In household and heating appliances valves are used to:

 -          regulate the flow of water in
            the washing machines and
            dishwashers
 -          protect water heaters from
            the over pressure

 
Electromagnetic valves are used to regulate the water flow in washing machines and dishwashers.

VV 108 valves are used in storage water heaters to protect the device from over pressure.
