3/4" QEV piloting

[woodscout]

is the 3 way push button valve(small) enouhg to pilot an 3/4" QEV? its going to be used on a marble rifle. also how much pressure do i need to shoot the marbles pretty high velocity because my chamber size is going to be 20mm x 180mm?

What valve 'exactly' (part number, link, picture) are you talking about. What is your chamber made of? You have to be more discriptive, we are not mind readers...

depends what your definition of high velocity is, 200 fps 1000fps, or some other number?

I think it would be too small. Even if it could pilot a QEV, it wouldn't do it very well. That's assuming the 3/2 is 1/8" threaded.

yeah most 1/8" valve will have too little flow... possibly clippard's MJVO-3 is good enough but I can't test it


alternatively you can use an aux. QEV to pilot the main QEV

I tested this with a 1/8" QEV that you can see in the pic below and it works great
