<p>A mixing valve (10) is provided for mixing together two liquids in varying proportions. A first liquid is supplied at a first inlet (20) and a second liquid is supplied at a second inlet (78). The first and second liquids are mixed together in a venturi passageway (37). The flow of the first liquid is controlled by a plunger valve (40) and the flow of the second liquid is controlled by a metering valve (90, 92). The mixing valve (10) is capable of being joined in series to other mixing valves, each of which, other than the first of the series, receives liquid from its adjacent valve.</p> |
