Incorporating a 5gpm valve into a 6.7gpm system?

[Groo]

an Eaton single spool monoblock valve kind-of fell into my lap.

I'd like to incorperate it into Dad's Kubota L2550dt w/BF400G loader somehow. Either as an attachment, like a 3pt. log splitter or a gripper for the bucket.

I'm wondering if there is an easy way around the flow differential without adding some sort of bypass valve.

what kind of system is it, Open or closed hydraulic system?

is the body of the valve capable of flowing more than the spool does to the circuit?

and depending on were one plumbs it in, you will most likely need a power beyond adaptor, it is a fitting that allows the high pressure, to pass through the valve and not out the return flow,

if I found the correct page it looks like the inlet and out let is "3/4-16 SAE Inlet and Return Ports". the work ports are " 9/16-18 SAE Work Ports" http://psifluidpower.ca/sites/psifluidpower.ca/files/media/product/309.pdf

which should be capable of handling the 6 gpm, the unit produces,

as many 6 gallon a min, valves have hoses of 3/8"

the only way to be sure, is to call the company and talk to some technical people and find out for sure,

The free valve will likely work perfectly with your system with no visible consequence. The valve flow rating is likely at some standard pressure drop through the valve but 6.7gpm will still flow through the 5 gpm valve, it will just have a little more friction loss doing so, working your system slightly harder. If you tried to run double the rated flow or more it'd probably give excess heat and performance issues on motors etc. but for an aux. service on a tractor it will be fine with no special attention. I'm assuming that you know about power beyond, open vs closed, and all the other stuff required to add the valve to the tractor, but in terms of the flow rate, I wouldn't worry about it.

Assuming you also have power steering that would have a priority valve you probably would never see any ill effect.
Besides would whatever you use the valve for ever demand full flow? Cylinders would not only a hydraulic motor at full PPM would need all flow.

The 5gpm is rated inlet flow, but it looks like the single section has quite a bit less pressure drop in neutral than the triple section valve. Extrapolating the curve looks like 6.7 gpm might be around 50 psid. That is acceptable I guess. Its not like Dad winds it out much either.

The power steering is optional and from another section of a tandem pump I believe. It is hard-plumbed in, so tying in would be difficult.

I'll probably look at doing the 3-pt log splitter, since it won't be on all the time. Adding a section to the loader, I'll probably want a bit more flow, and maybe an electric over hydraulic valve as well.
