Used in the load sensing system, the Priority Valve controls the oil flow to the power steering unit. The Priority Valve sends the oil to a general functioning part when steering is in neutral. During the steering, it sends the oil to the power steering unit promptly.
Hence, it is named “Priority Valve”.
 

Benefits with Priority Valve

* Using only one pump, both steering and actuating can be operated.
* The oil just as much as the steering system needs to operate is supplied to the PSU and the rest is supplied to the actuators.
* Even in the pressure fluctuation in the line of the steering, the steering is operated smoothly.
