• The surface area in the load sense of the spool on the unloading spool is greater than the area a the pump discharge port. This area difference maintains the unloading spool seated against the pump housing when there is load sense signal present. The laod sense signal comes from the maximum pressure required to actuate any of the graders funstions.
• When the system is operating in the flow control mode, the flow control spool rises, alowing excess pump outlet flow to by- pass to the tank port based upon the pump flow required at the Grader valve. The flow control spool will maintain an approximately 300 psi pressure difference between the pump outlet pressure and the load sense signal returned from the grader control valve. This 300 psi pressure difference will assure that any flow required at the grader valve will be available.
• When the piston gets to the end of its stroke or finds a high resistance to flow through the grader valve., the result is an increase the load sense pressure. The maximum load sense pressure is limited by the load sense relief valve in the outlet section of the grader valve. The maximum load sense pressure specification is 2600 psi. which will result in the pump outlet pressure being 2900 psi, due to the 300 psi differential across the flow control spool.
