Abstract: A time cycle actuator having first and second chambers pivotally secured on opposite sides of a support such that a fluid may flow through a flow control valve from one chamber to the other. The chambers are arranged to move a valve element in a valve block to allow flow from an inlet supply line to one of two exhaust lines. The fluid passes from the first chamber to the second chamber thus causing the second chamber to move, actuating the valve to allow flow through the first exhaust line. The first exhaust line is connected to one side of an actuated valve, and a reset means moves the second chamber to higher position to reverse the flow of fluid back to the first chamber. When a predetermined amount of fluid has flowed back to the first chamber the valve is moved to the second position allowing pressure to be applied to the second exhaust line. The second exhaust line is connected to resetting means and moves the actuated valve to the second position.
