Slowing Down a Hydraulic Function

[SPYDERLK]

Ideally, I'd like to install an adjustable flow restrictor (either variable or on/off) but I don't know where in the circuit it should be installed.

My question is, should I do that on the supply side or the exhaust side?

I was thinking about something like this:

Buyers Flow Control Valve-1/4in. | Adjustable Flow Valves | Northern Tool + Equipment

Thanks,

The restrictor will have the most effect on the push side of the cylinder since more fluid flows there.

I did the same thing on both a Kubota B2400 and L4330. The valve you show is easy to install between the valve block and the quick disconnect. I restrict flow out of the base of boom cylinders back into the valve block.

However, your valve is not pressure compensated, which means that if the valve is closed enough to slow the fall with a heavy load, the booms will barely move when there is no weight on them (unless you force them down with pressure on the rod ends).

If you move one step up to a pressure compensated valve, the rate of flow (gpm) will be almost constant regardless of the load. That way, the booms will move down at about the same rate when loaded or light.

I see some Northern valves that are about $50 that appear to be pressure compensated, but one can't be sure just from looking. Perhaps Northern can give you more information. I got mine at the Parker Hannifin store and they were about $80 each, but worth it. Surplus Center had them at one time, but I have not looked lately.
