Pneumatic Circuit
The way the Sprint LC is programmed determines which valves are
activated and in what order valves open and close. All, or merely a few,
components in this circuit might be used in a testing application.

Sprint LC has all valves and pneumatic components in one package to
perform pressure decay, occlusion, flow, and burst testing, if so equipped.
