Safety instructions and safety measures

Intended use
The PFEIFFER butterfly valve BR 10e is manually operated in
combination with a rotary actuator for the regulation of thevolume flow, pressure and temperature of fluid, gaseous orvaporous media.
− The butterfly valve and its drive are designed for precisely
defined conditions (e.g. operating pressure, utilised medium,
temperature).
Therefore the operator must make sure that the butterfly valve
is only used when the conditions of use comply with thedesign criteria defined in the order.
If the operator would like to use the butterfly valve in otherapplications or environments, they must contact PFEIFFER.
− Manual butterfly valves are only intended for use, after
installation in a pipe system, to cut off the media, let it flow
through or regulate it within the permitted pressure andtemperature limits.
− Automated butterfly valves are only intended for use, after
installation in a pipe system and after connecting the drive tothe control, to cut off the media, let it flow through or regulate
it within the permitted pressure and temperature limits.
− The data sheet contains the permissible pressure andtemperature range for these butterfly valves  TB 10e. The
safety regulations that apply to the pipe system in which thevalves are installed and to the control system to which theactuator is connected also apply to the butterfly valves.
This manual only provides safety instructions that are to beobserved additionally for butterfly valves.
There may be additional safety instructions in the manuals forthe actuator assemblies.

Design and principle of operation

VersionThe 10e series butterfly valve has the following properties:− Valve body from EN-JS 1049 (GGG 40.3) with DIN version
or A395 with ANSI version.
− Isostatic lining of the butterfly valve body made of min. 3 mm
thick PTFE.
− Body version as a screw-in butterfly valve (lug type) or
clamping butterfly valve (wafer type).
− Valve disc and butterfly valve shaft made of corrosion-resistant cast steel 1.4313 with PTFE coating.
− Valve disc and butterfly valve shaft one-piece out of 1.4469
with DIN version or A890-A995 5A with ANSI version.
Function and principle of operation

Fail-safe position
Depending on the mounting of the pneumatic rotary actuator, thebutterfly valve has two fail-safe positions that are activated when
the pressure is released as well when the supply air fails:− Butterfly valve with fail-close actuator [FC]:
Upon air failure, the butterfly valve is closed. The butterfly
valve opens when the signal pressure increases, acting
against the force of the springs.
− Butterfly valve with fail-open actuator [FO]:Upon air failure, the butterfly valve is opened. The butterfly
valve closes when the signal pressure increases, acting
against the force of the springs.
Changing the fail-safe position
The fail-safe position of the actuator can be reversed if required,for this purpose see the installation and operating instructions forthe respective pneumatic actuator.

The BR 10e butterfly valves can be flowed through in both directions.

Operating elements and functions

The position of the valve disc (3) determines the flow with the area released opposite of the liner.

The BR 10e butterfly valve can be selected in the following versions:

The valve disc shaft is sealed on both sides by disc spring
preloaded (5) inlay press packings (7 and 16) as well as byo-rings (12, 13 and 14).

− With lever and ratchet

Inlay (6) is inserted to seal between the valve disc (3) and the liner (2).

− With manual gear
− With diaphragm rotary actuator BR 30a− With PFEIFFER rotary actuator BR 31a− With rotary actuators from other manufacturers (for details
see the respective data sheet).

pass. By means of the bypass, the entire plant does not have tobe decommissioned during maintenance and repair work on thebutterfly valve.
Insulation
The butterfly valves can be insulated to reduce the passage ofheat energy.
Observe the notes in Chapter “ 5 Assembly”.
Grip protection
In the case of conditions of use that require a high level of safety(e. g. if the butterfly valve is freely accessible to untrained specialist personnel), PFEIFFER offers a safety guard to prevent therisk of crushing due to moving parts (actuator- and control shaft).
The risk assessment of the plant by the operator will indicate if
the installation of this protective device is required for the safe
operation of the butterfly valve in the plant.

3.3 Attachments
The following accessories are available either individually or in
combinations:− Positioner− Limit switch− Solenoid valves

Preparation of the assembly
To assemble the butterfly valve, all parts must be prepared, e.g.
the parts are carefully cleaned and placed on a soft mat (rubber
mat or other). Keep in mind that plastic parts are almost always
very soft and very delicate, and in particular the sealing surfaces
may not be damaged.
NOTE
Damage due to cold welding of the screws in the body!
PFEIFFER recommends a heavy-duty grease paste (e.g. Gleitmo
805, manufacturer Fuchs) to prevent the cold-welding of thescrews in the bodies.
Ö Do not use this product for butterfly valves with use of oxygen.
Ö A suitable lubricant must be selected for grease-free butterfly
valves, especially for use with oxygen.
Damage to the parts in contact with media due to unsuitablegrease.
Ö When assembling the shaft, liner, valve disc and all otherparts in contact with media, only use water-free grease (e. g.
with halocarbon TM).

