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>.
conditions specified in the data sheets <TB14a, TB14b, TB14e, TB14t, TB74b, DB14b-07 and DB14p-01>.
Danger
Observation of conformity with the Directive 2014/34/EU.
Failure to follow these safety precautions may result in personal injury and can damage equipment
DIN EN 13463-1. Therefore Pfeiffer valves do not come under the directive 2014/34/EU.
Note
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.
Relating to this directive a CE-marking is not permissible. The valve could be incorporated into potential
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.
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.

Keep the labeling on the valve body and on the nameplate to ensure that the valve can be identified at all times.
3. Transport and storage
Butterfly valves must be carefully handled, transported and stored:
Store the valve with its protective packing and/or with its protective caps in place in the end connections. Store and
transport the butterfly valves that weigh over approx. 10 kg on pallets (or a similar type of support) right up to the point of
installation. The packing is designed to protect the valve’s internal parts against being damaged.
Store the valve in a closed room before it is installed. Protect it against damaging influences such as dirt or moisture.
Make sure, in particular, that the facings of the flanges are not damaged through mechanical or other influences. Do not
stack butterfly valves!
As a rule, butterfly valves are delivered in the closed position. Store the valves in the condition they were delivered in. Do
not operate the valve.
4. Installation in the pipeline
4.1 General
The same instructions apply for installing the butterfly valves in the pipeline as for connecting pipes and similar pipeline
equipment. The following instructions additionally apply for butterfly valves. Also observe section 3 for transporting the butterfly

Warning
The following warnings are to be observed for Gears:
The following warnings are to be observed for high-performance butterfly valves including a seat with metal sealing:
Failure to follow these safety precautions may result in personal injury and can damage equipment
Gears are not designed to be used as step-ladders:
Do not apply any weight/load to the gears. This can damage or destroy the butterfly valve.
Gears that weigh more than the butterfly valve:
Support any gears which due to its size and/or mounting situation would otherwise cause the valve to bend under
the load.
To avoid that the seat seal is damaged, make sure the pipeline upstream and dow nstream of the place of
installation is carefully cleaned from all hard and abrasive foreign material prior to installation of the butterfly valve.
4.2 Installation instructions
Store and transport the valve with its protective packing right up to the point of installation.
Check valve (and gear) for signs of damage that may have occurred during transportation. Do not install a damaged
butterfly valve.
Prior to installation, carry out a function check. The valve must open and close properly. Any function errors that are
recognized must be remedied before commis sio ning . See als o secti on 7 <T roubleshooting>.
Make sure that only butterfly valves are installed when their pressure rating, end connections, (flow rate) and face to face
dimensions match the conditions of application. See the designation of the butterfly valve.

The valve must be inserted between the pipeline flanges with the butterfly disc in closed position.
Otherwise, the disc might be damaged and the valve could become leaky.
The inside diameter of the mating flanges must leave sufficient room for the opened

Make sure the arrow on the valve body corresponds with direction of pressure in the pipeline.
In special cases, it may be necessary for the valve to be tightly shut against the pressure direction. The installation
in such special cases must be determined by the operator of the pipeline (e.g. to protect a pump).
On inserting the valve (and flange gaskets) into a ready mounted pipeline, keep a certain clearance between the pipeline
ends to ensure that all facings (and gaskets) remain undamaged.
For butterfly valves with re-adjustable stuffing box:
The necessary torques for tightening the adjustable stuffing box can taken for table 3.
The use of torque wrenches ensure, that the torques are reached.
