PNEUMATIC GUN WITH VALVE QEV

Made a gun of 40 mm caliber, used a piston valve. The gun works well at pressures up to 20 atm, no longer possible, because the rubber on the piston is torn.

here is an approximate diagram of the valve. Used a coarse water filter.

Re: PNEUMATIC GUN WITH VALVE QEV

A few days ago, I managed to make and test a piston valve with a caliber of 40 mm. I managed to make an exit into the barrel with a diameter of 14 mm. I pumped 50 atm into a cannon with a homemade pump.

QEV CO2 valve

Hello everyone. I made a new valve, it will work on CO2. How it looks inside can be seen in the diagram. The turner made the blue part for me on the machine, I soldered it inside the tee.
