The Fisherr 3572 Pneumatic Valve Positioner is a high-performance device designed to enhance the accuracy, reliability, and responsiveness of control valves in industrial processes. As a critical component in pneumatic control systems, it ensures precise positioning of the valve stem in response to pneumatic control signals, thereby optimizing process efficiency, safety, and product quality. This positioner combines robust mechanical design with advanced pneumatic technology to deliver exceptional performance in diverse applications.
The 3572 accepts a standard pneumatic input signal ranging from 0.2 to 1.0 bar (3 to 15 psi) or 0.4 to 2.0 bar (6 to 30 psi), depending on the specific model and configuration. This input signal is proportional to the desired valve position and is typically provided by a controller or other control device.The positioner generates a pneumatic output signal that is used to actuate the valve actuator. The output signal range is adjustable and can be matched to the requirements of the specific valve actuator. Common output signal ranges include 0.2 to 1.0 bar (3 to 15 psi) and 0.4 to 2.0 bar (6 to 30 psi).The 3572 requires a supply pressure that is typically 0.3 to 0.5 bar (4.5 to 7.5 psi) higher than the maximum output signal pressure. This ensures that the positioner has sufficient power to actuate the valve actuator quickly and accurately.The positioner is designed to operate in a wide temperature range, typically from -40°C to +85°C (-40°F to +185°F). This makes it suitable for use in harsh industrial environments, including those with extreme temperature variations.
Features
The 3572 features low air consumption, which helps to reduce operating costs and improve energy efficiency. The exact air consumption depends on the specific model and operating conditions but is typically in the range of 0.5 to 1.5 Nm³/h.The positioner offers a fast response time, ensuring rapid and accurate valve positioning. The response time is typically less than 100 milliseconds, making it suitable for applications requiring tight control of process variables.
The 3572 is available with various enclosure ratings to suit different environmental conditions. Common enclosure ratings include IP65, which provides protection against dust ingress and low-pressure water jets. For hazardous environments, it is available with explosion-proof certifications such as ATEX and IECEx.
The 3572 operates purely on pneumatic principles, making it suitable for use in environments where electrical power is not available or where electrical devices pose a safety risk. Pneumatic operation also provides inherent fail-safe capabilities, ensuring that the valve moves to a predefined safe position in the event of a loss of air supply.

Product Overview
The positioner features a high gain amplifier that provides a strong output signal relative to the input signal. This allows the positioner to overcome friction and other resistances in the valve and actuator, ensuring accurate and reliable valve positioning.The zero and span of the 3572 can be easily adjusted to match the specific requirements of the valve and process. This allows for precise calibration and ensures that the valve operates over its full range of travel.The 3572 can be configured for either direct or reverse acting operation. In direct acting mode, an increase in the input signal results in an increase in the output signal, causing the valve to open. In reverse acting mode, an increase in the input signal results in a decrease in the output signal, causing the valve to close. This flexibility allows the positioner to be used with a wide variety of valve types and actuators.
The positioner includes a quick exhaust feature that allows for rapid venting of the actuator air when the valve needs to close quickly. This is particularly important in applications where fast valve response is critical, such as in emergency shutdown systems.The 3572 is built with a rugged construction that can withstand harsh industrial environments. The housing is made of durable materials that resist corrosion, vibration, and mechanical shock, ensuring long-term reliability and performance.The Fisherr 3572 Pneumatic Valve Positioner operates on the principle of force balance. The input signal, which is proportional to the desired valve position, is applied to a bellows or diaphragm assembly. This creates a force that is balanced against a feedback force generated by the valve stem position.
