Authorized Use
2. AUTHORIZED USE
Non-authorized use of the devices may be dangerous to people,
nearby equipment and the environment.
• The diaphragm valves of Types 2030, 2031, 2031 K, 2032, 2033
and 2037 are designed for the control of contaminated, ultra-pure
or sterile media, as well as for abrasive or aggressive media (also
with higher viscosity).
• The devices may be used only for media which do not attack the
body and seal materials (see type label). Information on the resis-
tance of materials to the media is available from your Bürkert sales
office or on the Internet at www.burkert.com Documentation
Brochures & Catalogues Chemical Resistance Chart.
• During use observe the authorized data, the operating conditions
and conditions of use specified in the contract documents and
operating instructions. These are described in the chapters “5.
System Description” and “6. Technical Data”.
• The device may be used only in conjunction with third-party devices
and components recommended and authorized by Bürkert.
• Correct transportation, correct storage and installation and care-
ful use and maintenance are essential for reliable and faultless
operation.
• Use the device only as intended.
2.1. Restrictions
If exporting the system/device, observe any existing restrictions.
2.1.1. Explosion Protection Approval
The explosion protection approval is only valid if you use the modules
and components authorized by Bürkert, as described in these oper-
ating instructions.
If you make unauthorized changes to the system, the modules or
components, the explosion protection approval will also be terminated.
The diaphragm valves Types 2030, 2031, 2031 K, 2032,
2033 and 2037 were developed with due consideration
given to the accepted safety rules and are state-of-the-art.
Nevertheless, dangerous situations may occur.

Basic Safety Instructions
3. 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.
DANGER!
Danger – high pressure!
• Before loosening the lines and valves, turn off the pressure and
vent the lines.
Danger of bursting from overpressure!
• Observe the specifications on the type label for max. control
and medium pressure.
• Observe permitted medium temperature.
WARNING!
Risk of electric shock!
• Before reaching into the device or the equipment, switch off the
power supply and secure to prevent reactivation!
• Observe applicable accident prevention and safety regulations
for electrical equipment!
CAUTION!
Risk of burns/risk of fire if used continuously through hot
device surface!
• Keep the device away from highly flammable substances and
media and do not touch with bare hands.
WARNING!
General hazardous situations.
To prevent injury, ensure 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.
• Do not put any loads on the body (e.g. by placing objects on it
or standing on it).
• Do not make any external modifications to the device bodies. Do
not paint the body parts or screws.

5. SYSTEM DESCRIPTION
5.1. General Description
The Types 2030, 2031, 2031 K, 2032, 2033 and 2037 are an exter-
nally controlled diaphragm valve with piston drive and diaphragm seal.
The valve is self-draining in the appropriate installation position.
5.2. Intended Application Area
The diaphragm valve of Type 2030 is designed for the control of con-
taminated and aggressive media. The valves of Type 2031, 2031 K,
2032, 2033 and 2037 can be used even for ultra-pure or sterile media
with a higher viscosity.
The valves may only control media which do not attack the body and
seal materials (see type label). Information on the resistance of materials
to the media is available from your Bürkert sales office.
