Electro-Pneumatic Positioner
(4-20mA)

An electro-pneumatic positioner (4-20mA) is a device that precisely controls the position of a pneumatic actuator based on an electrical control signal, typically within the 4-20mA range. It converts the electrical input into a corresponding pneumatic output, ensuring accurate valve positioning in response to process control signals. This type of positioner is widely used in industries such as oil and gas, chemical processing, and power generation, where precise flow, pressure, or temperature regulation is critical. Electro-pneumatic positioners enhance system accuracy, improve response times, and integrate easily with automated control systems for optimal performance.
