Priority Valve (

Disclosed is a hydraulic system for a machine having a pump, a steering circuit and first and second hydraulic implements, e.g., a hydraulic loader and a backhoe, powered by first and second valve sections, respectively. In the improvement, the system includes a priority valve receiving fluid from the pump and configured for movement between a first position and a second position. · The pressure control valve, also called the priority valve is located in front of the instrument panel. The purpose of the pressure control valve is to insure that pressure is maintained to the steering valve and the brake valve, for safety requirements. Also, I don't believe that the rockshaft valve would cut off flow to the SCV. · The priority valve on a similar JD is on the inside of the right frame, just follow the high pressure line from the pump, it goes to the priority valve, then lines go from there to the loader valve, backhoe valve, etc.
