Overview

The Spirax Sarco EP5 Electropneumatic Positioner is engineered to provide precise modulation of pneumatic actuators in response to electrical control signals. It converts a standard 4–20 mA input into a proportional pneumatic output, enabling accurate valve positioning for flow, pressure, and temperature regulation. Moreover, the EP5 is designed for durability and reliability, supporting split-range operation, easy installation, and simplified maintenance. In addition, its compact design and robust construction make it suitable for both general industrial use and demanding environments such as chemical plants, refineries, and power generation facilities.
