What it is

The 2-WAY VALVE DVLV-A757JBKZ is a Worcester Bosch two-port valve intended for use in heat pump installations. It regulates water flow through the circuit by opening and closing the two-way port. Worcester Bosch lists the valve under part number 8738204468.

Signs this part needs replacing

  • The valve does not change position when the heat pump calls for flow.
  • The actuator runs or clicks but the valve spindle does not move.
  • The heat pump circuit stays cold or does not reach temperature despite a demand.
  • Water passes through the valve when it should be closed, or flow stops when it should be open.
  • Visible leaking or weeping from the valve body or spindle.

Before you order

  • Confirm the part number DVLV-A757JBKZ or 8738204468 on the existing valve or in the appliance documentation.
  • Check the appliance model plate to confirm the heat pump is a Worcester WAA OU 6.
  • Inspect whether the fault lies with the valve body or the actuator, as the two are separate components.
  • Note the pipework connections and valve orientation before removal.
