Abstract
A pneumatic control system is provided for positioning a piston within a cylinder and comprises a positioner for regulating the flow of compressed air into and out of first and second ends of the cylinder. First and second large boosters force compressed air into the respective first and second ends. First and second small boosters and first and second quick exhaust valves collectively exhaust compressed air out of the respective first and second ends. First and second small and large booster check valves interposed between the directional valve and the respective first and second small and large boosters are oriented such that the flow of compressed air through the signal lines and into the first and second small and large boosters may be blocked for increasing the sensitivity of the positioning of the piston.
