Control drive, especially modular pneumatic drive, e.g. for regulating valve, has position regulator in at least 2 parts with drive module unit in drive housing, separate regulator module unit

摘要

The control drive has a drive housing (1), a drive rod (2) acted upon by a control motor, a tapping (3) for detecting the control displacement and a position regulator (5,6) with functional unit modules required for operating the position regulator as a pneumatic, electro-pneumatic or digital position regulator. The position regulator is in at least two parts with a drive module unit (5) in the drive housing and a separate regulator module unit (6) with an electronic regulator.
