My question is can the actuator be replaced with a different more reliable model without changing the valve itself?

The CD with the software for the Diagnostics for the Vaillant boiler Vrdialog 8102 is very out of date. We currently have a Drayton ZA5/679-3 and there is no longer correct switching between the 2 exit valves (boiler water + heating water). There are other possible reasons for loss of supply to the momo as well as potential for internal failures of the momo. Used primarily in larger properties for zoning, Drayton's 2 port, diverter and mid-position valves are available in 22mm and 28mm.Actuators are devices used to control and automate the movement of valves or dampers in heating, ventilation, and air conditioning (HVAC) systems.

Engineered for ease of installation and maintenance, the ZA5 zone valve ensures precise control of water circulation. By far the most failure prone part of my entire system - which is why I have now switched it over to a momo.You mentioned that if the momo lost power, then also would the boiler - that is only true sometimes, but it cannot be guaranteed. p>The Drayton ZA5 is a highly efficient 2 Port Zone Valve designed for controlling the flow of water in domestic central heating systems. But with so many different controls on the market, it can be confusing to understand exactly what these products do, and which will be the best for your home. If the MoMo does not close because the power has failed then the boiler will also have lost power and shut down.
