Honeywell 22mm 3 Port Valve V4073A1039
The Mid Position Valve / 3 Port Valve has been designed to control the flow of water from the boiler through to the central heating system or to the hot water cylinder in domestic central heating systems. The valve is always controlled by thermostats (a room thermostat and a cylinder thermostat) which are normally supplied by time clocks. The valve is made up of a motor and microswitches that send 240V feeds out the boiler and or pumps.
