Hydraulic Circuit with Load-Sensing Velocity Control

This example shows a circuit that is equipped with a load-sensing velocity regulator installed between the pump and directional valve. Unlike a conventional meter-in velocity control, the load-sensing device automatically adjusts output pressure of the pump in such a way that it equals the sum of the preset pressure drop across the pressure-compensated flow control valve and the pressure induced by load. The pilot-operated pressure-relief valve in the load-sensing block is built of the Poppet Valve and the Hydraulic Double-Acting Valve Actuator blocks.