Info
The position and arrangement of the individual parts shown inthe drawings must be observed during assembly.

− Supply air regulator/filter− Pressure gauge mounting blocks
Other additional equipment is possible according to specifications on request.

5.2 Preparing for assembly

The work described in this chapter may only be performed by
specialist personnel qualified to perform the corresponding task.

Butterfly valves must be handled, transported and stored withcare, see Chapter “4 Delivery and on-site transport”.

The following instructions apply additionally for butterfly valves.
Observe chapter “4.3 Transporting and lifting the butterfly valve”
for transport to the installation site.

Perform the following steps after receiving the goods:

5.1 Installation conditions

Ö Check the supply for transport damage. Report transport
damage to PFEIFFER and the transport company (see the delivery note).

Operator level
The operator level for the butterfly valve is the front view on all
operating elements of the butterfly valve including the attachments from the perspective of operating personnel.
The plant operator must make sure that operating personnel can
carry out all work after the device is installed safely and can access it easily from the operator level.
Pipe routing
The guidelines applicable on site apply for the installation of butterfly valves in the pipe.
Install the butterfly valve such that there is low vibration and no
mechanical stress. Observe the sections “Installation orientation”
and “Support and mounting” in this chapter.
Install the butterfly valve so there is enough space to replace theactuator and butterfly valve as well as to perform maintenancework.
Installation position
The preferred installation position is with the control shaft horizontal. The actuator should not be located directly below the butterfly valve, if possible.
Ö In the case of deviations from this installation position, contact PFEIFFER.
Support and mounting
The plant manufacturer is responsible for the selection and implementation of a suitable support or mounting for the installed butterfly valve as well as the pipe.
Venting
Vents are screwed into the exhaust air connections of pneumaticand electropneumatic devices to ensure that the generated exhaust air can be released to the outside (protection against overpressure in the device). Furthermore, vents allow the intake of air(protection against underpressure in the device).
Ö Carry out venting on the side that faces away from the operator level.
Ö When connecting the attachments, make sure that they canbe accessed from the operator level safely and easily.

EB 10e_EN
November 2023 edition
Subject to technical changes

Ö Check the scope of supply. Compare the delivered goods
with the delivery note.

Ensure the following conditions prior to assembly:− The butterfly valve is clean.
− The butterfly valve data on the type plate (type, nominal size,
material, nominal pressure and temperature range) matches
the plant conditions (nominal size and nominal pressure of
the pipe, medium temperature, etc.). For details about themarking, see Chapter “2 Markings on the device”.
− Desired or required additional fittings, see Chapter “3.2 Additional fittings”, are installed or prepared as far as necessary
before the assembly of the butterfly valve.

5.3 Assembling the butterfly valve and actuator
PFEIFFER butterfly valves are supplied in working order. In individual cases, the actuator and butterfly valve are delivered separately and must be assembled. The tasks are listed below that arenecessary for assembly and prior to the commissioning of thebutterfly valve.
WARNING
Danger and damage due to retrofitting an actuator unit!
The subsequent fitting of an actuator unit can pose a danger tothe user and cause damage to the pipe system.
Ö The torque, rotation direction, actuation angle and adjustment of the “OPEN” and “CLOSED” end stops must be
adapted to the butterfly valve.
Danger and damage due to use of an electrical actuator!
Ö Make sure that the butterfly valve in the “CLOSED” position isturned off by the signal of the torque switch.
Ö In the “OPEN” position, the butterfly valve must be turned off
by the limit switch.
Ö If shut-off takes place in an intermediate position due to thesignal of the torque switch, this signal should be used in addition for an error message. The fault must be remedied assoon as possible see Chapter “8 Faults”.
Ö For further instructions, see the electrical actuator manual.
Danger and damage due to high external loads on an actuator
unit!
Actuators are not “stepladders”.
Ö Loads may not be applied to the actuators as they can damage or destroy the butterfly valve.

5-1Installation

WARNING
Danger and damage due to heavy actuators!
Actuators that are heavier than the weight of the butterfly valve
can pose a danger to the user and cause damage to the pipe
system.
Ö These actuators must be supported if they generate a bending stress on the butterfly valve due to their size and/or installation situation.

Ö The connection ends of the pipe must align with the butterfly
valve connections and have plane-parallel ends. Connection
flanges that are not plane parallel can damage the PTFE lining during installation.
Ö The connection data for the actuator unit must match the control data. See the type plate(s) on the actuator unit.
Ö Prior to installation, the butterfly valve and the connectedpipe must be carefully cleaned of any contamination, in particular solid foreign matter.
Ö The sealing surfaces on the flange connection and any utilized flange seals must be free of all contamination during installation.
