What it is

The ZA3/679-3 is a three-port diverter valve manufactured by Drayton Controls. It is a motorised valve used in domestic heating systems to direct heated water between the central heating circuit and the hot water cylinder according to demand. This version has 22mm connections and a three-wire electrical configuration.

Before you order

  • Confirm the existing valve carries the ZA3/679-3 marking, or that the system requires a three-port diverter valve of this type.
  • Check the pipework connection size is 22mm before ordering.
  • Verify the wiring arrangement of the installation matches a three-wire configuration.
  • Check the valve body and actuator mounting details against the unit being replaced.
