1) The indicated medium temperatures apply only to media which do not
corrode or swell the diaphragm materials. The behavior of the medium
with respect to the diaphragm may be changed by the medium tem-
perature. The function properties, in particular the service life of the
diaphragm, may deteriorate if the medium temperature increases. Do
not use the diaphragms as steam shut-o element.

7 INSTALLATION
DANGER!
Danger – high pressure.
▶Turn o the pressure and vent the lines before loosening
lines or valves.
Risk of electric shock.
▶Before reaching into the device or the equipment, switch o
the power supply and lock to prevent reactivation.
▶Observe applicable accident prevention and safety regula-
tions for electrical equipment.
WARNING!
Risk of injury from incorrect installation.
▶Installation may only be performed by authorized technicians
with the appropriate tools.
Risk of injury from unintentional activation of the system and
uncontrolled restart.
▶Secure system against unintentional activation.
▶Following installation, ensure a controlled restart.
CAUTION!
Risk of injury due heavy devices!
▶During transport or during assembly, a heavy device may fall
and cause injury.
▶Do not transport, install or remove heavy devices without the
aid of a second person and using suitable auxiliary equipment.
▶Use appropriate tools.
7.1 Before installation
•Before connecting the valve, ensure that the pipelines are
aligned.
•The ow direction is optional.
7.1.1 Installation position general
Installation for self-drainage of the body
It is the responsibility of the installer and operator to
ensure self-drainage.
Installation for leakage detection
One of the bores in diaphragm socket for monitoring
leakage must be at the lowest point.
7.1.2 Installation position 2/2-way valve
Installation position: any position, preferably with the actuator
face up.
To ensure self-drainage:
→Install body at an angle α= 10° to 55° to the horizontal
(see “Fig. 2”).
→Observe an inclination angle of 1° – 5°.
→Forged bodies, tube valve bodies and cast bodies feature
a mark which must face upwards ( (12 o'clock position, see
“Fig. 2”).
→One of the bores in the diaphragm socket for monitoring
leakage, must be at the lowest point.

Fig. 4: Installation position of Type 2037
7.1.5 Welding tank bottom body type 2033
Recommendation
Observe sequence:
1. Weld the tank bottom body onto the base of the tank
before installing the tank. Welding onto a tank which has
already been installed is possible but more dicult. Weld
the tank bottom body in the middle of the tank base so that
the tank can be optimally drained.
2. Weld tank bottom body into the pipeline.
Installation requirements:
Pipelines: Ensure that the pipelines are aligned.
Preparation: Support and align pipelines. To ensure that the
pipeline is self-draining, observe an inclination angle
of 1°...5°.
DANGER
Risk of injury from high pressure.
▶Before working on the system, switch o the pressure and
vent or drain lines.
For information on tanks and instructions on welding
observe the standard ASME VIII Division I.
Before you start welding, check the batch number indicated
on the supplied manufacturer’s certicate 3.1.
Observe the applicable laws and regulations of the
respective country with regard to the qualication of
welders and the execution of welding work.

Installation
1. Welding tank bottom body onto the tank.
NOTE
Before welding, note the following:
▶Use only welding material which is suitable for the tank bot-
tom body.
▶The tank bottom valve must not collide with any other instal-
lation part; the actuator must be easy to install and remove.
2. Welding tank bottom body into the pipeline.
→Weld in tank bottom body.
Ensure installation is de-energized and low-vibration.
After welding in the valve body.
Install the diaphragm and the actuator.
7.1.6 Preparatory work
→Clean pipelines (sealing material, swarf, etc.).
→Support and align pipelines.
Devices with welded or bonded body:
Before welding or bonding the body, the actuator and
diaphragm must be removed.
7.2 Installation
If used in a corrosive environment, we recommend running
a pneumatic hose from all free pneumatic connections to
a neutral atmosphere.
WARNING!
Risk of injury from incorrect installation.
Non-observance of the specied tightening torque is haz-
ardous as the device may be damaged.
▶Observe tightening torque during installation (see “Tab. 2:
Tightening torques in Nm for diaphragms”).
7.2.1 Devices with welded or bonded body
NOTE!
To avoid damage!
Before welding or bonding the body, the actuator and
diaphragm must be removed.
Remove actuator and diaphragm from the body:
Procedure for control function A
→Pressurize the lower control air connection with compressed air
(value on type label) (see “Fig. 5: Control air connection”).
This is required so that the diaphragm detaches from the
body and is not damaged.
→Loosen fastening screws in diagonal pairs and remove actuator
together with diaphragm from the body.
→Weld or glue body into the pipeline.
Procedure for control functions B and I
→Loosen fastening screws in diagonal pairs and remove actuator
together with diaphragm from the body.
→Weld or glue body into the pipeline.
Mount actuator and diaphragm on the body:
→After welding or bonding the body, smooth the body surface
by grinding if required.
→Carefully clean the body.

Installation
Procedure for control function A
→Pressurize the lower control air connection with compressed
air (value on type label) (see “Fig. 5: Control air connection”).
→Place actuator on the body.
→Lightly cross-tighten the body screws in diagonal pairs until
the diaphragm lies between the body and actuator.
Do not fully tighten screws yet.
→Actuate the diaphragm valve twice to position the diaphragm
correctly.
→Tighten body screws without pressurization in diagonal pairs
in three stages (approx. 1/3, approx. 2/3, 3/3 of the tightening
torque), according to Table (“Tab. 2: Tightening torques in Nm
for diaphragms”). The diaphragm should be positioned and
pressed evenly all around the actuator and body.
Procedure for actuator with control functions B and I:
→Place actuator on the body.
→Lightly cross-tighten the body screws in diagonal pairs
without pressurization until the diaphragm is between the
body and actuator. Do not fully tighten screws yet.
→Pressurize the upper control air connection with compressed
air (value on type label) (see following “Fig. 5: Control air
connection”).
→Actuate the diaphragm valve twice.
→Tighten body screws with pressurization in diagonal pairs in
three stages (approx. 1/3, approx. 2/3, 3/3 of the tightening
torque), according to Table (“Tab. 2: Tightening torques in Nm
for diaphragms”). The diaphragm should be positioned and
pressed evenly all around the actuator and body.
