Product Overview
The BURKERT 8693 (Part No. 00227360) is a precision electro-pneumatic process controller engineered by Bürkert for closed-loop regulation of pneumatic control valves and actuated process lines. Combining an integrated positioner, process controller, and PID control algorithm within a single compact housing, the Type 8693 continuously compares a 4–20 mA or 0–10 V setpoint signal against the actual valve stem position and modulates the pilot air output to eliminate deviation. This device serves as the intelligent control interface between a central PLC/DCS system and pneumatically actuated control valves, delivering fast response, high positioning accuracy, and reliable operation in demanding industrial process environments.
