Anyone able to help with hydraulic subplate/manifold design / build?

[Net30]

So I'm putting together a hydraulic unit. Its going to be... overbuilt? I guess just because if the parts I was able to acquire. Maybe a bit overcomplicated as well. So I got this load sense pressure compensated hydraulic pump and servo valve for dirt cheap and want to make use of them.

Figure I'll need a manifold with a ball valve that bleeds flow to port Y but prevents backflow(a OR b bleed to y only). I think they call it a shuttle valve. This will run back to pump to feed load sense line.

This subplate needs to fit my d05 solnoid. I guess the question is how to design one of these? I don't see alot of these with load sense lines and even less with blocked flow from a to b or b to a.

Load sensing pumps are not uncommon. I'd start with Sun Hydraulics and see if they have a module.

Y is an external drain port. Not sure what you are doing there. An A/B shuttle valve would give you a signal for load sensing control.

Ball valves are a poor choice for metering. A needle valve wod be a better choice. Are you using this as an office for the load sense?

Sketch up your circuit.

Sun has a broad line of cartridge valves and bodies. You might be able to make up what you need from of the shelf products.

If not a custom subplate/manifold is doable. Passage layout is the hard part from a design prospective.

Machining cleaning the passages after Machining and not leaving any shavings hanging up at intersecting holes is the challange.
