Abstract
A mixer valve is shown which has two valves controllable by a mix controller to determine the ratio of fluid entering the mixer valve from two respective inputs, such as a hot fluid input and a cold fluid input, and a third valve controllable by a flow controller to determine the flow rate of fluid out of the mixer valve. Thus, the mixing proportion of the input fluids and the output flow rate are independently controllable. The mixer valve is suitable for incorporation into a mixer tap.
