Plastic valves and flowmeters I Positioners 101 Overview of GEMÜ positioners GEMÜ pneumatic actuators can usually be paired with our electro-pneumatic positioners and process controllers. In addition to the process parameters and the control system for which a positioner must be suitable, other technical functions and properties also play an important part in the selection of the right positioner. To make your choice easier, we have placed the four GEMÜ positioners in a comparison based on important features.
