2. General

These operating instructions apply to KSB offset disc butterfly valves
Design,

manufacturing

and testing of the KSB valves are subject to a
Quality Assurance System according to EN ISO 9001 and to the
European Pressure Equipment Directive 2014/68/EU (PED).

Correct installation and maintenance or repair are mandatory to
ensure trouble free operation of the valves.

The

manufacturer

cannot be made liable for these valves if operating

instructions are not being observed.

ATTENTION

The valves must not be operated beyond the limits

defined in the operating

instructions/contractual

documentation/type
leaflet. Any use beyond the above conditions will lead to overload
which the valves cannot withstand.

3.1. Safety Symbols in these Operating

Instructions

Safety instructions put forth in this instruction manual, the
nonobservance

of

which would involve the

risk of

personal injury,

they

are specially marked with the general hazard symbol:

in accordance with ISO

3864-

B.3.1.

or with the electric voltage warning sign:

Nonobservance

of this warning may lead to personal injury or

property damage, e.g.:

- Injury caused by escaping fluids (cold/hot, toxic, flammable,

corrosive or under pressure)

- Incorrect operation or destruction of the valve.
The descriptions and instructions in this manual refer to the standard

versions but also apply to the related variants.
These operating instructions do not take into consideration:

- Incidents which may occur during installation, operation and

maintenance.

- The local safety regulations. lt is the user’s responsibility to ensure

that these are also observed by the installation staff involved.

For actuated valves, the specified connection parameters and the
installation and maintenance instructions - including the operating
manual for the actuator --- must be observed.

ATTENTION

Handling a valve requires skilled and experienced

personnel.
The

personnel

in

charge

of

operation, maintenance

and

installation

of

this valve must be aware of the

interaction

between the valve and the

plant.
Operator’s errors concerning the valve may have serious

consequences for the entire plant, e.g.:

- fluid may escape

- downtime of the plant/machine

- adverse effect/reduction/increase of the efficiency/function of a

plant/machine.

For further questions or in case of damage to the valve, please

contact

your KSB Sales Office.
For further questions and supplementary orders, especially when

ordering spare parts, please always state the indications of the
marking plate.

The specifications (operating data) of the valves are listed in the
technical documentation & type leaflet of the related valve (see also
section 5).

When returning valves to the manufacturer, please refer to section 4.

3. Safety

This manual contains basic instructions to be complied with during
operation and maintenance. lt is therefore vital for the fitter and the
operator/user

to

read

this

manual before installing/commissioning

the

valve.

Also, this manual must always be available at the site where

the

valve is installed.
lt is

not enough to observe the general instructions listed in the

section
”safety”, the specific safety instructions listed in the other sections
should also be observed.

In accordance with ISO

3864-

B.3.6.

Safety

instructions

the

nonobservance

of which would

involve

hazard
to the valve and jeopardize its operation have been marked with the
word

ATTENTION

lnstructions directly attached to the valve, (e.g. nominal pressure)
must be complied with and maintained in a legible condition.

3.2. Qualification and training of personnel

The personnel for operation, maintenance, Inspection and

installation
must be adequately qualified for the work involved. The personnel
responsibility, competence and supervision must be clearly defined

by

the user. lf the personnel in question is not already in possession of

the
required know-how, appropriate training and instructions must be
provided. lf

deemed necessary, the manufacturer/supplier will

provide
such training and instructions at the user’s request. In addition, the
user is responsible for ensuring that the contents of these operating
instructions are fully understood by the personnel involved.

3.3. Danger or nonobservance of the safety

instructions

Nonobservance

of the safety instructions may lead to personal injury
and danger for both the environment and the valve itself.
Nonobservance

of these safety instructions will also forfeit the user’s
warranty.

Such noncompliance could result in for example :

- failure of essential functions of the valve/plant

- failure of prescribed maintenance and repair practices

- hazard to people by electrical, mechanical or chemical effects

-

hazard to the environment due to leakage of hazardous

substances

3.4. Safety Consciousness

The safety instructions contained in this manual, the applicable
national accident prevention regulations and any of the user’s own
applicable

internal work, operation or safety

instructions

must be fully

complied with.

