Product Overview

The Schubert & Salzer 8049-4 / 4099713 (8049/4P6-1S000-11-00) is a high-precision electro-pneumatic positioner engineered for the accurate control and positioning of pneumatic control valves in demanding process environments. Operating on a force-balance feedback principle, the unit converts a standardized electrical input signal into a proportional pneumatic output pressure, driving the actuator stem to the exact position commanded by the control loop. As a core component within process and pneumatic valve assemblies, it delivers reliable, repeatable valve positioning for throttling and on/off control duties across chemical, petrochemical, and industrial automation systems.
