Interpretation 1 — Nancy Wagaman
Regulation of a flow (such as of emotions or a process).
Control of flow, including stopping, starting, or regulating how fast something is allowed to proceed.
Consider also the context, role, and condition of the valve (for example, a steam exhaust valve might represent control over one’s anger, while a broken valve might represent someone who’s ineffectively managing a process).
