Position regulator for drives of control valves has magnetic drive elements to transmit rotational position of feedback shaft to externally installed rotational position indicating element installed in Exd housing with window

摘要

The position regulator for the positioning of actuating drives of control valves has a feedback shaft (1) guided on the inner wall of the regulator housing (10), and via magnetic drive elements (2,3) the rotational position of the feedback shaft is transmitted to an externally installed rotational position indicating element installed in a dust-protected housing constructed as a double-walled cap (12) provided with a window surface (13).
