Summary:

For a number of years, load-sensing systems have been increasingly used in mobile fluid applications, especially mobile cranes.The high energy saving potential of load-sensing systems is a special advantage; this system type decreases the pressure level of a pump to a value that corresponds to the actuator level. When the configuration includes a variable pump, a decrease in pump flow corresponding to the demand of the load will be a further advantage. Control of a load-sensing system can be enhanced by compensated valves to handle several loads.The paper at hand deals with the theories describing the steady state and dynamic characteristics of load-sensing systems with compensated valves and a variable pump. Two kinds of pressure compensated valves are discussed, the conventional and an interesting alternative with relocated compensators, physically positioned on the outlet side of the control valve instead of the inlet side
