Loader valve GPM for 4455?

[Craig C]

Got a new to me Westendorf XTA 700 loader mounted on my
4455. Had the hoses to rear, which is useless. Going through
my collection of hydraulic valves and I have a 15gpm prince
stack valve that I can buy joystick cable connections to, or the
other option is to buy a 25 gpm monoblock valve which would
use different cable connections. This loader uses large
cylinders and I need plenty of flow. So my question is, will the
15gpm valve supply all the pump can give me through a
power beyond port or will I be restricting flow?

I think 15 gpm will be sufficient for normal farm loader use. I think 25 gpm valve will make it difficult for infinite control of loader hyd functions

I disagree, bigger will be faster. Think
tractor will flow 20 to 25 at power beyond.
Bigger will feather maybe better.

I didn't state larger gpm valve wouldn't cause loader to operate faster.
