Product Overview
The BURKERT 8694 (Part No. 00227411) is a high-precision electro-pneumatic positioner engineered for the reliable control of pneumatically actuated process valves. As a core component within Burkert’s renowned automation and control portfolio, this positioner operates on a force-balanced electro-pneumatic principle, converting a standard electrical control signal into a precise pneumatic output pressure. This allows for accurate valve stem positioning, ensuring optimal flow control, tight shut-off, and enhanced process safety in demanding industrial environments. It is specifically designed to be a direct-fit, high-performance solution for automating quarter-turn and linear actuators, serving as a critical interface between the central control system (PLC/DCS) and the final control element.
