To regulate the flow of fluid. Thus, since the plumbing facilities are buried in a certain depth into the ground, the dilution valve installed there is also separated from the ground by a certain distance, which makes it difficult to directly adjust the control cap.

In order to solve this problem, the control cap was extended upward from the body of the dividing valve so that it could be positioned as close to the ground as possible, but this also caused the ground surface to be raised due to the overlaying of the road. It was difficult to solve.
