1 GENERAL
1.1 Valve description
The E2 ceramic ball valve is a flangeless (wafer type),
and E6 is a single flange (lug type) reduced-bore valve
specially designed for control of erosive media.
The body and shaft are metal, while the trim is ceramic.
There are no separate ball seats; instead, the seating
surfaces are directly ground into the ceramic bushings.
The insert retaining ceramic parts is attached to the
body with threaded joint. The flow medium comes into
contact with the metallic valve body. Note this when the
valve is used for aggressive media.
Rotation transmission between shaft and ball takes
place through a slot head. Axial bearings are located
outside the valve, under the actuator mounting piece.
The valve is usually equipped with an actuator. (For
details, see type-specific instructions.
1.2 Valve markings
The markings stamped on the body indicate the
❑body material
❑nominal size
❑pressure rating
The valve also has an identification plate, the type of
which depends upon the size of the valve. See Figure 1.
The different sections of the identification plate give the
following informations:
1. body material
2. trim material
3. shaft material
4. seat material
5. highest operating temperature
6. lowest operating temperature
7. maximum shut-off pressure differential
8. type designation
9. number in manufacturer’s list

1.6 Safety precautions
2 TRANSPORTATION, RECEPTION
AND STORAGE
Valves are delivered in the usual Metso packaging,
unless otherwise agreed with the customer.
Make sure that the valve and any possible accessories
have not been damaged during transport.
Do not remove the bore protectors before installation.
Store the valve with care, preferably indoors and in a
dry environment.
Take the valve to the installation site only just before
installation.
3 INSTALLATION AND USE
Remove the bore protectors and check that the valve is
clean. Also ensure that the pipeline is clean.
The pipeline must be firmly supported so that the valve
is not subjected to additional strain.
The valves can be installed between the following
flanges:
❑EN PN 10, 16, 25, 40
❑ASME 150, 300
❑ISO 7005 PN 20, PN 50
❑JIS 10 K, 16 K, 20 K, 30 K
In some valve sizes the body of the valve has thread fil-
lets for the two flange screws located closest to the shaft.
Size NPS 8 / DN 200 has thread fillets for all flange
screws. See Figure 4 and Tables 1 to 3. All other dimen-
sions are shown in Section 9.
The valve is tight in both directions and may be
installed in any position. It must not, however, be
installed in such a way that the actuator is below the
valve (see Figure 5).
The actuator must not come into contact with the pipe-
line, as vibrations in the pipeline might damage the
actuator and its performance.
CAUTION:
Due to the nature of ceramic material used in valve inter-
nals, the valve might cause an ignition of explosive gas
mixtures. Valve internals, when operating against each
other may cause sufficient heat to ignite the gaseous mix-
ture inside the valve. Therefore the safe use of the valve
must be assessed when used in potentially explosive and
flammable applications. According to the Hazard Analysis
the valve is not creating an ignition risk to its environment
outside the valve. For further information, please contact
Metso’s Automation business.
CAUTION:
Do not exceed the valve performance limitations!
Exceeding the limitations marked on the valve body may
cause damage and lead to uncontrolled pressure
release.
Damage or personal injury may result.
CAUTION:
Do not dismantle the valve or remove it from the
pipeline if the valve is pressurized!
Damage or personal injury may result. Dismantling a
pressurized valve will cause uncontrolled pressure
release. Always isolate the required part of the pipeline,
release the pressure from the valve and remove the
medium before dismantling the valve. Be aware of the
medium type. Protect people and equipment in the area
from any harmful or poisonous medium. If the valve is
actuator operated, close and detach the actuator pres-
sure supply pipeline.
CAUTION:
Be aware of the ball cutting movement!
When the valve is actuated, the ball functions as a cut-
ting device.
Do not stick your hand or other body parts into the open
flow port. Prevent foreign objects from being left inside
the pipeline. If the valve is actuator operated, close and
detach the actuator pressure supply pipeline.
CAUTION:
Be aware of noise emission!
Depending on the application the valve may cause noise
emission during use. The noise level can be measured
with equipment designed for this purpose or by using
the Metso Nelprof software. Pay attention to work envi-
ronment legislation concerning noise emission.
CAUTION:
Be aware of extreme temperatures!
During use the valve body may be very cold or very
hot. If extreme temperatures occur, protect people
from frost injuries or burns.
NOTE:
Do not drop, knock or hit the valve!
Internal parts of the valve are made of ceramic material.
Although the material is robust, it will not tolerate impact
as metals do.
NOTE:
Media which may solidify should not be allowed to stand
in the ball valve. Wash such media from the valve using a
suitable arrangement. Cycle a valve few times when
washing.
Fig. 3 Storage of the valve
NOTE:
Ceramic valves must be handled with particular care.

