i'm making an INLINE toilet paper pnuematic with 4" pvc as the barrel and chamber.

i was planning to use a 1" modded sprinkler valve but im concerned it won't dump the air fast enough for such a big chamber (4 foot) to make a truly powerful shot.

are there bigger valves i can modify? if so, what is the size and brand name?

what would you guys suggest?

[ProfessorAmadeus]

quick exaust valves would work

can i use a qev on an inline? ive seen em on over unders

where do i find a qev? home improvement, auto/farm store?

im having a hard time finding a sprinkler that doesn't have flow control, all i can find is rain bird CP-100's and they look difficult to modify

feel free to add new suggestions

The biggest QEV I know a steady supplier of is a 3/4" one. It's sold on mcmaster.

Other than that, you can get fairly big sprinkler valves and larger QEVs on E-bay.
