Kegland - just to confirm two things about the Blowtie spunging kit -
1) if there is a pressure drop befor the valve & there is no gas hooked up air from the outside can’t flow back though the valve?
2) if the gauge a few the Tee piece are placed after the valve it could be used as an accurate secondary regulator?
Also I noticed that it is possible to push the black tubes further than
required in the Tee piece - no dramas just something to watch out for!
Great bit of kit though!
I think I know the answers but thx in advance
Cheers
Hello Kenf,
1. I believe this should not be possible for the air to flow back. I have not tested this myself so i will have to make sure but it should not be possible.
2. The blowtie only regulates air coming out of the pressure vessel. (IE it ensures that excess pressure above a certain set point is released). Normally when customers refer to a regulator they are wanting to regulate the gas flow from a high pressure tank and want to set the output pressure (irrespective of the high pressure source pressure). So if you want an inline regulator that will do that then you should purchase this part:

this is a really useful part and this is a really cheap way to setup your system with multiple pressures without the cost of large regulators.
This device can also be used on mains water pressure to reduce mains water pressure to a lower pressure. I actually use this regulator to connect a ball lock post next to my sink so I can have a a water supply to wash our beer lines and stuff next to my sink.
If you can give me more advice on what you want to use the secondary regulator for and what you are trying to setup I can probably give you my opinion on the best selection of parts for the job.
