What valve do I need?

[ParkerFly]

In the process of reworking and adding to the hydraulics on a piece of equipment. I need a valve with two spools (to control 2 separate cylinders). Just one that is normally in neutral and you can push or pull to extend or retract the cylinder. No need for float. Can someone give me a suggestion on what I need? Thanks.

Need a little more info first. What is the GPM rating of the machine or pump you are using?

That's been a problem for me trying to find out. It has a belt driven pump off of the motor on it, but no markings or any info on it that I can find that shows what the GPM is. I figured to be on the safe side I should get a valve that will handle higher flows. Based on my experience with other hydraulic equipment and comparing it to the speed at which this system works, my best guess would be that it flows in the high teens at best and in reality probably lower than that.

I was looking at this one:

Directional Control Valves 220-522 Detailed Information

Am I headed in the right direction? This one is a little pricey, so I'm certainly open to lower priced ones but don't want to get too low on quality.

Yes, that is fine.

HERE is one rated for 10 GPM

HERE is one rated for 25

They have more options also... What size ports are on the pump-that may be a little clue as to the GPM rating.

I'll have to get a measurement on the ports, but best I can recall they are pretty large. I just know it seems slow operating a 4" cylinder when compared to skid loaders with flow in the high teens operating a 4" cylinder.
