Convert airgun/Paintball gun to be fired by a computer (12v solenoid valve) Answered

Hi!

I have a project this summer where I need to convert a paintball marker and a co2 Airpistol to be fired by the use of a solenoid valve powered by 12v.

The project goal is high-speed photography, more or less photographing object being hit by a projectile.

What i need is a way to fire these guns precisely by the use of my computer and software, and since I already have plenty of 12 solenoid valves that work with this system I thought my easiest way is to adapt these valve to trigger the guns one way or another.

I just purchased a Valken V-TAC SW-1

which I plan to use as base (for parts) My reason for getting this particular one was that it was on sale for 50% and seems to be fairly popular as it's based on the Tippmann 98 design.

I attached an image of the valve I used with my controller and software (Cognisys Stop shot) now I can probably use any 12v solenoid valve (with the same spec ?) as the one I use now so it doesn't need to be these exact valves.

As long as they can be operated by turning on-off power with the same powersource i use to control my current solenoid valves.

From my understanding, most airguns use a pin valve, which is hit by a trigger mechanism that is then rearmed by the blowback.

What would be the best way to modify an airgun for my needs? Replace the pin valve with a suitable solenoid i can control instead? Or go for a design that uses maybe use a piston and 2-way valve to hit that pin?

The gun does not need to be mobile or ergonomic, it will be placed in a rig regardless, however keeping the barrel and keep the Picatinny is preferred to be able to mount marking aids etc. and mount the gun to a tripod.

Any tips or suggestions are highly appreciated!

Thank you!

I don't see why a solenoid valve would not work, other than cycling it to open and close might be a little slow. However, that doesn't sound like it would make a difference for high speed photography if you are only firing it once.
