1. A pneumatic actuator and control valve assembly characterized by:
a housing having a first control cavity for a control valve and a first actuator cavity for an actuator piston and rod assembly;
said first control cavity and first actuator cavity both being an elongated shape and being substantially parallel to each other;
said first control cavity having a supply port and first and second control valve outlet ports and at least one vent port with said control valve being movable through the first control cavity for controlling communication between the supply port, the first and second outlet ports and the at least one vent port;
said first actuator cavity having first and second ports at respective retracted and extended ends for shuttling the piston and rod assembly within the first actuator cavity between a retracted and an extended end position;
the housing having a first inlet and second inlet for passage of pressurized fluid to and from said housing, said housing having a supply passage from one of said first and second inlets to said first control cavity and a first and second flow path in selective communication to said supply passage for supplying the pressurized fluid from the supply passage to either the first or second ports of the first actuator cavity depending on an actuation state of the control valve for providing reversable movement of said piston and rod assembly between said retracted and extended end position;
said piston and rod assembly including a first piston and a first rod, said first piston is slidably movable within the first actuator cavity to move the first rod between the retracted and the extended end position with respect to the housing based on the actuation state of the control valve providing the pressurized fluid from the supply passage and to one of the first and second flow paths:
said housing having a plurality of flat sides with each side forming an edge with an adjacent side with the edges extending parallel to a longitudinal axis of said housing;
said first actuator cavity extending axially along to be parallel with said longitudinal axis and between said flat sides; and
said first control cavity being interposed between said first actuator cavity and one of said edges.
