Claim:
1. A multi-chemical dispensing device comprising: a flow selector valve comprising a concentrate intake port, a first concentrate outflow port and a second concentrate outflow port, said flow selector valve further comprising a valve housing and a valve insert movably mounted within said valve housing, said valve insert including a flow chamber defined partially by a dilution member, said flow chamber being in fluid communication with said concentrate intake port, and wherein said dilution member comprises one or more first orifices and one or more second orifices in fluid communication with said flow chamber wherein each of said first orifice and said second orifice have an opening area that allows a fluid flow therethrough; a first proportioner for discharging a mixture of concentrate and water at a first dilution ratio, said first proportioner in fluid communication with said first concentrate outflow port and in fluid communication with a first motive fluid supply wherein motive fluid is provided at a known first flow rate; and a second proportioner for discharging a mixture of concentrate and water at a second dilution ratio, said second proportioner in fluid communication with said second concentrate outflow port and in fluid communication with a second motive fluid supply wherein motive fluid is provided at a known second flow rate; wherein said valve insert is movable to one or more dilution positions wherein at each dilution position one of said first orifices aligns with said first concentrate outflow port or one of said second orifices align with said second outflow port to allow fluid flow from flow chamber into at least one of said outflow ports for supplying a flow of concentrate to one of said first or second proportioners.
