Boka still safety valve

[ulster_beef1]

Hello folks,

My still is nearing completion (pics to follow). I have read up on the forum regarding safety valves but I can't seem to get a full answer for my piece of mind.

I have a 54mm column which is vented at the top and is therefore 'fine'. However, I intend to run gin with a botanical bag/ container at the top of the column, which may clog up and result in pressure build up.

My column will be attached to a 20l stainless cooking pot. I intend to seal the lid with dough and held closed with crocodile clips or similar.

I believe a valve is best placed in the pot yes? Being a cooking pot and not a pressure cooker for example, there's no PSI rating. Therefore, how do I know what rating of valve to get? The dough may fail first but I want it as full proof as possible.

The above is a problem for me, as running a basic sugar wash won't cause any pressure but how much would a clogged bag create? A simple marble/ kettle valve could work but is that up to the job?

Basically I've read up on people's ideas but I haven't seen any indication of what PSI valve I should aim for.

Thanks for your help

You really don't want pressure building up at all... Where would you vent to...??? IF you go the pressure relief route you wouldn't want more then a 1 - 3 PSI relief valve and they can be tough to find and might be pricey... Perhaps rethinking you intentions would be a better option... You'd probably have a leak through your flour paste before a PRV tripped anyway... Heating with an open flame could prove disastrous...

Could always use a manometer vented to the outside.

Could always use a manometer vented to the outside.

Probably the best and cheapest solution...