3.5. Safety Instructions for the

User/Operator

Any

hot

or

cold parts

of

the valve

(e.g.

body

or

handle

or

actuator)

that

could

cause a hazard must

be

protected by the user against

accidental

contact.
Leakage of hazardous substance (e.g. flammable, corrosive, toxic,

hot) must be drained so as to avoid all danger to people or the
environment. All relevant laws must be observed.

Electrical hazards must be effectively prevented. (For details,
please refer to the IEC 364 or equivalent national standard and/or
local utility energy supply regulations).

3.6. Safety lnstructions for Maintenance, Inspection and Installation work

3.6.1. General

The user is responsible for ensuring that all maintenance, inspection and installation work is carried out by authorized, adequately
qualified staff who are thoroughly familiar with this instruction manual. Any work on a valve may only be performed when the
valve is un-pressurized and has cooled down to 60 ° C or has warmed up to 0 ° C .
Any work on actuated valves may only be done after that the actuator has been disconnected from its energy supply.
The procedure described in the operating instructions to shut down the actuator must be observed. Valves in contact with
hazardous media must be decontaminated. Immediately following completion of the work, all safety relevant and protective
devices must be reinstalled and/or re-enabled. Prior to recommissioning, refer to the points listed under section 7 Commissioning.

3.6.2. End of line installation

Use as end of line and downstream dismantling is not allowed.

3.7. Unauthorized Modification and Manufacturing of Spare Parts

The equipment shall not be altered or modified in any way prior to consultation with the manufacturer. Genuine spare parts
and accessories authorized by the manufacturer will ensure operational safety. The manufacturer cannot be held responsible
for damage resulting from the use of non-genuine parts or accessories.

3.8. Inadmissible Modes of Operation

Operational safety and reliability of the valve supplied is only warranted for its designated use as defined in section 2 ”General”
of the operating instructions. The limits stated in the technical documentation must not be exceeded under any circumstances.

3.9. Draining plug

Before unscrew draining plug, pressure in the pipe should be removed.

4. Transport and Interim Storage

4.1. Transport

The valves in the as-supplied condition are ready for operation.

ATTENTION

For transport and storage, the valves must always be maintained in the semi--- closed position and be packed in

cardboard, crate or case with suitable protection (dessicant, thermowelded barrier).

ATTENTION

To prevent damage, do not hang the valve by its handle or actuator. After delivery or prior to installation,

the valve should be checked for damage during transit.

4.2. Interim Storage

The valves must be stored in such a way that correct operation is assured even after prolonged storage.
This comprises: - Storing at 5° from the closed position

- Suitable measures against contamination, frost and corrosion (e.g. by using thermowelded plastic bags with
dessicant, protection caps and plugs onto threaded holes).

5.4. Functioning principle TRIODIS 150
Description

The

valve consists mainly

of a

body (100), operating

shaft

(213),

shaft

(210) and disc (550).

Disc---

shaft connection: The operating shaft (213) is connected to

the disc (550) by grooved pins, splines or taper pins.
Shaft seal area:

MT: realized by elastomer O- Ring (412) fitted into a gasket holder
(559). Fire safety is achieved by a graphite packing

(01-

48) tightened

by the gasket holder (559), screws (901.1) and washers (554).
TBT: realized by elastomer O- Ring (412) fitted into a gasket holder

(559). Fire safety is

achieved

by a

graphite packing (01-

48) tightened

by

the gasket holder (559), screws (901.1) and washers (554). Lip

seal
ring (415.1) tightened by the gasket holder (559), the sealing packing
(01-

48), screws (901.1) and washers (554).

Flow seal area:
MT and TBT: the seat (144) is tightened in the body (100) by a
tightening

flange

(72---

2)

which

is

maintained

by

radial screws (904)

or
axial screws (901).
MT flanged type: the seat (144) is tightened in the body (100) by a
tightening

flange

(72-

2)

which

is

maintained

by

radial screws (904)

or
axial screws (901).
Bonnet seal area:

TBT: It is made by a metallic seal

(41-

2) tightened by the extension

(13-

21), studs (902) and nuts (920).

The compression of the seating disc edge out of the seat is achieved
by triple eccentric kinematics.

The axis of the shafts and disc is offset to valve axis and eccentric to
pipe axis.

Operation: The valves are

quarter---

turn operated manually by
handles or gear box or hydraulic, pneumatic and electric actuators
bolted on the valve top plate (as per ISO 5211 standard).

