Spiraxsarco Pneumatic Control Valve and Masoneilan SVI2 Control Valve Positioner and Reliable 4700E Electro-pneumatic Controller and FOXBORO Positioner SRD991

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.

• 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.

Ideal for precise positioning of control valves in oil & gas, refining, chemical processing, power generation, and other industries where corrosion resistance, fast response, and customizable flow characteristics are required.
