Knife gate valve

One-piece lug-type knife gate valve: thin body drilled through for the flange studs, bevelled stainless gate plate that rises out through a packing gland into a two-post yoke, rising stem and handwheel. The bore is open right through; open lifts the gate. Face-to-face typical MSS SP-81. For slurry, produced sand and utility service.

Installation

Copies valves/knife-gate-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 { KnifeGateValve } from './components/deck-twin/valves/knife-gate-valve'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <KnifeGateValve />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

Props

P&ID

Gate-valve bow-tie with a thin slab (two close parallel bars) drawn through the centre, standing proud of the body, and a handwheel stem.

tag HVISO 10628-2 / ISO 14617-8 / PIP PIC001

Legends vary: some show a knife gate as a plain gate bow-tie with "KG" written beside it. A single bar through the centre is a butterfly. Typical in slurry, sand, drain and low-pressure water service.

For agents

Machine-readable entry with props, ranges, defaults and ports:

Or fetch /r/knife-gate-valve.json, or copy a ready-made instruction:

Add the Deck Twin "Knife gate valve" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add knife-gate-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 knife-gate-valve` for its props, ranges and ports. Render <KnifeGateValve /> 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.
