Zusammenfassung:	Load Compensated Valve A load responsive system including individual positive and negative load compensators, for control of positive or negative load and an external logic system for determination of whether the controlled load pressure is positive or negative. The deactivating valve deactivates the positive load compensator, when the negative load pressure exceeds a certain minimum predetermined level, preventing flow of fluid from the system pump to the system actuator controlling a negative load at a pressure higher than a certain predetermined level, and therefore preventing development of excessive pressure in the actuator, while also deactivating the negative load compensator below a certain minimum predetermined negative load pressure level and while the positive load is being controlled by the positive load compensator.
