I prefer ball lock kegs because they're easier to release pressure (PRV), smaller diameter (can fit more kegs in kegerator), eventhough they tend to be a little more expensive. Pin lock kegs will suffice , but I prefer the ball lock overall for performance. Spare parts are quite expensive, so I recommend sticking with one or the other.

i see that the pin lock kegs on midwest have PRV's. Is there a way to convert a lid to have a prv?

I think the difference is that ball locks have PRVs that you can open manually by pulling them up.  On pin locks it's more of a safety valve that releases when pressure builds too high.

Of course, since I don't have any pin locks I don't know for certain, but that's what the internets tell me.

I'd personally be wary of drilling through a lid, but I suppose you could rig something.  Wouldn't it be easier just to release pressure on the gas side?

I know that you could just depress the poppet on the gas side, but isn't that a PRV?

I just recently bought three ball lock corneys and a kit to build a two tap kegerator. I built and learned a lot along the way. I did not know about size dif between ball and pin but got lucky and bought the skinny ball locks. With some cutting and carving I got two to fit in a 4.4cf magic chef

Yes, photo #4 shows a pressure relief valve.  I've seen them on some pin lock kegs, but not very often and usually they had been modified to fit or the whole cage had come from a ball lock keg.

Alright!  A topic I can really get into!

I've been playing pinball since I had to stand on a milk crate to reach the bumper buttons (WAY before Tommy)

My favorite machine?  Bally's Fireball!!!  Hands down. 

Cornelius kegs?  I have a s***load of those.  I use them to store low wines in, for the most part these days.  A couple of C-kegs full of low wines at 40% is the perfect charge for a spirit run on a sanke keg boiler.




I serve my homebrew from six-tels.  sanke connections s*** all over ball and pin(head)lock connections.

Many reconditioned pin locks have had their lids replaced or modified with a manual PRV. I'm not sure you can do that yourself - I don't even know where you'd buy the PRV parts. You can buy replacement lids, but I think they're around $15. Starts to get into 'Why am I saving money on a used keg?' territory.

So, long story short, looks like those are good buys for the cost.

thanks.
