0. Introduction
These instructions are designed to assist the user during installation, operation and maintenance of PFA/PTFE-lined control
valves from the BR1a,BR1b,BR1c,BR1z,BR6a and BR8a.
These instructions apply only to the control valve itself. In addition, refer to the instructions of the mounted actuator.
Note
The WARNING 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.
Please contact the manufacturer if you have any queries, see section 8 for contact address.
1. Intended use
After installing the valve in the pipeline and connecting the actuator to the control equipment, these control 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 control valves are specified in the data sheets <TB01a, TB01b,
TB01c, TB01z, TB06a and TB08a>.
Danger
Do not operate a control valve when its permissible pressure/temperature rating is not sized for the operating
conditions specified in the data sheets <TB01a, TB01b, TB01c, TB01z, TB06a and TB08a>.
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 do not have their own potential ignition source according to the risk assessment in the rare
incident of an operating fault in accordance with DIN EN 13463-1 and therefore do not fall within the scope of the
Directive 2014/34/EU.
Relating to this directive, CE marking is not permissible. The integration of valves into the equipotential bonding
of a plant applies to all metallic parts in hazardous areas regardless of the directive.
Valves with plastic lining (PFA, PTFE) in applications with chargeable media have to be lined with conductive
plastic lining with a surface resistance less than 1 Gigaohm (109Ohm) in accordance with paragraph 6.7.5a of
DIN EN 13463-1.
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 control valves, the same safety regulations apply as for the pipelines in which they are installed, as well as for the control
equipment connected to the actuator. These instructions only specify those safety instructions which need to be additionally
observed concerning control valves.
Additional safety instructions are specified in the instructions for the actuator assemblies.
2.2 Safety instructions for the operator
The manufacturer does not assume any responsibility. Therefore, on using the control valve, make sure the following
instructions are observed:
The valve is to be used only for its intended use as described in section 1.

4 of 9
Specifications subject without notice
Edition:
August 2017 Operating instructions BA 01a-01_
EN
Warning
Preventing misuse of the control valve:
It is especially important to make sure that the selected lining for wetted parts in the control valve is 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.
Danger
The valve should only be operated and serviced by personnel appropriately qualified for pressurized
pipelines.
Skilled staff in the sense of these operating instructions is persons who, as a result of their training, their
knowledge and their experience, as well as their knowledge of the relevant standards, are able to judge the tasks
assigned to them and are able to recognize possible dangers.
An actuator unit mounted subsequently onto the valve must fit the control valve properly and its final positions, especially
the closed position, need to be correctly adjusted.
Make sure that the pipeline and control equipment have been installed correctly and are checked at regular intervals. The
valve body wall thickness must be designed to take into account an additional load Fz in the usual order
(Fz = π/4•DN²•PS) for a correctly sized pipeline.
The valve needs to be connected correctly to the pipeline and to the control equipment.
Make sure the usual flow velocities are not exceeded in continuous service in this pipeline. Exceptional operating
conditions such as oscillations, water hammering, cavitation and large proportions of solid matter in the process medium,
especially abrasive, must be clarified beforehand with the manufacturer.
Warning
We recommend to open and close the valve regularly. Depending on the valve model, we recommend opening
and closing the valve at least once a year.
Depending on how long the valve remains in one position, breakaway and operating torques may differ
considerably than those specified in the data sheet. To take t
his matter into account on sizing the actuator, specify
how long the valve is to remain in the same position in your inquiry.
When the actuator is mounted subsequently onto the valve by the operator, the manufacturer does not assume
any final responsibility for the correctness of the actuator sizing regarding how long the valve is to remain in one
position.
Control valves that are operated at temperatures greater than +50°C or lower than -20°C must be protected, together with
the pipeline connections, against being touched.
Danger
Do not insert your hand into the valve while it is being tested not yet installed into the pipeline. Otherwise, serious
injuries may occur.
2.3 Particular hazards
Danger
Prior to removing the control valve from the pipeline, relieve pressure entirely in the pipeline to ensure the
process medium cannot escape uncontrollably from the pipeline.
Warning
Should it be necessary to remove a control valve from the pipeline, process medium may escape from the pipe or
out of the contr
ol valve. In the case of process media that can damage health or are dangerous, drain the pipeline
completely before removing the control valve from the pipeline.
Take special care concerning any remaining media that may still be in the pipeline or have collected in
the cavities of the valve.
Warning
Only unscrew or loosen any screws or bolts connecting the body parts after the valve has been removed from the
pipeline. Tighten the screws on reassembly with a torque wrench according to the instructions <EB01a,EB01b,
EB01c,EB01z,EB06a or EB08a>.
Warning
For control valves intended for dead-end service:
During standard operation, in particular, with gases or hot and/or dangerous media, mount a blank flange at the
free end connection or ensure that the control valve is properly protected against unauthorised operation.

