Forks drifting down

This is a 45RRTT high bay reach truck. Forks are drifting approx 5" in 5 mins. Its not leaking externally anywhere, which rules out the cylinders. Cylinders are displacement type cluster cylinders. I removed holding valve threaded into valve block and inspected visually. Seems OK. Removed return line at tank with forks raised and still no fluid. The forks are still drifting and I don;t know where the fluid i going? Any guesses??

Check the flow control valve. Raise the forks. Go to the hyd tank, take off ( carefully ) the little plastic hose that goes to the top of the tank at the return and see if there is a small flow of oil. If so the flow control valve is junk ( internally by-passing).

Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
