About this deal

Used primarily in larger properties for zoning, Drayton's 2 port, diverter and mid-position valves are available in 22mm and 28mm. Yes I know in some systems the boiler is controlled by a micro switch in the valve actuator(s) indicating that a valve is open and heat is needed. By far the most failure prone part of my entire system - which is why I have now switched it over to a momo. This is due to unprecedented demand on their services due to several factors, including general Christmas demand.

p>The Drayton ZA5 is a highly efficient 2 Port Zone Valve designed for controlling the flow of water in domestic central heating systems. With careful disassembling and fettling you can re-attach the spring by hooking it through the baseplate hole.

I've had one of my two Drayton Za5 valves micro switches stick on me yet again, this time resulting in the HW permanently stuck on.

Engineered for ease of installation and maintenance, the ZA5 zone valve ensures precise control of water circulation. If you are replacing look at the possibility of installing momo actuators, no springs involved and no highly stressed mechanical components, designed to jam or break.

Yes, I do keep a second momo to hand, ready to install, but so far I have not needed to make use of the spare momo. Could replacing the actuator only fix the problem or would you recommend to replace the entire combination (actuator + valve)?

If you can remove the actuator and control the flow by manually rotating the shaft, then it will be the actuator only.
