Course overview
A valve positioner is a type of relay used between the valve's controller output and the valve diaphragm. The positioner increases or decreases the signal operating the valve actuator, helping the valve's final control element more accurately reach the desired position. The Valve Positioner training course describes the basic design and function of valve positioners used in industrial facilities. Valve Positioners is part of the Valve Selection and Maintenance training series.
