    If an error exists, the electropneumatic system causes the actual position to be appropriately corrected. The type 1067 positioner can be fitted to various continuous valves (e.g. valves with piston, membrane or rotary drives and with single or double action). Two variant forms of the basic device are offered that differ in their fixing options and feedback/positional transducers.
