Product Overview
The Bürkert 8692 (part number 00227316) is a high-precision electro-pneumatic positioner engineered for the closed-loop control of pneumatically actuated process valves. Operating on the force-balance feedback principle, the unit compares the actual valve stem position against a 4–20 mA or 0–10 V setpoint signal and modulates the pilot air output to the actuator until the deviation is eliminated. As a core component of Bürkert’s modular automation platform, the 8692 integrates seamlessly with linear and quarter-turn actuators, delivering fast, stable, and repeatable positioning in demanding process environments. Its robust die-cast aluminum housing and non-contacting position sensing make it a reliable choice for continuous industrial duty in chemical, water treatment, and general process automation systems.
