Product Description

Fisher 3572 4-20 mA Electro-Pneumatic Valve Positioner

The Fisher 3572 4-20 mA Electro-Pneumatic Valve Positioner is a precision control device designed to convert electrical input signals into proportional pneumatic output pressures for accurate valve actuation. Engineered by Emerson Automation Solutions, this positioner serves as a critical component in industrial process control systems, ensuring precise regulation of fluid flow, pressure, temperature, and other process variables. By bridging the gap between electronic control systems and pneumatic actuators, the Fisher 3572 delivers reliable performance in demanding environments such as oil and gas, chemical processing, power generation, and water treatment facilities.

Key Features and Functionality
The Fisher 3572 operates on a standard 4-20 mA DC input signal, which is commonly used in analog control systems. This signal is translated into a corresponding pneumatic output pressure to position the valve actuator with high accuracy. The positioner's electro-pneumatic transducer design ensures seamless integration with distributed control systems (DCS), programmable logic controllers (PLCs), or other automation platforms. It supports a wide range of supply air pressures (typically 14–150 psig or 100 kPa–1034 kPa), enabling adaptability to diverse plant requirements. The output pressure range is configurable, with common options including 3–15 psig (20–100 kPa) for standard applications or 6–30 psig (40–200 kPa) for high-force actuation needs.

The device incorporates a mechanical feedback mechanism that continuously monitors the valve's position and adjusts the output pressure to maintain the desired setpoint. This closed-loop control system minimizes errors caused by hysteresis, friction, or process disturbances, achieving typical accuracy of ±0.5% of span and repeatability within ±0.1% of span. For enhanced flexibility, the Fisher 3572 allows manual adjustment of zero and span settings via internal potentiometers, while optional HART® communication enables digital configuration and diagnostics through compatible field communicators.

Robust Design for Industrial Reliability
The Fisher 3572 is built to withstand harsh operating conditions. Its rugged aluminum alloy housing and stainless steel internal components provide durability in environments with extreme temperatures, humidity, vibration, and corrosive agents. The positioner meets NEMA 4X/IP66 environmental protection standards, ensuring reliable performance in outdoor or washdown areas. It operates effectively within a temperature range of -40°F to 180°F (-40°C to 82°C), making it suitable for both arctic and high-heat applications.

The positioner is available in configurations compatible with rotary and linear actuators, offering versatility across valve types such as globe, ball, butterfly, and plug valves. Its modular design simplifies installation and maintenance, reducing downtime during routine calibration or component replacement. Additionally, the device supports fail-safe operation through external relays or integral solenoid valves, ensuring process safety during power or signal loss.

Applications and Benefits
The Fisher 3572 is widely used in industries requiring precise valve positioning for critical processes. In oil refineries, it controls feedstock flow rates and pressure levels in distillation columns. In chemical plants, it regulates corrosive or viscous fluids with consistent accuracy. Power generation facilities employ the positioner to manage steam and fuel flow in turbines, while water treatment plants use it to optimize filtration and dosing systems.

Key benefits of the Fisher 3572 include:

Precision Control: Maintains tight tolerances for improved process efficiency and product quality.
Adaptability: Configurable input/output ranges and mounting options suit diverse actuator designs.
Low Maintenance: Durable construction and self-diagnostic capabilities reduce unplanned downtime.
Safety Compliance: Meets global standards such as CE, FM, and CSA for hazardous location certifications.

Technical Considerations
When deploying the Fisher 3572, proper air supply filtration and regulation are essential to prevent contamination and ensure consistent performance. Users should verify compatibility with the actuator's stroke length and torque requirements and calibrate the positioner according to manufacturer guidelines.
