On this gun I use a 3/4qev as the main valve and the 1/2bv instead of a combo of 1/4qev/blowgun for the pilot... I was comparing what would pilot the main valve fastest, and IMHO the 1/2bv will actuate the main valve faster than a blowgun would actuate the 1/4qev which would then actuate the main valve... Thats why I was comparing 1/2"bv to a modded blowgun...
if they were using it as a mainvalve on a 3/4" barrel the BV would be better(but on a sub .5" barrel the qev would be better)...poland_spud wrote:if a 1/2" BV was superior to 1/4" QEV no one would bother to use them...
I think for a few minutes there we were talking about different applications...
And I never use tubing or hose between my trigger and pilot valve(too much wasted co2), thats why I'll use a mechanical link on my cannon that will be valved at the shoulder(for compactness), prolly a bullpup coax...
