Drayton 22mm Zone Valve ZA5/679-2
This valve is used across a wide range of heating applications from central heating to hot water separation through to underfloor heating, it is sometimes called a 2 port valve and is always controlled via a room style thermostat. The valve in its basic function opens and closes and allows water to flow when the valve is open and stops the flow when the valve is closed. It is always found in S plan central heating systems but is also used in other types of central heating setups such as C plans. The valve is made up of a motor and microswitches that in turn send a 240V feed out to the controls on a central heating system.
