Correct Use
The rotary actuator can be used indoors, e.g. to actuate fittings, especially ball valves or shut-off flaps.•
During use observe the permitted data, the operating conditions and conditions of use specified in the con-•
tract documents and operating instructions, as described in chapter 6.System Description.
The device may be used only in conjunction with third-party devices and components recommended and •
authorized by Bürkert (e.g. ATEX-approved components).
Correct transportation, correct storage and installation and careful use and maintenance are essential for reli-•
able and problem-free operation.
Use the device only as intended.•
If exporting the system/device, observe any existing restrictions.
Do not put any loads on the housing (e.g. by placing objects on it or standing on it).•
Do not make any external modifications to the device housings.• Do not paint the housing parts or screws.
It is forbidden to open the housing for specific device designs in the explosion-protected area. Follow the safety •
instructions on the rating plate.
Do not install the actuator with the cover facing down (head first).•
The electromotive rotary actuator Type 3004 was developed with due consideration given to the accepted
safety rules and is state-of-the-art. However, dangers can still arise.
Operate the device only when it is in perfect condition and in accordance with the operating instructions.
Failure to observe these instructions and unauthorized tampering with the device release us from any liability
and also invalidate the warranty covering the devices and accessories!

General Safety Instructions
These safety instructions do not make allowance for any:
Contingencies and events which may arise during the installation, operation and maintenance of the devices.•
Local safety regulations; the operator is responsible for observing these regulations, also with reference to the •
installation personnel.
There is a serious risk of injury when reaching into the device.
Before reaching into the device, always switch off the power supply and safeguard to prevent re-activation!•
Connect several electromotive rotary actuators always with phase separation via a switch.•
Protect the device with a mains-operated fuse.•
Observe applicable accident prevention and safety regulations for electrical equipment!•
For specific device designs there is a risk of explosion if the device is opened in the explosion-protected area.
Follow the safety instructions on the rating plate!•
If there is a sudden discharge from electrostatically charged devices or persons, there is a danger of explosion in
the EX area.
Take appropriate measures to prevent electrostatic charges in the EX area.•
Clean the device surface by wiping it gently with a damp cloth.•
that the system cannot be activated unintentionally.•
Installation and repair work may be carried out by authorized technicians only and with the appropriate tools.•
After an interruption in the power supply or pneumatic supply, ensure that the process is restarted in a •
defined or controlled manner.
The device may be operated only when in perfect condition and in consideration of the operating instructions.•
The general rules of technology apply to application planning and operation of the device• .

This document contains no promise of guarantee. Please refer to our general terms of sales and delivery. The war-
ranty is only valid if the electromotive rotary actuator Type 3004 is used as intended in accordance with the specified
application conditions.
The warranty extends only to defects in the electromotive rotary actuator Type 3004 and its components.
We accept no liability for any kind of consequential damage which could occur due to failure or malfunction of
the device.
ATEX actuators are delivered in reference to specific order. Because of this, it is not possible to return or replace
materials that have already been delivered.

System Description
The explosion-protected electromotive rotary actuator Type 3004 (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°.
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 6.4.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 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 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 actuator 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 actuator.
