Valve positioners are control devices that ensure a valve reaches the desired position accurately by comparing the control signal to the valve’s actual position and adjusting as needed. They improve valve response time, accuracy, and stability, which is crucial in process control applications.

Positioners can be pneumatic, electro-pneumatic, or digital and often integrate with smart systems for diagnostics and predictive maintenance. By minimizing hysteresis and enhancing precision, they contribute to energy savings and extended valve life. They’re widely used in chemical plants, refineries, and pharmaceutical industries.
