This example model shows how to move a load with a cylinder. The directional control valve is used to connect the cylinder ends with either the pump or tank depending on the command. The pressure relief valve limits system pressure by opening when the pressure has reached a certain threshold.

Fig. 1 shows how the system pressure is limited by the relief valve. Fig. 2 shows how the control valve opens and then closes. Fig. 3 shows how the cylinder moves when the control valve is opened.
