Designated application area
6.1.
The electromotive rotary
actuator Type 3005 (designated below as rotary drive) was developed to control ball valves
or flap valves with a quarter turn. Optionally the drive is also available at a rotation angle of 180° and 270°.
general Description
6.2.
On account of its modular design the basic device can be expanded with many options.
Options for expanding the basic device can be found in chapter
.
The rotary actuator
is a compact and powerful actuator system which ensures a long service life. The rotary actuator
is designed for direct or alternating current at varying power and for torques from 25 to 1 000 Nm (drive with ana-
logue signal 25 - 300 Nm).
The utilised materials guarantee maintenance-free operation and ensure a low thermal load. All standard version rotary
actuator feature manual emergency actuation and two additional limit switches and are tested by the manufacturer.
The limit switches have been set to 0 - 90° swivel operation.
The electromotive rotary actuator
is available as an On/Off or variable speed drive. It can be combined with the
following components:
Stainless steel ball valve with two-part housing (Type 2651)
•
Stainless steel ball valve with three-part housing (Type 2654)
•
Plastic ball valve (Type 2657)
•
Metal flap valve (Type 2671)
•
Plastic flap valve (Type 2674)
•
The drive direction cannot be reversed in the same operating process. The rotary actuator does not reverse
automatically
.
Mechanical operation, without switching over the motor, is also possible via the handwheel on the rotary actuator.
In electrical mode the handwheel is not rotated with the drive.
