A rotary drive for actuating a valve element of a valve fitting, having a housing, which has a drive device and a pivot-mounted driven shaft which can be driven by the drive device and which can be coupled to the valve element, and a position detection device for detecting a position of the driven shaft, wherein the position detection device has a magnet module attached to the driven shaft in a torque-proof manner and a sensor module which is fitted onto or into the housing and is designed to detect a magnetic field measurement value according to the magnetic field generated by the magnet module. The the magnet module and/or the sensor module is attached such that it can be removed from the rotary drive, and the rotary drive includes a control device, which is adapted to determine if the magnet module or the sensor module is removed from the rotary drive.

Rotary drive having a position detection device and calibration method

A fluid-actuated rotary actuator includes a housing having a tubular body extending in an axial direction, in which is provided a drive piston assembly for driving a rotatably mounted output shaft, which extends perpendicular to the axial direction through the tubular body and the axial end of which is routed out of the tubular body at an upper wall section of the tubular body, further including a magnet assembly associated with the axial end of the output shaft and receiving a rotary movement of the output shaft, and further including a position feedback device configured to detect the magnetic field generated by the magnet assembly and to provide, in accordance with the detected magnetic field, a position signal corresponding to a position of the output shaft, wherein the position feedback device is located in a receptacle chamber formed in the upper wall section of the tubular body.

Rotary actuator with position feedback device and process valve module

A slide drive device has a principal housing, in which at least one actuating element able to be driven linearly is arranged. Externally on the principal housing there is a slide kinetically coupled with the actuating element. Two stroke limiting means render possible a variable preset of the two end positions of the slide and each comprise an adjustable arranged on the one part and a counter-abutment arranged opposite to same on the other part. The one adjustable abutment is arranged on the slide and the other adjustable abutment is located on the principal housing. Both abutments are provided in end regions facing in the same axial direction, on the slide and, respectively, on the principal housing.
