Description
Overview
The Type 2000 Pneumatic and Electro-Pneumatic Valve Positioner is designed to provide stable, accurate positioning of both rotary and linear control valves. Its force-balanced design is simple, reliable, and user-friendly for calibration, maintenance, and field upgrades.
The Type 2000 is available in pneumatic and electro-pneumatic configurations, including intrinsically safe, explosion-proof, and natural-gas-capable versions. A rugged NEMA 4X / IP66 housing helps protect the instrument in severe industrial environments, while the modular design allows multiple factory options and convenient field conversion. :contentReference[oaicite:0]{index=0}

- Select FM/CSA Intrinsically Safe models when intrinsic safety approvals are required
- Select ATEX Intrinsically Safe models for applicable ATEX installations
- Select FM/CSA Explosion-Proof models for hazardous areas requiring explosion-proof construction
- Select ATEX Flame-Proof models for applicable ATEX hazardous areas
- Select Natural Gas models when sweet natural gas or methane will be used as the supply medium
- Select 4-20 mA Feedback when remote position indication is required
- Select Mechanical Switches when discrete open/closed or position indication is needed
