A fluid control system includes a directional control valve assembly adapted for use in either an open-center or a closed-center configuration. The system is capable of incorporating one or more control sections, each with a manual control valve and its own individually variable flow control mechanism. Each flow control mechanism is independently responsive to section load pressure, and is capable of controlling the flow rate delivered to its section when the control valve spool is biased to a full power position. Each section contains a kickout mechanism for returning the control valve spool to its neutral position at a predetermined pressure. |
