• When planning the application of the device, and during its operation,
observe the general technical rules!

• Work on the device should only be carried out by specialist staff using
suitable tools!

english

• Please note: Piping or valves should not be removed from a system which is
under pressure!

• Always switch off the voltage supply before working on the system!

• Take suitable measures to prevent unintentional operation or impermissible
impairment.

• If these instructions are ignored, or if inadmissible work is carried out on the

Continual pressure surges can shorten the service life of the
diaphragm!

3 INSTALLATION AND COMMISSIONING

3.1 Installation

Î Before installing the valve, clean the piping system!

Î Where necessary, fit a strainer upstream to protect against faults!

Î Observe the direction of flow!

Î Seal the thread using PTFE tape.

Î When installing the valve, ensure that the valve block is not distorted:

- provide adequate support for the piping system

- align the piping system

• Maximum permissible torque Mt:
for G 3/4" connections from plastic:
4 Nm

• Maximum permissible bending moment MB:
for all connections:
6 Nm

ATTENTION!

4 - 6227

Do not use the pilot valve as a lever when screwing in the
pipe connection!

Do not distort the valve housing during the installation!

Max. ambient temperature for continuous operation: +55 °C!

3.2 Electrical connection

• The voltage, electrical power, pressure range and nominal width can be
found on the name plate.

• Voltage tolerance: ± 10%

• Electrical connection: Instrument socket Type 2508 to the connection plug pin
of the coil; Fixing torque: 0.5 Nm

ATTENTION!

Î Ensure that the maximum operating conditions (see

name plate) are not exceeded!

Î Always connect the protective conductor!

Î Always follow the warning instructions on the coil,

particularly for coils which require rectifiers!

Î When screwing the coil and the instrument socket

together, ensure that the seal is properly seated!

3.3 Measures to be taken before installation

Î Before the installation, check:

- fluid and electrical connections

- Operational pressure

- Voltages

- Type of current.
