I currently use swagelok valves and would like something rated for lower temps to minimize leaks. I use avco cryogenic valves for a lot of my system, but i’m wondering if anyone knows of a cheaper alternative.
Finally moving from a mastercool tank to a stainless tank (thanks to killa) and I want to make sure I put some quality valves on it that wont be likely to leak when -70 or below butane is flowing through them.
Yes, depending on the series but they perform well at the pressures we use. You may have to tighten the packing nut at lower temps. You can grab the Superloks with PEEK seals for lower temps. @CorleeValve should be able to help you out.
