The priority valves from M+S Hydraulic are available from HAW for the distribution and trace of the hydraulic flow from the supply pump of the hydraulic system to the hydraulic components which control and run the vehicle.
The Priority Valves are used only with the HKUS.../5 (T) hydrostatic steering units. Priority valves with dynamic signal work in a system with dynamic hydrostatic steering units type HKUS.../5D (5DT). The Priority Valves PRT...160 have built-in pilot pressure relief valve, protects the steering unit against excess pressure.
When connected, the steering unit and the priority valve represent a sophisticated hydraulic tracing system that controls the flow in both main pipelines of the hydraulic system (the working and control one) at any time of its operation.
