Abstract
An air pressure control system for use where a plurality of various sequential and repetitive air pressures are selectively required. A pilot air operated pressure regulator valve having a pilot air operator and a working air flow control valve are connected in series in a pressurized working air conduit between a source of pressurized air and an air cylinder. A pilot air pressure selector circuit means, for selectively and sequentially providing a plurality of pre-set pilot air pressures to the pilot air operator of the pilot air operated pressure regulator valve, includes a plurality of pressurized pilot air conduit means which are connected in parallel with each other, and with one end of each pressurized pilot air conduit means being operatively connected to the source of pressurized air and the other end thereof being operatively connected to the pilot air operator of the pilot air operated pressure regulator valve.
