Dual margin priority circuit for increased steering capacity

A dual pressure margin priority circuit that controls flow from a hydraulic pump to steering valve inlets and to low priority function inlets, the dual pressure margin priority circuit comprising:

• a steering pressure compensation valve with an inlet port and an outlet port, the inlet port hydraulically coupled to the pump and the outlet port hydraulically coupled to the steering valve inlets;
• a load sense feed orifice with an inlet port and an outlet port, the inlet port of the load sense feed orifice hydraulically coupled to the outlet port of the steering pressure compensation valve to provide a steering valve dynamic load sense pressure;
• a load sense cutoff valve with a first inlet port and an outlet port, the first inlet port of the load sense cutoff valve hydraulically coupled to the outlet port of the load sense feed orifice;
• a priority valve with an inlet port and an outlet port, the inlet port of the priority valve hydraulically coupled to the pump and the outlet port of the priority valve hydraulically coupled to the low priority function inlets;
• wherein the load sense cutoff valve controls flow from the pump to the low priority function inlets through the priority valve based on the steering valve dynamic load sense pressure at the first inlet port of the load sense cutoff valve.
