Honeywell Home 3-Port Motorised
Mid Position Valve BSP
V4073A1062/U

The V4073A is a mid-positon motorised diverter valve with 1" threaded connections controls the flow of water in domestic central heating systems, where both radiator and hot water cylinder circuits are pumped. Suitable for small-to-medium sized installations. The valve should be used in conjunction with a room thermostat and cylinder thermostat for full temperature control of a conventional, fully pumped central heating installation.

  • It may be plumbed in at any angle but the flow must go into Port AB and must not be mounted so that the powerhead is below the horizontal level of the pipework
  • If fitted in a confined space, sufficient ventilation must be available to keep the valve within its ambient temperature range and access must be provided to remove the powerhead if necessary
  • 1in BSP Female fitting
  • Spring return action
