How Does A Hydraulic Priority Valve Work?

A hydraulic priority valve, also known as a flow divider or flow combiner, is a component used in hydraulic systems to allocate priority flow to specific circuits or actuators. Its primary function is to ensure that a predetermined amount of hydraulic fluid is supplied to a high-priority circuit or actuator before distributing the remaining flow to lower-priority circuits. Let’s explore how a hydraulic priority valve works:

1. Valve Configuration:
   • A hydraulic priority valve typically consists of a valve body, a spool, and various ports for fluid inlet and outlet.
2. Flow Regulation:
   • The priority valve receives hydraulic fluid from the main pump or power source.
   • It regulates fluid flow based on the system’s specific requirements.
3. Priority Port:
   • The valve designates one or more ports as the priority port(s) where high-priority circuits or actuators are connected.
   • These priority ports receive the initial flow allocation before the remaining flow is distributed to other ports.
4. Spool Position:
   • The position of the spool within the valve determines the flow distribution between the priority and secondary circuits.
   • When the spool is in a neutral or centered position, the flow is blocked or restricted to all ports.
5. Priority Flow Allocation:
   • As hydraulic fluid enters the valve, it first reaches the priority port(s).
   • The spool is designed to provide a predetermined flow rate to the high-priority circuit(s) connected to these ports.
6. Remaining Flow Distribution:
   • After the priority flow is allocated, the excess or remaining flow is diverted to the secondary ports connected to lower-priority circuits or actuators.
   • The spool position allows the fluid to flow freely to these secondary circuits, ensuring they receive an adequate supply.
7. Pressure Compensation:
   • Hydraulic priority valves often incorporate pressure compensation mechanisms to maintain consistent flow rates regardless of load variations.
   • These mechanisms adjust the spool position based on the pressure differential between the priority and secondary circuits.
