Thanks, i kept get getting Ansung links but no match on the number. Anything strike you as odd in that picture of the loader valve? Dan

In theory. I dont but have any catalog data for comparison but there will be some leakage. Dan

I was hoping to see some plumbing. Which spool do you have connected to the boom cylinders? Which ports are P, T, and PB? Dan

The "standard" for 3rd function is a D03 (CETOP 3/ NG6) industrial valve. They are spool type directional control valves with electromagnetic spool positioners. Dan

Matter of personsl preference and how you intend to instsll it I think.

I think that strategy requires a lot more testing than a $50 Karl Fischer titration. Dan

[ That is a performance requirement targeting stabilithy of the formulation in the presence of water. Virgin oil is bench tested by mixing 1% by volume of water with the oil, agitationg it, allowing it to stand, agitating again. and filtering it to collect any solids or emulsifcation suspended...

If its milky or cloudy its contamibated. Clear is good to go. Dan

There should be no water in a sealed pail of hydraulic oil. Your water intrusion is coming from some other source. Flush until its gone. Dan

Spool type directional control valves do not have "seals" and rely on the close sliding clearance between spool and valve body for the fluid seal. That is never leak tight and only gets worse with usage. You also need to remember there is a difference between pressure tight and fluid tight. You...

Exactly but it would be nice to know s bit about the loader. I have been assuming a Kubota loader valve. In any event poease take a pictire of the connections on the valve so we have cc a common reference. Dan

I think you are looking for a scape goat. The P80 on my tractor is made in Bulgaria by Badestnost, a well known European OEM. Their catalog description is quite extensve and detailed https://hydraulic-vlv.com/files/mf/products/16_file.pdf Spool leakage is claimed to be 6 cc/min @ 100 BAR and...

That is not a kubota model number so another mystery. The OEM loader is an LA703. Any other identification on the loader like a data plate?

It appears you are trying to build a single tandem center DA directional control valve from those two 6 port devices. Where does the stack go in the neutral circuit of the tractor and how does it control a DA cylinder? One more time - please diagram the circuit. Here is a start - your two...

That pucture looks like a diverter. If so there is no directional control function, power beyond or neutral circuit.. Please diagram your circuit. Dan
