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.
In case of use of the valve as sealing end, we recommend safety measures like for example blanks, blind
flanges, etc. in case of maintenance 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.
According to DIN EN ISO 23553-1 a dirt catcher must be installed in front of every safety lock valve. The
mesh diameter inside of the sieve must be 0.5 mm. In case of two safety lock valves combined it is
sufficient to install one dirt catcher in front of the first valve. The dirt catcher must be installed in a not too
far distance from the first valve. The UNI-Geräte dirt catchers of the SFR series are permitted for the use
of flange valve.
The valve can be installed with vertical or horizontal, but not suspended 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.
6.1 Commissioning
Before commissioning, check the data on material, pressure, temperature and flow direction
with the layout plan of the pipework system.
Depending on the field of application, the local regulations have to be observed, e.g. the
operation safety order.
Residues in the pipework and the valve (dirt, weld beads, etc.) will inevitably result in leaks.
Leakage inspection of the installed valve.
6.2 Shutting
