There was a finned, inline expansion chamber made. I think I saw one last year (used). That adds volume though.
Looking at a Nelson, you could fin the valve body on the outside, and I'm thinking that an aluminum insert shaped like a "venturi" bolt front, or inline honeycomb pushed inside the body with a compatible heat sink grease (if there is such a thing) would help boost surface contact internally.
I wonder if a loose sintered bronze sleeve would breathe well enough for that duty. If it didn't, the change in the flow curve might not be a bad thing.
Yeah on the flip side I can count the number of days above 90 on one hand each year.
For inserts I have something coming That might help out some. I'll let the cat out of the bag after I get a chance to test it.
I'm thinking the fins would likely be most helpful on a BBA or Dropout valves since 100% of the CO2 will have to to through the finned section of the valve.
