Motor-operated valve (MOV)

Flanged wedge-gate valve with bolted bonnet and yoke carrying a multi-turn electric actuator: gearcase, motor housing, display window and local selector / control knobs, terminal box with cable glands, side handwheel with hand/auto lever, stem cover tube with sight slot. open raises the stem through the gate stroke.

Installation

Copies valves/motor-operated-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 { MotorOperatedValve } from './components/deck-twin/valves/motor-operated-valve'

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

Props

P&ID

Valve bow-tie with a stem to a circle containing M: the electric motor actuator. The tag bubble is usually MOV, XV or HV, and the valve fails in place (FL / FAI).

Circle with M = motor actuator; dome = diaphragm (control valve); rectangle = piston or spring-return (ESDV / BDV). A square with "M" is used by some legends for the same thing.

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

Add the Deck Twin "Motor-operated valve (MOV)" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add motor-operated-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 motor-operated-valve` for its props, ranges and ports. Render <MotorOperatedValve /> 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.
