For people who don't understand this: A pneumatic cylinder will normally start moving as soon as air starts to flow into it, If you lock a pneumatic cylinder in a slightly extended position and allow it to reach working psi, it will throw with a lot more force than just turning on air to it and having it extend slowly as air flows into it.

Actually the piston is receiving 60psi the instant the solenoid switches. The reason it shoots slower in normal function is because the air on the other side of the cylinder has to be pushed out by the new air coming in. It takes time to do this and force. If you stall the piston's extension in the manner you're talking about then this allows for the air on the other side of the cylinder to be released. Pressure does build up on the other side, but all the air technically doesn't go into the piston. After the shaft is released does the remaining air enter the cylinder.
