ABSTRACT:
A basic controller concept is disclosed for a sequencing distributing valve having a series of multiple outlets and a control timer to direct a like series of timed output signals thereto which allows the sequencing distributing valve to be rapidly pressure cycled to a desired outlet with synchronization between the sequencing distributing valve and control timer being established by a first pressure sensor for sensing cycling pressure and a second pressure sensor for sensing a pressure from a selected outlet of the sequencing valve. Continuing synchronization during cycling is provided by the valve housing pressure sensor which can advance the control timer each time the housing pressure of the sequencing distributing valve indicates that the sequencing distributing valve has cycled.
