The invention relates to a positioner device for positioning the piston and piston rod of a double-acting, pneumatic operating cylinder at a preselected position for setting the position of a device connected thereto, such as the lever of a throttle valve, for example, with the positioner device having a locking device connected to the piston rod which can be controlled by a control valve for securing and maintaining the piston and rod in the selected position, without variance, until deliberately changed.
