ABSTRACT:
This invention relates to sequencing valves for distributing fluid from an inlet selectively to one of a plurality of outlets in response to variation in the pressure of the source fluid. The improvement provides a visual indication of which particular outlet is connected to the inlet at any particular time. The invention may be practiced as a retrofit kit for installation on conventional valves or a new valve may be provided with the position indicating features of the invention.
