FIRST rules limit us to 120psi to the accumulator and 60psi at working circuits, so that is the setting on the relief valves when we recieve them. However, these components are designed to work at 250psi, so the relief settings can be easily changed. After a little research i have descovered that the weak link in the tubing is the connections, which are rated to work at about 150psi. Usually pnuematic products are rated at less than 1/3 of their limit.

The next question is: Is FIRST paranoid?

they limit all working circuits to 60psi so that if someone managed to "stall" a piston, by somehow providing over a 180lbs of back pressure (for the 2" piston), the pressure in the system could hypothetically double, raising it to 120psi. This is still way under the safe operating range, and the circumstances described would be nearly impossible to create. So why does FIRST restrict us so much?

Also, would increased psi increase the speed of the 3/4" piston?
