Abstract: A pneumatically energized, pre-packaged, unit for selectively controlling the pressure, cycle and time duration of an air actuated work device includes a protective housing having an air pressure regulator, an air inlet orifice and a visably exposed pressure gauge adapted to communicate with an external source of pressurized air. The housing also contains a pair of three-way time delay valves and auxillary volume chambers, with integral time delay adjustment knobs protruding above the top surface of the housing. Also contained within the housing is a four-way valve means, either of the single or double piloted type, which is pneumatically piped, either in a parallel or series circuit array, to the three-way time delay valves and the air pressure regulator.
