5 TECHNICAL DATA
5.1 Conformity
The diaphragm valve Type 2031 INOX is compliant with the EC Direc-
tives according to the EC Declaration of Conformity.
5.2 Standards
The applied standards which are used to demonstrate compliance with
the EC Directives are listed in the EC type test certificate and/or the
EC Declaration of Conformity.
5.3 Operating conditions
5.3.1 Temperature ranges
Ambient temperature: 0 °C … +60 °C
Medium temperature: -10 °C … +140 °C
Permitted medium temperature depending on diaphragm material:
Diaphragm
material
Medium
temperature 1)
Remark
EPDM -10 ... +130 °C Steam sterilization up to 140 °C
PTFE / EPDM -10 ... +130 °C Steam sterilization up to 140 °C
Laminated
advanced PTFE
-10 ... +90 °C -
1)
The specified medium temperature applies only to media which does not
attack diaphragm materials. The behavior of the medium with respect to the
diaphragm may be changed by the temperature of the medium.
The functional characteristics, in particular the service life of the diaphragm,
may be impaired as the temperature of the medium rises.

DANGER!
Danger – high pressure!
▶Before dismounting the lines and valves, turn off the pressure and
vent the lines.
Risk of electric shock!
▶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!
Risk of injury from improper installation, unintentional activation
of the system and uncontrolled restart!
▶Installation must only be carried out by authorized technicians and
with the appropriate tools!
▶Secure system from unintentional activation.
▶Following installation, ensure a controlled restart.
Risk of crushing from moving pneumatic connection!
▶When opening and closing the device, do not touch the moving
pneumatic connection.
▶Do not reach into the area immediately above and below the
control air connection.
6.1 Before installation
• Before connecting the valve, ensure the lines are flush.
• The flow direction is optional.
6.1.1 Installation position
Installation position: any, preferably with the actuator face up.
Installation for self-drainage of the body:
It is the responsibility of the installer and operator to ensure
self-drainage.
To ensure self-drainage:
• mark (-) on the body must be at 12 o’clock,
• hole in the diaphragm base must be at the lowest point to monitor
leakage.
Drainage angle -2°

Installation
Type 2031 INOX
Devices with VG/VS welded body
Before welding the body, the actuator must be removed.
6.2 Installation
WARNING!
Risk of injury from incorrect installation!
Non-observance of the specified tightening torque is hazardous
as the device may be damaged.
▶Observe tightening torque during installation.
6.2.1 Devices with VG/VS welded body
Before welding the body, the actuator must be removed.
Remove actuator and diaphragm from the body
Procedure for control function A:
→Apply control air connection with compressed air (5.5 bar).
→Loosen fastening screws in diagonal pairs and remove actuator
together with diaphragm from the body.
→Weld body into the pipeline.
Procedure for control function B:
→Loosen fastening screws in diagonal pairs and remove actuator
together with diaphragm from the body.
→Weld body into the pipeline.
6.2.2 Installation
Installation for actuator with control function A:
→Align diaphragm.
The mark tab of the diaphragm must be vertical to the flow
of direction.
→Place actuator on the body.
→Apply control air connection with compressed air (5.5 bar).
→Lightly tighten fastening screws crosswise until the diaphragm is
situated between the body and actuator.
Do not tighten screws yet!
→Switch diaphragm valve twice.
→Tighten fastening screws.
Observe tightening torque (2.5 Nm)!

6.3 Pneumatic connection
WARNING!
Risk of injury from unsuitable connection hoses!
Hoses which cannot withstand the pressure and temperature range
may result in hazardous situations.
▶Use only hoses which are authorized for the indicated pressure
and temperature range.
▶Observe the data sheet specifications from the hose manufacturers.
6.3.1 Control air connections
The 45° angle connection, which can be ordered
separately, is recommended for the control air con-
nection! In this case the free-moving hose length
should be min. 250 mm. If the hose length is shorter,
the durability and function of the plug-in coupling
will be impaired!
If a straight control air connection is used, the free-
moving hose length should be min. 400 mm.
If the hose length is shorter, the durability and
function of the plug-in coupling will be impaired!
Risk of crushing!
▶Due to the risk of crushing, a 90° control air con-
nection must not be used!
7 START-UP
WARNING!
Risk of injury from improper operation!
Improper operation may result in injuries as well as damage to the
device and the area around it.
▶Before start-up, ensure that the operating personnel are familiar
with and completely understand the contents of the manual.
▶Observe the safety instructions and intended use.
▶Only adequately trained personnel may start up the device.
Observe the type label specifications and information on pressure
and temperature values in chapter “Technical data”.
8 MAINTENANCE, CLEANING
8.1 Actuator
The actuator of the diaphragm valve is maintenance-free provided it is
used according to these operating instructions.
8.1.1 Wearing parts of the diaphragm valve
Parts which are subject to natural wear:
• Diaphragm
→If leaks occur, replace the diaphragm with a new one.
A distended PTFE diaphragm may reduce the flow-rate.

Transportation, Storage, Disposal
Type 2031 INOX
8.1.2 Inspection intervals
→Check diaphragm for wear after a maximum 105 switching operations.
Muddy and abrasive media require correspondingly shorter
inspection intervals!
8.2 Cleaning
Commercially available cleaning agents can be used to clean the
surface of the device.
NOTE!
Before cleaning, check that the cleaning agents are compatible
with the body materials and seals.
9 TRANSPORTATION, STORAGE,
DISPOSAL
NOTE!
Transport and storage damage!
• Protect the device against moisture and dirt in shock-resistant
packaging during transportation and storage.
• Permitted storage temperature: -20 … +65 °C.
Storage with tightened body screws may result in permanent
deformation of the diaphragm.
• Slacken body screws for prolonged storage.
Damage to the environment caused by device components
contaminated with media.
• Dispose of the device and packaging in an environmentally
friendly manner!
