This valve plate is a component in the hydraulic system of the host tractor. It sits within the control valve assembly, directing fluid flow between passages to actuate remote cylinders and motors. The plate's machined faces and port alignments determine the valve's spool timing and flow paths. A warped or worn plate causes internal leakage, reducing system pressure and causing sluggish implement response. As an original-manufacturer part, its surface finish and flatness match the valve body's mating face, which is required to maintain the correct clearance for the spool seals. On reinstallation, ensure the mating surfaces are clean and the valve body bolts are torqued to specification.
