ABSTRACT:
A fluid flow control valve includes a body having an inlet and two outlets. A metering control element is slidable in the body to regulate flow through one of the outlets. A combined spill and throttle control element is slidable within the metering element so as simultaneously to control metered flow between the inlet and the one outlet, and spill flow between the inlet and the other outlet. Both of the control elements are responsive to respective servo pressure signals.