(550) and a seat (144)

Disc---

shaft connection: The operating shaft (213) is connected to

the disc (550) by a liaison screw or splines or cylindrical keys.
Stem seal area:

TBT: Realized by elastomer O- Ring (412) fitted into a gasket holder
(559). Fire safety is

achieved

by a

graphite packing (01-

48) tightened

by

the gasket holder (559), screws (901.1) and washers (554). Lip

seal
ring (415.1) tightened by the gasket holder (559), the sealing packing
(01-

48), screws (901.1) and washers (554).

Flow seal area:
Tightness between disc (550) and body (100) is done by the seat

6. Installation

6.1. General

ATTENTION

To avoid leakage, deformation or rupture of the body,
the piping should be laid out in such a way that no thrust or bending
forces act on the valve bodies (100) when they are installed and
operational.

ATTENTION

The sealing faces of the flanges must be clean and
undamaged.

It is mandatory to add gaskets between body and piping
flanges. To insert the valve between flanges, pull apart the two pipes
flanges to obtain sufficient clearance between valves flanges and
piping flanges. All holes provided in the flanges must be used for the
flange connection (does not apply for buttweld type valves).

lf construction work is still in progress,

non---

mounted valves

must be

protected

against dust, sand and building

material

etc.(cover

with suitable means).
Do not use gear handwheels as footholds!

Valves and pipes used for high (> 60 ° C) or low (< 0 ° C)
temperatures must either be fitted with a protective insulation, or

there
must be warning signs fitted showing that it is dangerous to touch
these valves.

lf a valve is used as end-valve in a pipe, this valve should be
protected against unauthorized or unintentional opening to prevent
personal injury or damage to property.

To guarantee a good operation of the valves at temperatures
< 0 ° C it is

necessary to eliminate all the water (steam or liquid)

inside

the piping to avoid freezing at the seat gasket or lower shaft level.

6.2. Installation conditions

6.2.1. Recommended minimum distances between the

position of the valve and of the

T---

piece or elbow.

(144). Tightness between seat (144) and disc (550) is done by a
static gasket (400).

Dynamic

seat (144) and static gasket (400) are

maintained

on disc by a tightening flange

(72-

3) and screw (901.2).

The contact pressure between seat and body is guaranteed by triple
offset cinematic and torque of actuator.

Bonnet seal area:
It is made by an extended graphite seal

(41---

21) tightened by

the extension

(13-

21), studs (902) and nuts (920).

Operation: The valves are

quarter---

turn operated manually by gear
box, hydraulic, pneumatic and electric actuators bolted on the valve
top plate (as per ISO 5211 standard).

Also valid for valve placed at pump discharge

6.2.4. Bolting

Length of bolting are defined in Type series booklet. KSB
recommends :

 to follow this length in order to maximize threaded

length.

 For A2 bolts (shaft location), to apply an adapted

tightening torque as a function of state of art
(threading length, material of the bolt, etc …)

15

6.3. Handling

Handling means may be necessary to install large sizes
valves.

Handle only when parts are at ambient temperature

Use only lifting rings delivered by KSB (lifting lugs

paints according to DIN 580 not allowed)
They must be used as shown.
BWSE
Horizontal Vertical

T7

T4

6.4. Recommendations for installation

The lug and flanged valves have to be inserted lightly between
flanges with flange gaskets.

Before assembly

- Verify that the cone on body and the seat are free of solid

particles

like chips, packing material, etc...

- Verify that pipeline flanges are located on the same centerline
and are parallel.

- Verify that dimensions of gaskets flange are compatible with
the dimensions mentioned in the table 6.2.3.

- Verify that nothing hinders the complete moving of the disc
during opening or closing.

- Pull apart the pipeline flanges to allow valve and gaskets

insertion.

During assembly

- Place the disc in closed position.

-

Position the valve above the pipe and place gasket in contact of

each flat face (you can fix them with a spot of glue).

- Insert valve and gaskets between pipe flanges and center
using several tie--- rods.

- Screw up progressively the nuts until metal complete tightness is
achieved between

the valve body, the pipeline flanges and

gaskets. Note: Respect maximum torque (See paragraph 6.2.4).

- Operate the valve several times to ensure that there is no valve
disc obstruction.

