MK15/20/25/19 How about that?

Great history, @Angelo Farina and @axxel57!
Would love to see some diagrams of the old Mk19 to compare with the promo materials here, to figure out how the EVO improved performance.

And what a pleasure reading @DA Aquamaster again! I wish he were more active now.

Thank you to you both!

I guess there's nothing new under the sun. But it was fun reading about all the MK25 freezing comments, knowing what we now know about their new coated spring, the composite piston and the anti-ice components.

Still, maybe the Mk19 was just ahead of its time. With improved engineering, and such great flow, perhaps it will catch on. Sealed regulators rule!

Here are two cross sections for the Mk17EVO and the Mk19EVO for comparison.
Does anyone have any promotional material for the old Mk17 or Mk19 that we can use to compare?

Ask and ye shall receive.

beat me to it Robert. My NAS was needing a firmware update...

Yeah, The Naval Air Station where I used to work was in the sticks too. :-D

Keep going, @rsingler!!

Anyone have a schematic of the MK19?

I do, I'm pretty sure. I'll check.

As an aside, I got 2xG260 for a Japanese customer, 1 cracking at 1.8" the other 1.6", one wouldn't free flow as lever was too low...sigh.

It's the older version, but hopefully of some use to someone:

This is the only way I could upload it, sorry.

 

[buddhasummer]

No idea what this means:

A screen shot is all I can do.

@Andrew Dawson just emailed you the file.

Take care
