This 4/3 directional control valve with an integrated blocking valve regulates the flow and direction of hydraulic fluid within the rake's hydraulic system. It directs oil to the actuators that raise, lower, or fold the implement's working sections, and the blocking valve locks the circuit in a neutral position to prevent drift when the function is not commanded. A worn internal spool or seal can cause internal leakage, leading to slow or incomplete movement of the rake arms and unintended settling of the implement. The manufacturer's original valve matches the housing's bore tolerance and spool clearance, which is necessary to maintain the correct pilot pressure for the blocking function.
