I was just wondering. The picture should be self-explanatory.

Blue = air @ 110psi
Red = air @ 120psi

Last post

There isn't a greater pressure in the main chamber, it's the same. The piston is held on by the vacum created by the unpressurized barrel.

ok so im going for around 300psi on this one. so do you think it will work to put 2 150 psi QEV's or will the QEV's not hold the load evenly

Last post

QEV's can actually handle 300psi anyway

At least this type can:

Thats no guarantee that the QEV types where you are will take that pressure though.
