Issue removing coupler/valve from (Australian) keg

Post by kronicd »

I've acquired a keg with "lion nathans" branding and I'm having a bit of trouble removing the coupling/valve.

I managed to remove the black seal, the spring and a couple of pieces of metal that sat over the spring, however the large metal thing shown in the picture (the coupler?) doesn't seem to want to budge. I've tried putting some metal in the hole and hitting it with a hammer to try and get it to turn as well was prying it upwards with the back of a hammer, both to no avail.

Any assistance would really help!

on regular kegs the inside valve is turned and pops out, i have never see a keg like that but, the inside valve stem should be able to come out try rotating it and freeing it from the ridge thats holding it. the coupler stays put the actual valve is inside. like i said i havent came across a keg like that. top veiw pic mite help.

That is what it looks like when it is in tact and here is a picture of what it currently looks like.

The valve seems to turn freely but cannot be removed, it seems like there are three prongs which stick out past the inside of the coupler.

Sorry this hasn't been resolved yet. This set-up is completely foreign to me... my only guess w/o putting hands on it is that you have rotate the body of the valve to a certain point and then it comes out. If you've been beating and banging on it, there may be some burrs, etc. keeping it from exiting easily. I'm surprised some of our Aussie members haven't helped out their mate :) :) Try PMing hookline, punkin, blanikdog, etc. Good luck.

Not positive but looks like a German "flat top". and I thank the flange screws off (thus the hole for spanner)

I'd help out if knew what the fuck it was, but I've never seen one before. Pretty well every keg over here is a Sankey.

.au is the Australian URL suffix. But not sure what you mean, where is the .au you refer to?

EDIT: Just spotted what you were referring to. :oops: :roll:

No luck yet, I'll have a look around and see if this is the standard type of keg here, if there is another kind I'll grab that.

Otherwise I'll just cut around it!

I looked up the Micro Matic web site. It's an 'A' series valve. Used in Europe and Aus. Could not find anything on taking it apart though.

It looks as if you hold the outter part with the single small hole stationary with a spanner then the spanner would have a hole in the center of it and another tool or part of that tool reaches down into the coupler and unscrews the valve inside it like the valve stem on a tire.

I thank the "flange" screws off if you look on the "neck" you can see a mark where it comes apart?

I see the seam you're talking about Dundr, but if it just turns freely when you turn it and it doesn't unscrew then maybe there's a locking mechanism in the valve itself. I just looked at it for a minute and reread what was done already to no avail and the inside valve is flat on 2 sides like a valve stem in a car or other tire. So I'm wondering if that comes out and relieves a wedge type holder to allow the flange to come out of the keg then. Either way with the seam there there's not going to be a flange to attach a sanke adapter and triclover clamp to so he may end up cutting the top and using a bowl anyway so removing the flange would be fruitless.

Think you said the flange turns free? If so, I bet there is a notch in the inner part that matches the hole in the flange. Turn the flange until it is aligned then a pin on the wrench drops in. Looking at that pic, it is standard right hand thread.
If I'm right, you can make a wrench by using a piece of strap with 2 bolts. One locks the flange, the other into the well.

I was searching for a post from a fellow who's not active here anymore... bujapat... A fine fellow, he had a very simple potstill design that I wanted to show someone. I noticed that he had taken apart this same type of keg.

so I wrote him an email... Maybe he will pop in and explain.

his simple still...

He has a nice distilling site in french too...

the head turns anti clockwise you need to tool to do it like this pic
the thread will be glued (lock tight) so getting it moving in the first place will be tough

I have a keg like this (Tooheys brewery) dosen't have the hole in the coupling though. I used a pipe wrench to screw the coupling off (anti clockwise)

I just did one of these. Firstly de-pressurise the keg by carefully unscrewing it slightly with a large Stilzen. You can aslo loosen it with a hammer and cold-chisel if you don't want to re-use the top, even then the top can be re-used if you slide the fitting on from the side opposite the chisel notch you make. Get a small good quality flat-blade screwdriver and remove the rubber washer, outside edge first. Again if you are careful, this can be re-used. Now use 2 small screwdrivers to turn the inner part clockwise. Poke then into the holes in it opposite each other, lift upwards and turn(clockwise) . It will unlock from the lugs and drop down into the keg. Now unscrew the top, leaving the spear behind. Once the top is out the spear is tilted to remove past the lug on the retainer.
As I want to use mine for beer as well, I carefully cut the locking lug off-making sure to leave the tab the same length as the others. Re-assembled minus the spring, then screwed the spring back up over the bottom tab-plate- a bit of grunting- but now I can screw the assembly in and out in one piece for beer filling !!
