the present invention relates to an improved sequencing disk means for fluid handling in a sequencing valve having a plurality of outlets . sequencing valves deliver fluid from the inlet sequentially out through one or more fluid outlets in a predetermined sequencing cycle . the sequencing disk means reciprocates and rotates to sequentially deliver fluid under both high or low fluid flow rates from an inlet to a plurality of discharge outlets . the improved sequencing disk means includes a main sealing means , a stem connected to the main sealing means , and a generally cup - shaped check valve means with a relatively small opening in the bottom of the cup - shaped portion . the stem and check valve means includes connecting means that cooperate to fix the stem relative to the main sealing means or sequencing disk .
