1995 cat 938F hydraulic control valve

Hello, I may need a control valve for my 1995 938f. Machine has forks on it and sometimes with a load it will drop just a bit over time. Does anyone know if this is the symptom for a bad control valve and if so where can I get a new or rebuilt unit? Thank You

    I would look to internal leakage in the tilt cylinders at the packing. Also, look at the relief valves bypassing. Simple flow tests will show the guilty party.
