Well, we call them two different things, but essentially they are the same valve, just with vastly different spring rates. And a relief valve should be suitably sized to take full flow of any circuit that it’s fitted to, in the event of a ‘dead end’ it needs to take all the flow.
They are not the same though. A check valve is to prevent flow in the wrong direction a relief valve is to bleed off excess pressure

I should have said ‘we call them two different names and use them for two different purposes, but essentially they are the same valve’
They are both spring loaded one way valves.

do it as well as you can,but learn to do it better
seen that done before recently, 'cept on the cat head, not the root ...... the capacity of that machine may well be structural and not stability at a given radius .... looking at the deflection on that I'd guess he was well beyond the design limits of that boom .. that really is a lap of the Gods exercise ... would not be surprised in the slightest if that did not end well :oops::rolleyes:

Maybe you can find some details from this part number? View attachment 35553
thank you James .... and @Gecko for the further info. :cool:
been in search of a certain item today I was pretty sure I had ......

only issue is the 27 x 2mm on the one end .... gonna have to find an adaptor/boss to up it to 1"BSP :( . .... or buy a n other 1" BSP check valve like James's :rolleyes: this un's even got a 1/4" BSP side port, could pop a gauge into if I wanted ;):giggle:

forgot to say, I will measure what it cracks at and the pressure required for full open .... gave it a prod today and it's got a reasonable spring in it :rolleyes:

Have you already got the spool block?
I’ve had to do both standard valve with taking a 1/4” sensing line from each service back to the pump with a mess of shuttle valves and the proper load sensing valve block with single load sens line back to pump. Always been kawasaki pumps up the valves have been danfoss.
I have sussed the pump Mike ...
Sauer Danfoss series 45 - G frame - PC (pressure controlled) ...
so no direct LS as such ... pump sort of does it all ...

had a lot of head scratching about the one port on the body, 'til I determined exactly what the pump was and found the drawing and schematic for it and discovered it was the case drain ..... then it was a 'case' of deciding WTF it was connected originally ?.....

this came in several large bits from Mog and the only clues as to what went where, were the ports and unions/hoses ...
I'd taken plenty of pix for reference, as I dismembered it and as far as I can see (and it has me wondering a bit) is the case drain line was tee-ed into the feed line to the auxillary pump at the tank exit port. I'd presume this'd aid in drawing flow from the drain as the aux 'sucks' oil from the tank ...
there's a variety of BSP and metric fittings, so that too is a help in trying to suss things...
the line that was still connected at the tee was about the only union suitable to fit the case drain's adjustable metric elbow and was long enough to match the 2" bore main pump feed line from the tank. ...
any thoughts on the presumed suction effect likely??:unsure:
that said the drain should in theory be happy enough straight to tank which is vented so should have no pressure build up in it, to act against the case drain, which apparently runs at 0.5bar normally and has a max of 2 bar on cold start up.

been 'lashing up' some pipe runs direct back to tank, with what I have available, for now, so I can suss a shopping trip for the right sized ones and several other fittings I'm in need of for the fuel lines ....
would like to be able to bang some oil into it, .. try to get the electricals sorted and hooked up and see if I have it all correct, whether I can get it turning over and maybe even start the motor to see how it runs. :giggle:



got the fuel filter / primer pump bracket sorted and in place the other day
WP_20220517_12_51_47_Pro.jpg

and the unit ....
WP_20220517_13_51_15_Pro.jpg

need some fittings to finish tidying the line from it to the pump ... ;)
WP_20220517_13_51_21_Pro.jpg

had to juggle it for now .... bloody orf fitting on the pump and not going to risk trying to get it out .. it's VFT .. easier to plumb to it :)

main feed took some wrestling into spot .....:oops:
WP_20220519_15_52_51_Pro.jpg

and have since changed it too, to get a better run .. took some persuading ... pretty tight in there now :(
WP_20220520_17_43_52_Pro.jpg

output lashed into tank ... need a 1" M/F 90 to replace all the jumble

the 2" feed wrestling was a 'big spanner day'
WP_20220519_15_38_50_Pro.jpg


temp aux pump feed ...
WP_20220519_16_32_42_Pro.jpg

and this is that case drain port ... 's a big un ... metric equiv of 1/2"
WP_20220519_17_28_12_Pro.jpg

aux pump out, temp pipe to tank flying over it
WP_20220519_17_45_19_Pro.jpg

and in ........
again need and 1"F - 1/2" M adapter to lose the jumble, or even a 1.5"M - 1/2" M ... but that said, depends whether the case drain is gonna end up here .. so'll need a M/M/F 1/2" tee too to again lose the jumble
WP_20220520_19_21_27_Pro.jpg

if that case drain does need to go in the aux feed from tank .. this lot'd need some trimming down to a single F/M/M 1/2" tee

can never keep enough spare fittings in hand :rolleyes: ... at least gives me an idea of HTF to achieve this for now

shopping list 😁 .... well one of 'em anyway .... few other bits required too

getting ear ache off Pam to get on with her sister's gates :(...... so needed to clear the bench:rolleyes:

until I can get everything on board this, (oil, fuel, battery, etc., etc.) I can't establish a CoG to fit a lift point cradle, so had to improvise old skool .. and didn't want to squash/catch anything ... so

just the odd one or two details astray :(

WP_20220521_16_14_47_Pro.jpg

I did suggest assembling it all on a beam, digging a trench across his drive entrance .. bit of conc. in the bottom, stand the whole assembly on a couple of level shims .. couple of fixings and flood the trench with concrete .:giggle::cool:😍
was well up for it (y):giggle: 'til he remembered he's got a gas main, power cable and BT line in the way, in the drive :cry:... so 's gonna have to be old skool post planting :(

WP_20220521_17_02_17_Pro.jpg

required design is in need of 16 of these ...

used to roll them up on the old D, S & G lathe on a mandrel, 20ft lengths at a time and slit 'em into rings ... the Harrison ought to do an equally good job :giggle:
