Hydraulic valves

I have 1991 Ford F450 with a Telsta A28D bucket or lift. My question is a kind of generic one. All the Hydraulics work. They are 12V electric to a series of 4 valves (rotation, lift, extend and bucket retract). Each works off 12V toggle switches to what I think is a solenoid that opens up the valves and applies pressure and / or relives pressure. I think this is pretty standard

My concern is the motion ‘jerks’ when starting. I think there is an adjustment to slow down the actuation and smooth out the start and stop.

Question: Ho does one feather in or adjust these? Is there a rheostat, or a pressure relief valve? I think there is a standard way to adjust this, but I don’t know what it is
