The Danfoss HS3 22mm 3 port mid-position valve is used to direct central heating water from the boiler to either the radiators for heating or back round into the secondary heat exchanger to heat up the domestic hot water. A motorised ball-arm allows for positioning to supply only hot water, only central heating or both.
