The Honeywell V4073A motorised diverter valve with 28 mm compression connections controls the flow of water in domestic central heating systems where both radiator and hot water cylinder circuits are pumped. This mid-position diverter valve should be used in conjunction with a room thermostat and a cylinder thermostat for full temperature control of a conventional, fully pumped central heating installation. It is designed mainly for small-to-medium-sized installations.
