3. Transport and storage
Shut-off butterfly valves with lining s must be caref ully hand le d, tran spor ted 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 shut-off 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 plastic lining, that is prone to scratching, 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 plastic-lined facings of the flanges intended to connect the valve to the pipeline are not
damaged through mechanical or other influe nce s. Do not sta ck shut-off butterfly valves!
As a rule, shut-off butterfly valves of the BR10a series and shut-off butterfly valves of the BR 10e series in the slightly open

4. Installation in the pipeline
4.1 General
The same instructions apply for installing the shut-off butterfly valves in the pipeline as for connecting pipes and similar pipeline
equipment. The following instructions additionally apply for shut-off butterfly valves. Also observe section 3 for transporting the
shut-off butterfly valve to the point of installation.
The valve is lined with PTFE:
Handle with special care and follow the instructions for flange connection.
The facings of the valve body are lined with plastic:
If additional flange gaskets are used, we recommend using gaskets made of PTFE.
The mating flanges must have smooth facings. Contact the manufacturer if you intend to use other flange forms.
The actuating device is set for the operating data specified in the order:
Do not alter the settings for the final positions OPEN and CLOSED without the manufact ur er’s prior con se nt.
pressure is not applied to these valves.
If an actuator unit has been mounted subsequently, torque, direction of rotation, operating angle as well as the
Danger
final positions OPEN and CLOSED must be adapted to the shut-off butterfly valve.
Failure to follow these safety precautions may result in personal injury and can damage equipment
The following warnings are to be observed for gears:
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 shut-off butterfly valve.
Gears that weigh more than the shut-off butterfl y valve:
Support any gears which due to its size and/or mounting situation would otherwise cause the valve to bend under
the load.
4.2 Installation instructions
Lined surfaces of the valve must be specially protected before/during installation:
Transport the valve in its original packaging right up to the point of ins
of installation.
Check valve and gear for signs of damage that may have occurred during transportation. Do not install a damaged shut-off
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 rouble sho otin g>.
Make sure that only shut-off butterfly valves are installed when their pressure rating, end connections and fac e to face
dimensions match the conditions of application. See the designation of the shut-off butterfly valve.
conditions. The limits of application are marked on the valve, see section 2.4 <Designation>. The permissible
range is determined in section 1 <Intended use>.
Danger
Failure to follow these safety precautions may result in personal injury and can damage equipment
Make sure the end connections of the pipeline are aligned with the shut-off butterfly valve’s end connections and their ends
have parallel planes. Connecting flanges that are not parallel can damage the PTFE lining during installation!

Warning
Prior to installation, carefully clean the valve and the connecting section of the pipeline from dirt, especially hard foreign
material.
Make sure, in particular, that flange facings and any flange gaskets used are free from any dirt prior to installation.
The valve must be inserted in the gap between the pipe flanges with the butterfly disc in the closed position.
Otherwise, the butterfly disc could be damaged and the valve will not shut tightly.
The inside diameter of the mating flanges must leave sufficient room for the
opened butterfly disc to ensure that it cannot be damaged on swinging out. See
Table 2.

The process medium can flow through the valve in either direction. The preferable mounting position for shut-off butterfly
valves is with a shaft in a horizontal position. However, if possible, the gear should not be located directly underneath the
shut-off butterfly valve.
Make sure the arrow on the valve body corresponds with the direction of flow in the pipeline.
In special cases, it may be necessary for the valve to be tightly shut against the direction of flow. 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.
Tighten the flange bolts evenly and in a criss-cross pattern in at least three steps. Tighten all flange bolts using
torques specified in Tables 2 or 3.
Use a torque wrench to ensure that the torque specified is reached, yet not exceeded.
Table 3 – Flange torques for DIN-Flanges
Table 4 – Flange torques for ANSI-Flanges
Since PTFE plastic facings have a tendency to creep, we strongly recommend after installation to retighten the
bolted joint of the valve body using the tightening torques in Table 2 if the valves have been in storage for a long
time.
5. Pressure check in pipeline section
The pressure check of valves has already been carried out by the manufacturer. To check the pressure of a section of pipeline
with installed valves, the following point s mus t be observ ed:

Valve OPEN: The test pressure should not exceed the value 1.5 x PN (see nameplate).
Valve CLOSED: The test pressure should not exceed the value 1.1 x PN (see nam epl ate) .
If a valve leaks, see section 7 <Troubleshooting>.
6. Standard operation and maintenance
Due to the fact of flowing plastic flange facings we strongly recommend to check flange bolt torques acc. to specified
figures in section 4.2 after commissioning and normal operation temperature has been reached.
The shaft is sealed with a V-ring packing preloaded with a set of spring washers and does not require any maintenance.
Normal manual force is sufficient to operate the manual override on the actuator (if required). It is not permissible to use
extensions to increase the operating torque.
The position of the lever indicates the valve’s position:
Lever at a 90° angle to the pipeline: Valve CLOSED,
