Could be danfoss (vickers) 30542-6C...
It's on a 650 FEL on a 186D looking for the spec sheet or information on relief valve.
Doesn't have a conventional relief valve.

I don't have full understanding of companys but I think you will find one of the two or both are the manufacturer of your valve. Cessna - Eaton Hydraulics - Precision Fluid Power

This is just the valve casting, not complete valve. 30542-6C | Danfoss PowerSource

So then where would it be? It's a Yanmar 186D..on the 3 point?

information plainly states set relief valve pressure 2000psi. Relief valve is on top right of first picture. Pressure can be adjusted with shims. Yes, your 3 point also has a relief valve.

Not so sure as it looks like a plug, rather than a relief valve, but can't hurt to unscrew the plug and find out.

Your photos don't look the same as the OEM loader valve on my YM186D. Could it be aftermarket?

It has always been my understanding that all loader control valves have relief valves. Maybe I'm wrong but do know the Eaton sight is showing a relief valve on the one that has been attached. I can't imagine using a loader without a relief valve. I cause my loader valve to relieve quite a bit when using my loader. Without one I am pretty confident my pump would be trash.

I agree, but looking at the literature and the picture of the valve, it appeared to be a plug. It could be a shim relief under there. Being it is an older Yanmar, anything is possible. They could be depending on the tractor system relief, but you are probably right.

Mine is identical to that when attached to the tractor.
