Ball valve
Flanged RF ball valve. Floating two-piece body with a wrench lever for small sizes, trunnion-mounted three-piece side-entry body with sealant fittings, trunnion cover, lifting lugs and a worm gear for larger sizes. Full or reduced bore; the ported ball is visible down the bore and turns with open.
Installation
Copies valves/ball-valve.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.
Usage
import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { BallValve } from './components/deck-twin/valves/ball-valve'
export default function Scene() {
return (
<Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
<Stage>
<BallValve />
</Stage>
<OrbitControls makeDefault />
</Canvas>
)
}

P&ID
Bow-tie across the line with an open circle at the centre where the triangle points meet. Manual valves may show a stem with a T or a lever.
Open circle = ball; filled dot = globe; plain bow-tie = gate. The same body under a square actuator with an S or a fail-close note is an ESDV / SDV / XV (esd-valve). Some legends write FB / RB beside it for full or reduced bore.

For agents
Machine-readable entry with props, ranges, defaults and ports:
Or fetch /r/ball-valve.json, or copy a ready-made instruction:
Add the Deck Twin "Ball valve" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add ball-valve` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info ball-valve` for its props, ranges and ports. Render <BallValve /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
