: type of fittings on Danffoss orbital valve (full hydro) KrustyKruiser 09-12-2002, 03:18 PM I have the box in front of me, all four ports are 3/4 inch strait thread, and i am guessing that i need to use o ring type fittings on the orbital valve, Before i order up anything i just want to check with someone to make sure that is the right thing. Ian- Ultim8kaos 09-12-2002, 03:24 PM Ian, yes you will need the o-ring straight type fittings. Depending on your hose routing you may want 2 tall and 2 short fittings to clear each other when installing. My Char-Lyn used #8 straight fittings and I used 90* fittings and had to use tall and short due to the close grouping of the ports. :D Old Scout 09-12-2002, 03:44 PM What about using JIC fittings? dirtrod 09-12-2002, 05:05 PM Originally posted by Old Scout What about using JIC fittings? I think he needs o-ring to J.I.C. adapters (37 deg.) flare, probably 1/2" o-ring X 3/8" JIC. btw...JIC stands for "joint industry council" ...I bet 90 % of the guys selling the stuff don't know that one, ...that tidbit is good for a substantial discount if used properly. ;) BillaVista 09-12-2002, 06:50 PM Common hydraulic fittings are: NPT (National Pipe Thread) - tapered thread ORB (O Ring Boss) - O ring seals against a machined seat in port JIC (37* flare) - flare seats against opposite flare in port. I guess you need ORB or JIC, and you should be able to tell by seeing if the ports have the opposite flare or machined O ring seat BillaVista 09-12-2002, 06:52 PM You can also tell by, 3/4" JIC is 12 TPI 3/4" ORB is 16 TPI Old Scout 09-12-2002, 06:58 PM Originally posted by BillaVista Common hydraulic fittings are: NPT (National Pipe Thread) - tapered thread ORB (O Ring Boss) - O ring seals against a machined seat in port JIC (37* flare) - flare seats against opposite flare in port.

Station 09-12-2002, 07:57 PM DanFoss valves in the size that you would be using on a wheeler have 3/4"-16tpi O-ring ports. Sean KrustyKruiser 09-12-2002, 08:08 PM Thanks guys i am on top of that one, One more though What size line do most people run, I am going to make the box match the ram with 3/8 npt, but shoud i run 3/8 hose, or is that too big? brainless 09-12-2002, 08:54 PM ian -10 or -12 to feed the pump , -8 is what i use on all the rest of the hydraulic system .if you are using a lower volume & pressure pump you may want to use -6 from your orbit to the ram , but use -8 from the pump to the orbit and -8 for your return line . take your orbit to the local hydraulic supply and they will hook you up with what you need . btw jic comes in 37 degree and 45 degree taper seal i like to use reusable ends so trail repair is made easy and you dont need to have someone crimp the fittings . the only downside is the reuseable ends cost a little more BillaVista 09-13-2002, 12:43 PM What NO BSPP???? It's very common! I have no idea what I'm talking about, really!! I'm just quoting from a catologue in a vain atempt to sound more knoweldgable than I really am :flipoff2: That, and maybe to see if Dirtrod will jump all over me, he's been way to quiet lately .....and I'm left feeling all out of sorts! ;) | |
