ABSTRACT:
There is provided a combined step and proportional integral flow control valve system having a fluid control valve for controlling flow of fluid into a water stream, a valve motor in operative engagement with the valve for setting the value, a motor control unit having an output connected to the valve motor, and an input responsive to at least one of a first or a second input signal, and wherein the second input signal is a step signal, and the first input signal is a proportional integral control signal. The water stream is a composite of at least one feed stream, a pump is driving the feed stream wherein the water pump includes apparatus for generating the step signal, indicative of the pump being in one of an on or off state. The control valve system includes a flow meter in the water or waste water stream for generating the proportional integral signal as being proportional with the water flow or volume in the water stream.
