Piston (lift) check valve
Globe-pattern lift check valve: bulb body with seat-bridge bulge, oval bolted cover with a domed piston guide and centre plug, lifting eye on larger sizes, cast flow arrow, drain plug and nameplate. Used on small-bore and high-pressure lines where a swing check would chatter. Globe face-to-face from ASME B16.10.
Installation
Copies valves/check-valve-piston.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 { CheckValvePiston } from './components/deck-twin/valves/check-valve-piston'
export default function Scene() {
return (
<Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
<Stage>
<CheckValvePiston />
</Stage>
<OrbitControls makeDefault />
</Canvas>
)
}

P&ID
Check-valve bow-tie (downstream half filled, flow arrow) with the globe-pattern dot at the centre on some legends; on most P&IDs it is drawn exactly like any check valve.
Identify it from the valve code (lift / piston check, usually small-bore or high-pressure, NPS 2 and below) rather than the symbol. Swing and dual-plate checks use the same base symbol.

Machine-readable entry with props, ranges, defaults and ports:
Or fetch /r/check-valve-piston.json, or copy a ready-made instruction:
Add the Deck Twin "Piston (lift) check valve" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add check-valve-piston` (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 check-valve-piston` for its props, ranges and ports. Render <CheckValvePiston /> 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.
