Abstract
An antagonistic fluid control system, wherein the system may comprise multiple antagonistic pressure control valves operable with a single actuator, or multiple pressure control valves operable with respective antagonistic actuators. The pressure control valves are configured to provide functional and efficiency advantages, and operate together to provide several operating or valving states. A first valving state comprises an active valving state configured to actively control the movement of the load. A second valving state comprises an inactive actuation state, wherein either the return and pressure ports of one pressure control valve are closed, or only the return ports of one pressure control valve are opened, to allow the other pressure control valve to operate in an active valving state. A third valving state comprises a passive valving state, wherein the pressure control valves are operated in a slosh mode configured to allow the load to freely move or dangle. In this third passive valving state, or slosh mode, the return ports of the two pressure control valves are opened to allow fluid, and preferably local fluid, to shunt back and forth within the system.
