Animation software naturally interpolates between two positions. For a film about a switching valve, that smooth movement can imply that every intermediate position is a meaningful operating state. Decide how the approved states will be presented before the artist adds easing or a continuous slider.
HAWE's directional-valve entry describes binary switching between positions. The film should use the terminology and behaviour confirmed for the featured component, rather than extending that description to every kind of valve. A proportional device would require a different explanation.
Make states the organising structure
Ask the supplier for the minimum set of states needed to explain the public story. Give each a clear name and a consistent visual arrangement. The audience should be able to compare what is connected or blocked without mentally rebuilding the entire diagram between shots.
A pair of still states with a deliberate transition may be more accurate than a physically elaborate moving cutaway. It also gives the reviewer an easier approval task: each state can be checked independently before the change is introduced.
Keep the project context nearby. A valve symbol alone may be meaningful to a specialist but opaque to a construction audience. Locate the component in the delivered package, then simplify only the relationship that the film needs.
Distinguish transition from an available setting
If motion between positions is shown, avoid a control handle or progress bar that appears to invite selection of an intermediate value. The graphic is explaining a change, not offering an operating interface.
Similarly, a pause halfway through the movement can become an unintended claim. Editors often add holds to match narration, but a hold on an intermediate drawing may look like a normal sustained state. Place explanatory pauses on approved states instead.
Check the sound design too. A long rising tone can make the change feel like continuous modulation. A restrained transition or no effect may better suit the intended distinction. The choice should follow the explanation rather than a generic motion-graphics style.
A hypothetical supplier review
Consider a package supplier whose first animation uses a sliding knob to move gradually from one labelled condition to another. The client recognises the endpoints but says that the knob suggests adjustability absent from the featured device.
The buyer requests two clearly labelled diagrams and a short state-change cue. The sequence becomes less visually elaborate but more faithful to the supplied account. This fictional example concerns the interpretation of a public graphic, not how to operate or test a valve.
For approval, ask what settings a viewer believes are available. If they describe a continuous range when the story is about discrete states, the interface metaphor has overridden the narration.
Record the approved state names and transition treatment in the graphics brief. Any actual timing, control logic or fail-state claim needs separate client evidence. The film-production team can clarify a relationship, but should not derive the component's behaviour from a convenient animation preset.
