Honeywell 22mm Mid-Position Valve

Honeywell V4073A1039/U Mid-position Diverter Valve 22mm has been designed to control the flow of water in domestic central heating systems, where both radiator and hot water cylinder circuits are pumped. It is typically suited for small to medium sized installations. This should be used in conjunction with a room thermostat and cylinder thermostat to provide full temperature control of a conventional, fully pumped central heating installation.
