What it is

The Baxi Interpart 28mm 2 Port Valve is a two-port motorised valve with 28mm connections, listed under the Baxi Interpart spares range. It opens and closes a single circuit on demand from the appliance controls, directing water to the cylinder or the heating side as required. The valve is listed for use with Boss thermal stores and Gledhill Boilermate units.

Signs this part needs replacing

  • No flow to the cylinder or heating circuit despite a call for heat from the programmer or thermostat
  • Actuator motor runs but the valve spindle does not move, or the valve remains stuck in one position
  • Manual lever moves without resistance or fails to spring back
  • Water weeping from the valve body, spindle or connection nuts
  • Boiler fires and then shuts down shortly afterwards, or the pump runs on with no circuit opening

Before you order

  • Confirm the pipework at the valve position is 28mm, as the valve is a 28mm pattern
  • Confirm the existing valve is a two-port configuration and not a three-port mid-position or diverter valve
  • Check the appliance model against the fit list above before ordering
  • The line is catalogued as obsolete, so confirm availability before booking the job in
