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:

Material Temperature

[°C]1)

Remarks

EPDM (AB) -10...+130 Steam sterilization up to +140 °C / 60 min

EPDM (AD) -5...+143 Steam sterilization up to +150 °C / 60 min

FKM (FF) 0...+130 No steam / dry heat up to +150 °C /

60 min

PTFE (EA) -10...+130 Steam sterilization up to +140 °C / 60 min

Advanced

PTFE (EU)

-5...+143 Steam sterilization up to +150 °C / 60 min

Gylon (ER) -5...+130 Steam sterilization up to +140 °C / 60 min

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-off element.

6 INSTALLATION

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°

Fig. 3: Installation position for self-drainage of the body

6.1.2 Preparatory work

→Clean pipelines (sealing material, swarf, etc.).

→Support and align pipelines.

english

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:

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.

english

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!
