5.0 Installation
5.1 Warning of dangers during installation, operation and maintenance
DANGER!
Safe operation of the valve can only be guaranteed if it is installed, commissioned
and maintained by qualified personnel (see point 2.3 “Qualified staff“) correctly and
in observance of the warnings in this operating manual. Apart from that, the
operation safety order and the qualified use of tools and protection equipment must
be guaranteed. The operating instructions for the valve must be observed during all
work on or with the valve. Failure to observe these instructions may result in injury
or in damage to the valve or other installations.
When the valve is used as a final sealing element, a safety precaution e.g. blanking disc, blind flange,
etc., in accordance with the code of practice of the German Technical and Scientific Association for
Gas and Water (DVGW) is recommended during all repair work.
5.2 Installation
Apart from the general installation guidelines, the following points should be observed:
NOTICE!

Remove the flange covers.

The inside of the valve and the pipeline must be free from foreign particles.

Observe the installation position in relation to the flow direction, see markings
on the valve.

Centre gaskets between the flanges.

The connecting flanges must be aligned.

Ensure that none of the components is strained during installation.

The valve must not be used as a fixed point; it is supported by the pipework
system.

Protect valves from soiling, particularly during construction work.

Thermal expansion of the pipework must be equalized using compensators.
The valve can be installed with upright but not suspended solenoid drive. Valves with order suffix “W”
in the type designation can be installed with horizontal solenoid drive.
NOTICE!
Please observe the solenoid drive operating instructions (BTA).
6.0 Operation
DANGER!
Before commissioning a new installation or before starting up an installation again
after repairs or modifications, ensure:

The proper completion of all installation and assembly work!

Commissioning only by “qualified staff” (see point 2.3).

Installation or repair of existing guards and protection equipment.
