Abstract: A system for controlling the stroke of an air-operated double diaphragm pump 12 includes a first control valve 30 and a second control valve 34 disposed in parallel within a drive air outlet conduit 28. The first flow control valve 30 has a first air flow capacity and the second flow control valve 34 has a second air flow capacity which is less than about 50% of the first air flow capacity.
