▶Correct transportation, correct storage and installation and
careful use and maintenance are essential for reliable and
faultless operation.
▶Use the device only as intended.
3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not consider any contingencies or
incidents which occur during installation, operation and main-
tenance. The operator is responsible for observing the location-
specicsafetyregulations,alsowithreferencetothepersonnel.
DANGER!

surface of the device to become hot.
▶Only touch the device while wearing protective gloves.
▶Keepthedeviceawayfromhighlyammablesubstancesand
media.
Leaking medium when the diaphragm is worn.
▶Regularly check relief bore for leaking medium.
▶If medium is leaking out of the relief bore, change the diaphragm.
▶If the media is hazardous, protect the area surrounding the
discharge point against dangers.
General hazardous situations.
To prevent injury, ensure:
▶That the system cannot be activated unintentionally.
▶Only trained technicians may perform installation and mainte-
nance work.
▶Perform installation work and maintenance work using suitable
tools only.
▶Do not transport, install or remove heavy devices without the aid
ofasecondpersonandusingsuitableauxiliaryequipment.
▶After an interruption, ensure that the process is restarted in a
controlledmanner.Observesequence!
1. Apply supply voltage or pneumatic supply.
2. Charge the device with medium.
▶The device may be operated only when in perfect condition and
in consideration of the operating instructions.
▶Observethesafetyregulationsspecictotheplantforapplication

5 SYSTEM DESCRIPTION
5.1 General description
The Types 2030, 2031, 2032, 2033 and 2037 are an externally con-
trolled 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
contaminated and aggressive media. The valves of Type 2031,
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).

7.2 Function
Spring force (CFA) or pneumatic control pressure (CFB and CFI)
generates the closing force on the diaphragm pressure piece. The
force is transferred via a spindle which is connected to the actuator
piston and the valve is opened and closed.

DANGER!
Risk of injury from high pressure in the equipment.
▶Beforelooseningthelinesandvalves,turnothepressureand
vent the lines.
Risk of injury due to electrical shock.
▶Beforereachingintothedeviceortheequipment,switcho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.
▶Installation may be carried out by authorized technicians only
and with the appropriate tools.
Risk of injury from unintentional activation of the system and an
uncontrolled restart.
▶Secure system from unintentional activation.
▶Following assembly, ensure a controlled restart.
CAUTION!
Risk of injury due to 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.
8.1 Installation position 2/2-way valve
• The piston-controlled diaphragm valve can be installed in any
installation position, preferably with the actuator face up.
Installation for leakage detection
One of the bores in the diaphragm socket, for moni-
toring leakage must be at the lowest point.
To ensure self-draining
It is the responsibility of the installer and operator to
ensure self-draining.
Self-drainingmustbeconsideredduringtheinstallation:
• Inclinationangleofthepipeline:
The inclination angle is the responsibility of the installer and
operator and should correspond to the inclination angle of the
pipeline.
For the pipeline, we recommend the inclination angle
according to the valid ASME BPE.
• Self-drainage-angleforvalvebody:
The self-drainage-angle (α) depends on the valve body size (dia-
phragm size) and the inner diameter of the port connection (DN).
 Theself-drainageangleisspeciedasavalueonforgedsteel
valve bodies (VS) and tube valve bodies (VP) (see “Fig.2” and
“Fig.3”).
The marking on the port connection of valve bodies serves as an
orientation aid (see “Fig.13”). The marking must point upwards.

8.2 Installation position of T-valve
type 2032
Installation for leakage detection
One of the bores in the diaphragm socket, for moni-
toring leakage must be at the lowest point.
For the installation of the T-valves into circular pipelines, we rec-
ommendthefollowinginstallationpositions:

Installation
8.4 Installation into the pipeline
8.4.1 Preparatory work
→Clean pipelines (sealing material, swarf, etc.).
→Support and align pipelines.
8.4.2 Installation requirements
• Ensure that pipelines are in alignment.
• Flowdirectionasrequired.
If used in an aggressive environment, we recommend
conveying all free pneumatic connections into a neutral
atmosphere with the aid of a pneumatic hose.
8.4.3 Weld or glue the valve body into the
pipeline
Before welding or gluing the body, the actuator and the
diaphragm must be removed.
Theinstallationisdividedintothefollowingsteps:
1. Disassemble actuator and diaphragm, see chapter “8.5”
2. →Weld or glue the valve body into the pipeline.
→After welding or gluing in the body, smooth the valve
bodysurfacebygrindingifrequired.
→ Carefully clean the body.
3. Mount the actuator and diaphragm, see chapter “8.6”.
8.4.4 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, we recommend the
inclination angle according to the valid ASME BPE.
DANGER
Risk of injury from high pressure.
▶Before working on the system, switch off 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 certificate 3.1.

Installation
Observe the applicable laws and regulations of the
respectivecountrywithregardtothequalificationof
welders and the execution of welding work.
1. Welding tank bottom body onto the tank.
NOTE
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
installation 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, see chapter “8.6”.
8.5 Removing the actuator and
diaphragm from the valve body
8.5.1 Procedure for control function A
→Pressurize lower pilot air port with compressed air (value as
indicated on the type label) (see “Fig.17”).
Thisisrequiredtodetachthediaphragmwithoutdamagefrom
the body.
→Loosen fastening screws crosswise and remove actuator
together with diaphragm from the valve body.
8.5.2 Procedure for control functions B and I
→Loosen fastening screws crosswise and remove actuator
together with diaphragm from the valve body.
8.6 Mounting the actuator and
diaphragm on the valve body
WARNING!
Risk of injury due to damaged device or malfunction.
Thefailuretoobservethetighteningtorquecandamagethe
device or lead to malfunctions.
▶Observethetighteningtorque (see “Tab.7:Tighteningtor-
quesfordiaphragms”).
