What it is

The Honeywell V4073A1088 is a three-port mid-position valve with 28mm connections, operating on a 230V supply. It is used in domestic heating systems to divert flow between the hot water cylinder and the central heating circuit, and to hold a mid-position that supplies both simultaneously. The valve is part of the Honeywell V4073A range of motorised diverter valves.

Before you order

  • Confirm the pipework connections are 28mm, as the valve body is sized to suit this pipe diameter.
  • Check the system wiring and controls are compatible with a 230V motorised valve.
  • Note the existing valve part number and range to confirm the correct V4073A variant is being ordered.
  • Confirm whether the valve body alone or a complete valve assembly is required for the installation.
