VICKERS FR1 20 F 0 /45.00

Fixed pressure-compensated valves are built specifically for that kind of problem. When system pressure fluctuates, an uncompensated valve lets flow vary right along with it, which causes erratic actuator speeds and added heat load. The FR1-20 holds flow steady regardless of pressure changes upstream or downstream, so your circuit stays consistent even when demand shifts. At 227 liters per minute flow rate and a 350 bar pressure rating, it has plenty of headroom for most refuse hauler hydraulic circuits.

This Vickers flow control valve handles up to 350 bar (5000 psi) and 350 L/min (92 USgpm), so it should do the job, assuming your system doesn't exceed those levels.
