This unit is a direct acting, screw in cartridge style, spool type, priority on demand pressure compensated flow control element. This unit is used to provide a load sense steering first with the priority flow when steering demands the flow and the amount it requires before any other function in the system. When the steering or any other priority functions are satisfied, only then the excess flow is diverted to the auxiliary port for other functions.

When the steering wheel is turned, the flow from port 3 is distributed to the priority port 4 when the system calls for it. The remaining flow is available to the rest of the working hydraulic system thru the excess port 2. The distribution is controlled by the load sense signal to port  from the steering unit, so the flow to the steering unit is always determined by the actual steering rate.