To facilitate easy maintenance, the actuator should be
installed in such a way that there is plenty of room for
removing it.
The screws, nuts and washers used should be equiva-
lent to the fastenings used elsewhere in the pipeline.
Pay particular attention when centring the flange gasket.
The inside diameter of the gasket should be acc. to the
nominal size of the valve, i.e. the gasket covers the insert (6)
and the rim of the ceramic bushing (3).
The pipeline should be flushed carefully before use.
The valve should be kept entirely open during flushing.
3.1 Valve insulation
If necessary, the valve may be insulated. Insulation
must not continue above the upper level of the valve
body, see Figure 6.
4 MAINTENANCE
4.1 General
The valve does not require regular maintenance. Its oper-
ation should, however, be checked at regular intervals.
The end use may carry out the following maintenance
tasks himself.

4.2.1 Disassembly
1. Detach the air supply conduit from the actuator. Also
detach any cables preventing the removal of the actuator.
2. Remove the actuator from the bracket (5) by
unscrewing the fixing screws. Pull the actuator from
the shaft (4). Detaching the actuator is described in
more detail in Section 4.7.1.
3. Detach the key (20) from the shaft.
4. Detach the bracket (5) from the body (1) by opening
the screws (13) M12 or M16.
5. Detach the bearing (8), the axial bearing (7) and the
lock ring (19).
6. Loosen the strain ring (9) with a special tool, see
Table 4.
7. Pull the shaft (4), and lift it and gland bushing (10)
and parts (11, 12, 17) out of the valve body.
8. Pull the gland bushing off the shaft while rotating.
Now the gland packing may be disassembled.
9. Remove the gasket (16) between the gland bushing
and the body from the valve body.
4.2.2 Replacing parts
The gland packing set includes the V-ring set (11) and
the spring (12). Replace both parts at the same time.
The O-ring (17) should be replaced if it is damaged.
The main purpose of the O-ring is to protect the shaft
from erosive media, such as sludge, and it therefore
does not need to be changed regularly.
4.2.3 Assembly
1. Apply silicon grease to the O-ring (17) and install it
into the gland bushing (10) cavity.
2. Slip the gland bushing (10) onto the shaft (4).
3. Install the spring (12) into the bottom of the gland
bushing (10). Before installation, the spiral should
be completely compressed once, for example in a
vice. This will make installation of the strain ring eas-
ier, since the working height of the spiral is roughly
0.6 x the free height of the spring.
4. Once the spiral is in place, slip the sheet ring (15)
into position. After this, install the V-ring (11) onto the
shaft, one by one.
The order from bottom to top of the different rings is as
follows:
❑base ring
❑angle rings
❑saddle ring
5. Place the gasket (16) into the valve body.
6. Insert the shaft together with the gland bushing
back into the valve body.
7. The shaft joint on the ball has been shaped in such
a way that the shaft only fits seat when it is in the
correct position. Check the direction of the bore by
observing the indicator line at the top of the shaft,
and take the position of the keyway into account
when you install the actuator.
8. Lubricate the thread of the strain ring with, for exam-
ple, Molykote. Then fasten the strain ring (9). When
correctly fastened, the ring shoulder must be at least
on a level with the body, or 0.1 mm below it. The tight-
ening torques are given in Table 4. The shoulder of the
strain ring must not remain above the surface level of
the body.
9. Make sure that the bracket (5) is not carrying the
weight of the valve because this would have an
immediate effect on the bearing clearance.
10.Install the lock ring (19), the axial bearing (7) and
the bearing (8) onto the shaft.
11.Attach the bracket to the valve body. While fastening
the screws, make sure that the hole in the bracket is
properly centered in relation to the shaft. For the
correct tightening torques, see Table 5.
12.Install the actuator. See Section 4.7.2.
CAUTION:
Do not detach or disassemble a pressurized valve!
This warning also applies to individual compo-
nents (13).
NOTE:
Replace the gasket (16) between the gland bushing (10)
and the body (1) whenever the strain ring has been loos-
ened. Leakage of the V-ring set (11) and leakage of the
gasket (16) may cause similar symptoms.
NOTE:
Make sure you do not damage the O-ring with the shaft
keyway and the shaft shoulder.
NOTE:
Make sure you do not damage the gland packing rings
with the shaft keyway or shaft shoulder.

