ABSTRACT:
Changeover valves are provided for a dual filter system which are characterized by auxiliary bypass and vent valving to facilitate changing over from one filter to the other. The bypass valving allows a process fluid to fill the second filter while the first is still in service and without a substantial reduction in process fluid flow or pressure to downstream equipment; and the vent valving permits elimination of air or gases from the second filter before it is put into service.
