 Hydraulic fitting threads

I'm working on a rear hydraulic setup for my 7800. The different threads for hydraulic fittings can drive you nuts. The prince valve I'm looking at has SAE #8 and SAE #10 ports. Im Familiar with STOR, JIC, and NPTF fittings. Does anyone know where I can get information on what SAE #'s refer to. Thanks

The numbers probably are DASH sizes and SAE would be a standard for the construction, threads etc. The link below has some information. The tables I have give thread size and type by DASH size but the specs are different for o-ring boss and o-ring flat face connectors. The complications never end in this buz.

Thanks, I think this helps. I'm sure I'll have a few left over fittings when this is done.

Yep, those Prince SV valves have SAE-8 work ports. I purchased SAE-8 to 3/8 NPT adaptors at a hydraulic shop and used 3/8 NPT for all other connections. 3/8 NPT fittings are readily available, even Kubota uses them. BTW, the threads on the tank return under the seat are 3/8 NPT.

Yep, I think I've got it. I'm sure I'll still have some fittings in stock when I'm done. Thanks again

Beagle: You may not be aware that there could be a valve issue. If the setup you're working on is fairly standard so that the return oil from the valve goes on to the 3ph or other valve then the valve should be power-beyond rated. If it isn't then you have to be sure that the 3ph is not raised with an appreciable load at the same time the valve is operated or the valve may be ruined. There's a decent chance the Prince valve is PB rated but it'd be good to be certain.

The set up I have planned would be: Power Beyond from the FEL to the inlet on the Aux Valve, Power Beyond from the Aux. Valve back to the Power Beyond on the tractor block. Both valves would exhaust with a tee to the return on the tractor. In other words, I would keep the regen. circuit in place with the aux valve in series with the FEL valve. Does this sound right to you? I believe by the time I get all the fittings to make this work, I'll have more left over that I started with. By the way, I was planning on a two spool set up for the aux., one would be a motoring spool to run a Hydraulic winch, the other would be a four-way for the top link. Anyone done this?

Beagle: If the valves you're using have two ports on the outlet section then they almost certainly have power-beyond capability. Some single return port valves are PB rated and some aren't. If you haven't ordered or seen them yet, it good to get valves that have flow ratings only slightly larger than the tractor's pump rating. A 20-gpm valve probably is a much larger hunk of iron then you'd want to put on a compact.

Your hook-up sounds right. Valve assemblies are connected in series--high pressure port on the tractor block to the inlet of the first; PB outlet to inlet of the next and PB outlet of the last back to the tractor's return port. I call the other port on the valve outlet section the tank (the ports often are stamped T and PB). Tank lines handle cylinder exhaust oil and go directly to the reservoir. Far as I know they can be combined with t-fittings.

I'm not really up on my motor stuff. I think of a valve that runs a reversing motor as an ordinary directional-control spooling-valve specialized only in having detents at both ends of the travel. They could be more specialized, but if that's the case then the idea of combining both control valves in one assembly is feasible. It's just a matter of finding a manufacturer that sells control valves sections with the needed features and ordering an assembly with the right valve sections. I do think you have to make sure that the motor has reversing capabilities though.

Tom, the Prince sectional valves I'm looking at are the SV series rated at 12 GPM. They have two options for the outlet section, I'll get the Power Beyond outlet. Size has been a concern, I sure don't want 20-gpm vlaves. Thanks for all the input, it's been a lot of help.

Happy if all my bumph helped. It's a way of returning a bit for all the stuff I've learned mostly from here.

You might look at other manufacturers if Prince doesn't have a valve section that's right for the motor. I'm thinking that if it's just detents then the valve could be used for most any direction control application. Another manufacturer might have different flow rating valves as well.

I don't know if the Prince valve is one of the types that can be used on either open or closed centre systems. If so, they tend to be supplied set up for closed centre use. A plug has to be removed to use them on open centered systems.
