Product Description
Product Overview

The Masoneilan 4700E is a robust electro-pneumatic positioner that uses a precision multi-lobe cam feedback system to deliver accurate valve positioning, fast response, and customizable control characteristics. Designed for use with both rotary and reciprocating actuators, it converts a 4-20 mA input signal into proportional pneumatic output, making it a trusted choice for demanding industrial control valve applications.

Features
  • Multi-lobe cam provides field-selectable linear, split-range linear, or equal percentage characteristics.
  • Corrosion-resistant internal components for reliable performance in harsh environments.
  • Fully enclosed adjustments protected from weather and contaminants.
  • Force-balanced design ensures precise and stable positioning.
  • Zero adjustment via spring button and turnbuckle for easy calibration.
  • Compact and rugged construction suitable for outdoor and severe service.
  • Compatible with Masoneilan control valves for optimized system performance.
