The circuit implementing remote actuator control is a load sensing multi actuator system designed to manage parallel actuations using a variable displacement pump with flow compensator (Figure 1 on the left); each actuator is operated and controlled through a distribution block similar to the one shown in Figure 1 on the right. The core of the distribution block is represented by the proportional control valve 1. The metered power supplied to a hydraulic actuator corresponds to the degree of opening of the proportional valve. The elements labelled 2 are poppet lock check valves, and valve 3 introduces the local compensation control needed to manage the demands of multiple actuators, while the shuttle valve 4 selects the highest load-sensing piloting signal (LS) to be delivered to the pump. As shown by the functional description of the proportional control valve 1, the flow-rate modulation is of the meter- in type, which does not allow proper actuator control in the case of high overrunning loads. Under these particular operating conditions, the low pressure load-sensing signal selected by 4 reduces the pump displacement, hence the system reaction is opposite to the actual need of the remote actuator.
