Frequently asked questions
How does the cross-section identification quiz work?
A part on the ball-valve cutaway is highlighted with a pulsing glow and a question-mark pointer. Four names appear below; pick the one that matches the highlighted part. There are six rounds, one per part.
Which parts can the quiz ask about?
The ball, sealing seat, stem, handle, inlet port and outlet port — the main identifiable parts of a ball valve.
What happens if I answer wrongly?
Your choice is marked red and the correct name is highlighted in green, then the quiz moves on. You can restart any time to reshuffle the order.
Is this the same as the ball-valve explainer?
It uses the same cutaway style so you can practise the part names, but it is a quiz rather than a guided explanation. The related explainer walks through what each part does.
