What it is

The ZA3/779-3 is a three port diverter valve manufactured by Drayton Controls, supplied with 28mm connections and a three wire configuration. It controls the routing of heating water between ports within a central heating and hot water system. The valve is identified by product code 27207.

Before you order

  • Confirm the pipework at the valve position is 28mm.
  • Check that the system calls for a three port diverter valve rather than a mid-position or two port valve.
  • Confirm the existing wiring arrangement is three wire and that the system controls suit it.
  • Where the existing valve is accessible, note its part number to confirm ZA3/779-3 is the correct unit.
