Control valve (globe)

Flanged globe control valve with a multi-spring diaphragm actuator on a two-leg cast yoke. Includes a digital valve positioner with gauges, an air filter-regulator with gauge and bowl, stainless tubing to the diaphragm casing, a stem connector with travel pointer and scale. open lifts the stem through the rated travel. Face-to-face per ISA 75.08.01.

Installation

Copies valves/control-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 { ControlValve } from './components/deck-twin/valves/control-valve'

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

Props

P&ID

Bow-tie body with a stem up to a dome (half circle on a flat base): the spring-diaphragm actuator. A tag bubble such as LV, PV, FV, TV, PCV, LCV, FCV, TCV sits next to it, often with FC / FO / FL and a bypass globe valve drawn around it.

tag CVISA LVISA PVISA FVISA TVISA PCVISA LCVISA FCVISA TCVISA HCVISA PDVISA 5.1 / ISO 10628-2 (control valve with diaphragm actuator)

Dome = diaphragm actuator (control valve). A rectangle = piston actuator (usually on/off: ESDV / SDV / XV / BDV). A circle with M = MOV. A self-acting regulator (PCV with no signal line, impulse line to the pipe) uses the same body with a sensing line instead of a positioner signal.

For agents

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

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

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