The Drayton ZA5 is a highly efficient 2 Port Zone Valve designed for controlling the flow of water in domestic central heating systems. If rotating the shaft doesn't effect flow (or if the shaft is stuck) then a whole valve will be needed.Here you can find useful information, training modules and wiring diagrams to help with your day-to-day job. Could replacing the actuator only fix the problem or would you recommend to replace the entire combination (actuator + valve)?
