This hydraulic valve controls the flow of oil in the hydraulic circuit of the baler. It is located in the system between the pump output and the actuator it serves, directing fluid pressure to perform a specific machine function. A valve that sticks or leaks internally will cause slow or incomplete actuator movement, reducing baling consistency. The manufacturer machines the valve body and spool to the same clearance as the original assembly, which maintains the designed internal leakage rate and response time.