Warning
If a control valve used for dead-end service must be opened in a pressurized pipeline, special care must be taken
to ensure that any process media escaping under pressure does not cause any damage.
Take into consideration that in most cases the process medium is a dangerous substance!
Warning
For control valves, Series 1a with an optional discharge bore:
The discharge bore with thread, can be found in the valve body, where the name plate is attached. If the PTFE-
Liner tears or rips, the product medium, which in most cases is toxic, and extreme reactive, can immediately
discharge from this bore. For this reason, the discharge bore must be:
a) sealed with the an existing plug screw.
b) connected to an appropriate piping, so that any immediate threat of danger is prevented.
Take into account, that in most cases the medium concerned is always dangerous!

Keep the labelling on the valve body and on the nameplate to ensure that the valve can be identified at all times.
3. Transport and storage
Control valves with linings 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 control 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 in the pipeline are not
damaged through mechanical or other influences. Do not stack control valves!
As a rule, control valves are delivered in the completely closed position. Store the valves in the condition they were
delivered in. Do not operate/activate the actuating device.
4. Installation in the pipeline
4.1 General
The same instructions apply for installing the control valves in the pipeline as for connecting pipes and similar pipeline
equipment. The following instructions additionally apply for control valves. Also observe section 3 for transporting the control
valve to the point of installation.
Caution
The valve is lined with PTFE/PFA:
Handle with special care and follow the instructions for flange connection.
Note
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.
Warning
If an actuator unit has been mounted subsequently, torque, direction of rotation, operating angle as well as the
final positions OPEN and CLOSED must be adapted to the control valve.
Failure to follow these safety precautions may result in personal injury and can damage equipment
installed in the pipeline.
Warning
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 manufacturer’s prior consent.
Warning
Only for control valves with electric actuator:
Make sure that the actuator is switched off in the CLOSED position by the torque switch’s signal. In the OPEN
position, the actuator must be switched off by the limit switch’s signal.
See the instructions for the electric actuator for further details.
The following warnings are to be observed for actuators:
Warning
Actuators are not designed to be used as step-ladders:
Do not apply any weight/load to the actuators. This can damage or destroy the control valve.
Warning
Actuators that weigh more than the control valve:
Support any actuator which due to its size and/or mounting situation would otherwise cause the valve to bend
under the load.
4.2 Installation instructions
Caution
The lined surface of the valve must be specially protected before/during installation:
Transport the valve in its original packaging right up to the point of installation. Remove packaging first at the
point of installation.
Check valve and actuator for signs of damage that may have occurred during transportation. Do not install a damaged
control valve or actuator.

01_EN
Make sure that only control valves are installed when their pressure rating, end connections and face to face dimensions
match the conditions of application. See the designation of the control valve.
Danger
Do not install a control valve if its permissible pressure/temperature ranges do not apply to the operating
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>.
Failure to follow these safety precautions may result in personal injury and can damage equipment
installed in the pipeline.
Make sure the end connections of the pipeline are aligned with the control valve’s end connections and their ends have
parallel planes. Connecting flanges that are not parallel can damage the PFA/PTFE lining during installation!
The connecting specifications for the actuator unit must match those of the control equipment. See nameplate(s) on the
actuator unit.
Prior to installation, carefully clean the valve and the connecting section of the pipeline from dirt, especially hard foreign
material.
The valve can be installed in any position. However, if possible, the actuator should not be located directly underneath the
control valve.
Make sure, in particular, that flange facings (and any flange gaskets) are free from any dirt prior to installation.
Make sure the arrow on the valve body corresponds with the direction of flow in the pipeline.
Note
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.
Caution
Tighten the flange bolts evenly and in a criss-cross pattern in at least three steps. Tighten all flange bolts using
the torques specified in Tables 2 or 3.
Use a torque wrench to ensure that the torque specified is reached, yet not exceeded.

