5.2 Function
Spring force (CFA) or pneumatic pilot pressure (CFB and CFI) gen-
erates the closing force on the diaphragm pressure piece. The force
is transferred via a spindle which is connected to the actuator piston.
5.2.1 Control functions (CF)
WARNING!
For control function I: Danger if pilot pressure fails.
For control function I (CFI) control and resetting occur pneumati-
cally. If the pressure fails, no dened position is reached.
▶To ensure a controlled restart, rst pressurize the device with
pilot pressure, then switch on the medium.

ensure self-drainage.
Installation for leakage detection
One of the bores in the diaphragm socket for monitoring
leakage must be at the lowest point.
7.1.1 Installation position Type 2063
Installation position: at will, preferably with the actuator upright.
To ensure self-drainage:
→Install body inclined by an angle α= 10° to 40° to the hori-
zontal.
Forged and cast body: Mark on the body must point upwards
(12 o’clock position, see “Fig. 7”).
→Observe an inclination angle of 1° to 5° to the line axis.
Angle α: 10° to 40°
Inclination to the line axis 1° to 5°

7.4 Installation of the valve body
WARNING!
Risk of injury from improper installation.
▶Installation may only be performed by qualified and trained
personnel.
▶For installation use an open-end wrench.
▶Observe the tightening torque.
7.4.1 Installation 2-way body and T-valve body
Welded bodies
→Weld valve body in pipeline system.
Other bodies
→Connect body to pipeline.
7.4.2 Welding tank bottom body type 2065
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 valve body into the pipeline.

Installation
english
Type 2063, 2064, 2065

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 indi-
cated 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.
1. Welding tank bottom body onto the tank:
ATTENTION!
Before welding, note the following:
▶Use only welding material which is suitable for the tank
bottom 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.
7.5 Installation of the actuator (welded
body)
NOTE!
Damage to the diaphragm or the seat contour.
▶When installing the actuator, ensure that the valve is open.
Installation for actuator with control function A:
→Pressurize the pilot air port 1 with compressed air: valve
opens.
→Lightly cross-tighten the body screws until the diaphragm is
between the valve body and actuator.
Do not tighten the screws yet.
→Actuate the diaphragm valve twice.
→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 ( see “Tab. 1”). The diaphragm should be
positioned and pressed evenly all around the actuator and body.

7.6 Pneumatic connection
WARNING!
Risk of injury from unsuitable connection hoses.
▶Use only hoses which are authorized for the indicated pressure
and temperature range.
▶Observe the data sheet specifications from the hose
manufacturers.
For control function I: Danger if pilot pressure fails.
For control function I control and resetting occur pneumatically.
If the pressure fails, no dened position is reached.
▶To ensure a controlled restart, rst pressurize the device with
pilot pressure, then switch on the medium.
7.6.1 Connection of the control medium
Control functions A and B
→Connect the control medium to the pilot air port 1 of the
actuator
(see “Fig. 10: Pneumatic connection”).
Control function I
→Connect the control medium to the pilot air port 1 and 2 of
the actuator (see “Fig. 10: Pneumatic connection”)
Pressure on connection 1 opens the valve.
Pressure on connection 2 closes the valve.
If used in an aggressive environment, we recommend
conveying all free pneumatic connections into a neutral
atmosphere with the aid of a pneumatic hose.

8 REMOVAL
DANGER!
Risk of injury from discharge of medium and pressure.
It is dangerous to remove a device which is under pressure due
to the sudden release of pressure or discharge of medium.
▶Before removing a device, switch o the pressure and vent
the lines.
→Loosen the pneumatic connection.
→Remove the device.
9 MAINTENANCE WORK
9.1 Actuator
The actuator of the diaphragm valve is maintenance-free pro-
vided it is used according to these operating instructions.
9.2 Wearing parts of the diaphragm valve
Parts which are subject to natural wear:
•Seals
•Diaphragm
→If leaks occur, replace the particular wearing part with an
appropriate spare part.
A bulging PTFE diaphragm may reduce the ow.
9.3 Inspection intervals
The following maintenance work is required for the diaphragm valve:
→After the rst steam sterilization or when required retighten
body screws crosswise.
→After maximum 105switching cycles check the diaphragm for
wear and replace if required.
Muddy and abrasive media require correspondingly
shorter inspection intervals!
