Mounting arrangements
Mounting types A, B*, C and D* are possible for mounting the Type AT Actuator on the valve.
* For control valves with manual gearboxes, mounting positions B and D must be checked due to the risk of collision with the pipeline.
Mounting type A is selected as the standard mounting position if no other information is available.
Exemplary illustration of mounting position A. For other mounting positions, see data sheet.

FTO = Medium opens ( flow from the front, on the seat side) • FTC = Medium closes ( flow from the rear)
Accessories
The control valves can be equipped with various accessories: Positioner, solenoid valve, supply pressure regulator, limit switch, volume booster/booster and other attachments.
Mounting of accessories (attachments) to pneumatic rotary actuators is performed according to two standardized mounting methods:
