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.
In an automatic sprinkling valve having a housing, an inlet and a plurality of outlets in said housing, a movable valve member within said housing constructed to connect the inlet sequentially with each of the outlets, a mechanism responsive to sequential increases and decreases in pressure at the inlet for moving said valve member in a combined rotary motion about a central axis and reciprocating motion to connect the inlet sequentially with each of said outlets, the improvement comprising: (a) an enclosure attached to the exterior of said housing, said...
