The individual actuated inlet valves discharge to a common inlet of a solenoid operated flow control valve which in the de-energized state provides a high rate of discharge to one outlet and in the energized state diverts flow to a substantially lower rate of discharge outlet. The valve assembly employs only three solenoid operators which are mounted integrally in a common valve body.
