Beer Line Flow Restrictors

[mobrien]

Well its dark and I don't have any lights - but I took a video of the comparison of a new keg pour with the restrictor wide open and then dialed back. I hope it shows that they do indeed work for me!

My lines are 50mm from keg to restrictor then 500mm from restrictor to tap.

Video Works for me.

Looks like the goods to me mobrien. Pictures tell a thousand words.

Would it be possible for you to post pics of how you have the lines setup.

Cheers,

I cant see much use for restrictors other than a bandaid fix for line length. Before outlaying the coin on restrictors look into balancing your system. So far I've never had a beer that wont pour properly from my keg fridge.

Just for reference:

4 mm line has 42kPa resistance per metre
5 mm line has 33kPa resistance per metre
6 mm line has 23kPa resistance per metre
8 mm line has 8kPa resistance per metre
10mm line has 2.5kPa resistance per metre

No probs - the lines are shown in detail in this thread:

see posts 56 - 58 especially.

You may see it as a band-aid - but I see it as a way of having the length of line needed to reach, with complete control of the flow. But horses for courses - I like my way, you like yours - at the end of the day, if it pours a good beer who cares how long the lines?!

I also have a balanced system, and I also think that 'resistance per metre' numbers are also dependent on the material used for the line. I've had experience with cheap line and its flexible and kinks easily, and good line which is still flexible enough, but harder plastic and kink free. I'm certain the two lines (same ID) would have significantly different inline resistance.

I think the simplest and best way to do it is just set the pressure for the right pour speed (regardless of line length), then when u drop a brew into a keg let it sit at that pressure for 1-2 weeks and its carbed up perfectly. If your inclined to want different amounts of carbonation for different styles, adjust the temperature to suit (eg warmer = less C02 disolved = flatter beer), the trade off (temp for carbonation) is usually within style anyway.

That said, if you want a stout and a lager on at the same time, well, cheapest option is to choose an intermediate or a get a T piece and another fridge... or get a dual reg and keep one fridge and do it the other (calculatory way - and yes I'm aware thats probably not a word ) with dedicated lines for various carbonation levels......

OK so that post got a little out of hand I guess...probably OT, I can't even remember the point of writing in the first place...hmm.. well, have fun reading anyway
