Description

Spirax Sarco SP7 Valve Positioner

Product Overview

The Spirax Sarco SP7 is a digital electro-pneumatic positioner designed for accurate control of pneumatic actuators on control valves. It accepts a 4–20 mA input signal and uses HART communication for configuration and diagnostics. The positioner is compact, easy to calibrate, and well-suited for steam and process applications where reliable digital positioning is required.
