Re: Pneumatic Ball Puncher

We have tested with four 3/4" X 10" stroke cylinders with a festo solenoid valve per cylinder and an accumulator feeding each valve at 60psi and have been able to get about 7 feet straight up from the ball resting on top of the cylinders that are spaced evenly around a 4" diameter tube. We were getting 4' with three. We plan to use 6 and hold with vacuum next test. Will let you know how it works... Not a punch -- more of a put (like shot put).
