Mechanical design
The electric actuators require no maintenance. They have a reversible synchronous
motor and reduction gears with self-lubricating sinter bearings. The housing base and
the console are die-cast aluminium, and the cover is plastic.
motor and reduction gears with self-lubricating sinter bearings. The housing base and
the console are die-cast aluminium, and the cover is plastic.
"AUTO" and "MANUAL" modes can be selected with a rotary switch on the housing
base. When the switch is set to "MANUAL", the actuator and valve can be operated
with a manual lever. For manual operation, the angle of rotation is mechanically limited
by an end-stop.
base. When the switch is set to "MANUAL", the actuator and valve can be operated
with a manual lever. For manual operation, the angle of rotation is mechanically limited
by an end-stop.
The actuators supplied have a 90° angle of rotation suitable for the Siemens valves.
During automatic operation, rotation is limited by two built-in end-switches. For non-
Siemens valves, the angle of rotation in the range 70° to 180° can be selected by
repositioning the switching cams.

The direction of operation of the actuator can be reversed (refer to "Commissioning").
