ABSTRACT:
A programmable-sequencing valve assembly for controlling plural fluid-operated motors, which includes a series of valve housing modules, sealably joined to one another thereby forming an elongate valve housing which receives plural valve inserts. The valve housing modules collectively form manifolds which may be connected to a pressurized source of fluid and an exhaust line. The assembly is mechanically programmable and provides a visible, non-volatile program to control multiple motors. Individual valves are actuated by cam-operated rocker arms. A cam shaft includes removable adjustable cams, a program may be quickly changed by replacing or rearranging the shaft, its associated cams, or nodules on the cams.
