The Honeywell V4073A three port, mid position, spring return valve, is a masterpiece of clever engineering. It manages to move to one of three positions using only a cheap non-reversible AC motor, a spring, a couple of micro-switches, a resistor and a diode, and act as a relay for the boiler into the bargain!
INSTALLATION INSTRUCTIONS V4073A Motorised MidINSTRUCTIONS V4073A Motorised Mid-Position Valve Application The V4073A valve has been designed to control the flow of water in a small bore domestic central heating system where both radiator and hot water cylinder circulation are pumped. It is typically suited for systems up to 90,000 Btu/h (26 KW). Specifications Voltage: 230-240V ~ 50Hz