- During transport, the valve may have been subjected to
important temperature differences or the vibrations making it
necessary to retighten the assembly. Before performing this
operation, please read the maintenance manual.

6.5. Actuated valves

Actuator bumpers are adjust in KSB factory.

Do not modify the adjusting to preserve gasket.

Electrical cables may only be connected by qualified

personnel.

The applicable electrical regulations (e.g. IEC and national
standards), also for equipment in hazardous locations, must be
observed. All electrical equipment such as actuator, switchboard,
magnetic valve drive, limit switch etc. must be installed in flood
proof dry

locations. Voltage

and frequency must match the valves

stated on the identity plate.

The seat (144) and the disc edge shall be protected against
the metallic projections resulting from welding or grinding.

If the valve is used with a non irreversible actuator, it is necessary
to maintain alimentation of actuator to guaranty tightness
performance.

7. Commissioning/Decommissioning

7.1. Commissioning

7.1.1. General

Prior to commissioning the valve, the pressure, temperature
and material data stated on the valve should be compared to the
actual operating conditions in the piping system to check whether
the valve can withstand the loads occurring in the system.

Possible pressure surges (water hammer) must not be

exceed
the highest admissible pressure. Adequate precautions should be
taken. In new pipe systems and especially after repair work, the
system should be flushed with the valves fully open to remove
solids, e.g. weld beads, which may damage the seats.

7.1.2. Operation

The

position

of the disc is

indicated

by the

pointer

of the

actuator

or
by handle lever. The valves are closed by turning in the clockwise
direction (top view) and opened in the counterclockwise direction.

7.1.3. Functional Check

The following functions should be checked before commissioning,
the shut-off-function of the valves should be checked by repeated
opening and closing.

7.1.4. Actuated valves

Adjustable end stops and torque limiter of actuators have been
adjusted in factory.

7.2. Decommissioning

During extended shutdown periods, liquids liable to change their
condition

due to polymerization, crystallization, solidification etc.
must be drained from the piping system. If necessary, the piping
system should be flushed with the valves fully open.

8. Maintenance/Repair

8.1. Safety Instructions

Maintenance and repair work may only be carried out by skilled
and qualified personnel.

For all maintenance and repair work, the safety instructions listed
below and also the general notes in section 2 must be observed.
Always use suitable spare parts and tools, even in case of
emergency, otherwise correct operation of the valves cannot be
assured.

8.2. Valve removal from piping and
actuator disconnecting

Identify the valve by identity plate.

Please check what is the relevant spare kit. Place the disc

in closing position

The entire valve must be unpressurized and must have
cooled down sufficiently so that the temperature of the medium is
lower than 60 ° C, to prevent scalding or warmed so that the
temperature is higher than 0 ° C.

Opening pressurized valves will cause danger to life and
limb! lf toxic or highly flammable substances or liquids whose
residues may cause corrosion by interaction with the air humidity
were handled by the valve, then the valve should be drained and
flushed or vented. lf necessary, wear safety clothing and a face
guard/mask. Depending on the installation position, any liquid
remaining in the valve may have to be removed.

Prior to possible transport, the valves must be flushed and drained
carefully. lf you have any questions please contact your KSB
Sales Office.

lf actuators powered by an external source of energy
(electric, pneumatic, hydraulic) need to be removed from the
valves or dismantled, the energy supply must be shut down prior
to starting any repair work.

Remove the valve from the piping with its actuator. Identify
the mounting position of the actuator

Disconnect the actuator and take care of all bolting parts.

8.3. Spares

Use the relevant spare parts included in the kits. Please refer to
the manual maintenance.

All constitutive parts of kit and flange gaskets must be replaced.

During the mounting /dismantling of the valve, the
operations must be respected step by step to prevent injuries and
material damages.

During the tests, closing and opening valves, care must be taken
that no operator interferes with the disc travel.

8.4. Valve disassembly and

re---

assembly

See manual of maintenance reference:

Manual of maintenance Reference
Maintenance leaflet TRIODIS 150 8460.81/5- 10
Maintenance leaflet TRIODIS 8465.81/1- 10

300- 600- 900

8.5. Draining plug

Before unscrew draining plug, pressure in the pipe should be
removed. In order to prevent unwished lost of screw, apply glue at
each reassembly.