Warning
Since PFA/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.
The associated instructions apply for connecting the actuator unit to the control equipment.
After completing installation, carry out a function check using the signals issued by the control equipment. The valve must
open and close properly corresponding with the control signals. Any function errors that are recognized must be remedied
before commissioning. See also section 7 <Troubleshooting>.
Warning
Control commands that are not carried out correctly may result in personal injury and can damage equipment
installed in the pipeline.

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 points must be observed:
Carefully flush newly installed pipes to remove any foreign material.
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 nameplate).
If a valve leaks, proceed as described in section 7 <Troubleshooting>.
6. Standard operation and maintenance
Due to the fact that PTFE/PFA plastic facings have a tendency to flow, we strongly recommend to check flange bolt
torques as specified in section 4.2 after commissioning and the normal operating temperature has been reached.
Operate the valve/actuator unit over the control equipment signals.
Control valves delivered with the actuator already mounted are precisely set and should not be readjusted.
The shaft is sealed with a PTFE bellows seal 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.
Regular maintenance work on the control valves is not necessary.
Control valves with bellows seal or diaphragm are equipped with a leak-off connection (e.g. 1/4“) between bellows seal /
diaphragm and the external shaft seal which allows you to check whether the bellows seal or diaphragm are leaking.
If a valve leaks, proceed as described in section 7 <Troubleshooting>.
7. Troubleshooting
Observe the safety instructions listed in section 2 on troubleshooting.
Warning
To remove a valve from a pipeline containing dangerous media and to take it out of the plant:
Decontaminate the valves properly first.

Caution:
The permissible tightening torque of the flange bolts is restricted. See table
2 or 3 in section 4.2 <Installation instructions>.
If the medium leaks out at the flanges of the lined valve:
Retighten the flange bolts using the torque specified in Table 2 or 3 in section 4.2
<Installation instructions>. If necessary, the torque may be increased by max. 20 %.
The medium leaks out at the flanges even after tightening the flange bolts:
Unscrew the flange bolts and remove the valve (on doing so, observe the instructions in
section 2.3 <Particular hazards>).
Check the parallel planes of the flanges and, if necessary, correct them. Also check the
facing of all the flanges. If the plastic lining is damaged, replace it together with the
associated flange gasket.
Note 1:
When ordering spare parts,
include all the specifications
listed in the valve
designation. Only use
original parts from Pfeiffer.
Note 2:
If, after removing the valve
from the pipeline, it is found
that the PFA/PTFE lining is
not sufficiently resistant to
the process medium, select
parts made of a suitable
material.

Leak at the shaft seal
If medium leaks out at the leak-off connection:
Remove the valve (observing the instructions in section 2.3 <Particular hazards>),
dismantle the valve and replace the bellows seal or diaphragm. Contact Pfeiffer for
spare parts and necessary instructions.
If with the option “adjustable stuffing box” the medium escapes at the stuffing box:
This version does not have a leak-off connection on the bonnet. The backup stuffing box
is not gas tight from around 2 bar in the delivered state. This is reached by 3 mms of
posset way of the security stuffing box sealed with red varnish.
If the valve leaks at the stuffing box, the bellows is defective.
Caution! All necessary safety measures must be taken to avoid any possible
accidents. Always take into account that you are nearly always dealing with
dangerous medium.
Tighten the stuffing box.
Caution! The valve no longer leaks; however, it should be repaired as
quickly as possible, as there is no primary sealing. The sealing through the
stuffing box should only be for a short period.
Remove the valve (observing the instructions in section 2.3 <Particular hazards>),
dismantle the valve and replace the bellows seal. Contact Pfeiffer for spare parts and
necessary instructions.
Note 1:
When ordering spare parts,
