name*, Horstmann replaced the design by something completely incompatible with the older one. This is not good practice.

Rated 4 out of 5 by from Replaced an older valve I used this valve to replace an older model Horstmann which had a push button removable body, unfortunately they are not a straight body swop you have to change the mechanical part as well but at least the gland nuts and olives were compatable so it only took a few minutes.

Rated 4 out of 5 by from Changed Design One of the really irritating things that manufactures do is to change the fundamental design. In this case I fitted three of the previous design valves three years ago of which two have failed. And there lies the problem. There is nothing wrong with the valve body, only the solenoid unit. But, because the design has changed I have to replace the entire valve block and actuator. Putting that aside, these are fairly reasonably priced units and the one I fitted 12 months ago is working well. They are quiet in use and are neat and compact. As for reliability, I can only say that the previous model seemed to last about three years so the new one - this version - should be better.
