Hi
I have a friend traveling in the US for the next 2 weeks. He promised to carry some stuff home 2 me, because it's veeeery much cheaper in USA than in Denmark.
So, guys, where do i find a supplier of 1/2" motorized ball valves in a fail safe version meaning that if you apply power it opens, and if you turn of the power it's closes. It's called "spring return", "fail safe" or CR04. 12 V, 24 V or 220V. I need min. 6 and go for 10.
That type can directly replace a solonoid valve.
I've build 5 clycol chilled 200 liters SS fermenters. I attached a coil of copper pipe to the outsite walls of the fermentor with aluminum tape, and the insulate them with 50 mm (2") mineral wool, with aluminum front. They are all chilled by a beer line chiller and works perfedt.
The only thing is that the solonoid valves used to open and close for the coolant, couldn't stand beeing applied power for many hours, when i drop from fermentation temperatur to carbonation / tapping temp (1 degree celcious).
Hope you can help.
If you are interested in pictures, i for shure can opload some.
Thanks
