ABSTRACT:
A fluid flow control system having a control valve which maintains a constant output flow rate regardless of input flow pressure variations. Three such constant flow valves are disposed in parallel to common inlet and exhaust headers, and hydraulically detented pilot control valves are selectively actuated to vary exhaust flow from the system in discrete steps. A web arrangement in the exhaust header prevents interaction of velocity heads between the flows coming from the three constant flow valves.
