and
CAUTION
notes must be strictly adhered to. Otherwise this may lead to personal injury and
equipment damage and the manufacturer’s warranty may become void.

1. Intended use
After installing the valve in the pipeline, manually operated butterfly valves are designed exclusively for shutting off or controlling
media (often corrosive) within the permissible pressure and temperature ranges.
The permissible pressure and temperature ranges for these butterfly valves are specified in the data sheets <
TB14a
,
TB14b
,
TB14e
,
TB14t
,
TB74b
,
DB14b-07
and
DB14p-01
>.
Danger
Do not operate a butterfly valve when its permissible pressure/temperature rating is not sized for the operating
conditions specified in the data sheets <
TB14a
,
TB14b
,
TB14e
,
TB14t
,
TB74b
,
DB14b-07
and
DB14p-01
>.
Failure to follow these safety precautions may result in personal injury and can damage equipment
installed in the pipeline.
Observation of conformity with the Directive 2014/34/EU.
Note
Pfeiffer valves have no own potential ignition source after testing the hazardous ignition in accordance to
DIN EN 13463-1. Therefore Pfeiffer valves do not come under the directive 2014/34/EU.
Relating to this directive a CE-marking is not permissible. The valve could be incorporated into potential
compensation of plants independent of the directive, valid for metallic parts in hazardous areas.
Refer to the limitations in the above mentioned data sheets if the butterfly valve is intended for throttling services.
Parts subject to wear are not covered by the warranty.
Observance of section 2 <Safety instructions> is presumed for the Intended use.
2. Safety instructions
2.1
General safety instructions
For butterfly valves, the same safety regulations apply as for the pipelines in which they are installed. These instructions only
specify those safety instructions which need to be additionally observed concerning butterfly valves.
2.2
Safety instructions for the operator
The manufacturer does not assume any responsibility. Therefore, when using the butterfly valve, make sure the following
instructions are observed:
The valve is to be used only for its intended use as described in section 1.
Warning
Preventing misuse of the butterfly valve:
It is especially important to make sure that the wetted parts in the butterfly valve are suitable for the media used as
well as the prevailing pressures and temperatures.
Failure to follow these safety precautions may result in personal injury and can damage equipment
installed in the pipeline. The manufacturer does not assume any final responsibility.
