Sizing a 3rd Function Valve for Flow

[kb12610]

It can be rated at 6.6GPM but at what pressure drop or loss?

The #4 is too small. Look up a hydraulic nomograph chart on google, very easy to use. Like this one

I think the valve the OP is looking at is a "diverter" valve, not a true 3rd function solenoid valve (this is where links to the products your asking about helps). Since your only "diverting" the dump/curl circuit, I think it's fine. I would not put a small valve like that in the the main flow from the pump.

But is it in an open center hydraulic system?
And where is the 3rd function in the circuit?

Open center and after the control valve to split the curl.

Are the in and out #4 also or just the work ports? If just the work ports it well ok. Put a link to the valve you are looking at.
