5.1. Designated application area
The electromotive rotary actuator Type 3005 (designated below as rotary actuator) was developed to control ball
valves or flap valves with a quarter turn. Optionally the actuator is also available at a rotation angle of 180° and 270°.
5.2. general Description
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 "5.4. Options".
The rotary actuator is a compact and powerful actuator system which ensures a long service life. The rotary actuator
has been designed for direct or alternating current at varying output and for torques from 25 to 1000 Nm (actuator
with analogue signal 25 - 300 Nm).
The utilized materials guarantee maintenance-free operation and ensure a low thermal load. All standard version rotary
actuators 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 actuator. It can be combined with the
following components:
• Stainless steel ball valve with two-part body (Type 2651),
• Stainless steel ball valve with three-part body (Type 2654),
• Plastic ball valve (Type 2657),
• Metal flap valve (Type 2671),
• Plastic flap valve (Type 2674).
The actuator direction cannot be reversed in the same operating process. The rotary actuator does not reverse
automatically.
Mechanical operation is also possible via the handwheel on the rotary actuator. In electrical mode the handwheel
is not rotated with the actuator.
