Intended Use
The device is designed for the controlled flow of liquid and•
gaseous media.
The admissible data, the operating conditions and conditions of•
use specified in the contract documents, operating instructions and
on the rating plate are to be observed during use. The designated
application cases are specified in the chapter entitled "Product
description".
The device may be used only in conjunction with third-party devices•
and components recommended and authorised by Bürkert.
Correct transportation, correct storage and installation and careful•
use and maintenance are essential for reliable and problem-free
operation.
Use the device only as intended.•
If exporting the system/device, observe any existing restrictions.
Supply the media connections only with those media which are•
specified as flow media in the chapter entitled "Technical Data".
Do not put any loads on the valve (e.g. by placing objects on it or•
standing on it).
Do not make any external modifications to the valves.• Do not paint
the housing parts or screws.
The actuator housing must not be opened. If opened, there is a risk •
of injury from the tensioned spring inside.

Basic 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.
Before loosening the lines and valves, turn off the pressure and•
vent the lines.
Before reaching into the device, switch off the power supply and•
secure to prevent reactivation!
Observe applicable accident prevention and safety regulations•
for electrical equipment!
Warning!
The actuator contains a tensioned spring. If the actuator housing
is opened, there is a risk of injury from the spring jumping out!
The actuator housing must not be opened.•
Caution!
The surface of the device may become hot during long-term
operation.
Do not touch the device with bare hands.•
To prevent injury, ensure that:
T• he system cannot be activated unintentionally.
Installation and repair work may be carried out by authorised•
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.
The diaphragm valve Type 2103 was developed with due
consideration given to accepted safety rules and is state-of-
the-art. However, dangers can still arise.

There is also complete documentation on CD. The complete operating
instructions can be ordered by quoting the following identification
number: 00805642
The piston-controlled diaphragm valve Type 2103 is suitable for
liquid and gaseous media.
Using neutral gases or air (control media), it controls the flow of
dirty, aggressive, ultrapure or sterile media, even highly viscous
media can be used (flow media).
Any flow direction.•
Self-draining for appropriate installation. The ends of the utilised •
connections must be cylindrical.
Free of empty space•
Low-turbulence flow•
High flow values by the streamlined valve housing•
Maintenance-free under normal conditions.•
Activation unit •
Different versions of the activation units are available depending
on the requirement.
Stroke limit •
Limit of the maximum open position /flow rate by means of
adjusting screw.

The indicated medium temperatures apply only to media
which do not corrode or swell the diaphragm materials.
The behaviour of the medium with respect to the dia-
phragm may be changed by the medium temperature.
The function properties, in particular the service life of the
diaphragm, may deteriorate if the medium temperature
increases.