4.3 Changing the gland packing,
H-construction
The part numbers in this section refer to the diagram
and part list in Section 8.2 .
1. Unfasten the nuts (24) of the gland (22) and lift up
the gland.
2. Remove the old packing rings (11) by using, for
example, a sharp pricker.
3. Install the new packing rings.
4. Place the nuts on the studs and tighten the gland
packings while the valve is not pressurized, see
Table 6.
5. Retighten if necessary.
4.4 Changing the gasket of the gland
packing
In an H-construction valve, changing the gland packing
does not require unfastening the strain ring, and this
does not entail changing the gasket (16).
When the gasket (16) needs to be changed, this can be done
by following the same instructions that were given for the A-
construction. Note that there is no O-ring in the H-construction.
4.5 Changing the bearing,
A-construction and H-construction
1. Detach the actuator from the bracket, see Section
4.7.1.
2. Detach the bracket (5) from the valve body (1) by
unscrewing fixing screws (13) M12 or M16 and
detach the key from the shaft.
3. Detach and change the bearing (8).
4. Attach the bracket to the valve, see Table 5.
5. Install the actuator, see Section 4.7.2.
4.6 Changing the ceramic parts
Changing the ceramic parts, ball (2) and bushings (3)
requires special tools. It is highly recommended that
this work is done by the Metso service organisation.
4.6.1 Disassembly
1. Detach the actuator from the valve, see Section
4.7.1.
2. Detach the key (20), fixing screws (13), bracket (5),
axial bearing (7), bearing (8) and lock ring (19).
3. Fasten the valve firmly into a vice the insert (6) point-
ing upwards.
4. Fasten the special tool, Table 7, to the insert and
turn it open without removing it.
5. Remove the strain ring (9) with a special tool,
Table 4. See also Sections 4.2.1, 4.3 and 4.4.
6. Pull the shaft (4) with gland bushing (10) out of the
body.
7. Remove the insert (6) and detach the ceramic parts,
bushing (3), ball (2) and bushing (3), from the body.
8. Remove the gasket (25) between the insert and
body (8"/DN 200 only).
4.6.2 Assembly
1. Apply Molykote 312R lubricant to the threads of the
insert (6).
2. Turn the insert into metal-to-metal contact with the
body (without ceramic parts) and draw a mark with
a felt tip pen to the body and insert seam.
3. Remove the insert.
4. Install the sheet rings (14) on the bushings (3).
5. Place the ball (2) between the bushings (3).
6. Push the ceramic parts as a package into the body.
Please note the position of the shaft slot.
7. Install the gasket (25) on the body (1) (8"/DN 200 only).
8. Turn the insert (6) lightly into the body.
9. Push a assembly guide tool, Table 7, through the
gland bore into the slot of the ball. Make sure that
the tool is properly engaged with the ball. The tool
will keep the bushings (3) in place during the tight-
ening of the insert (6).
10.Fasten the valve firmly into a vice the insert (6) pointing
upwards and tighten the insert evenly using a special
tool 1...2 mm past the mark made earlier. See Table 8.

11.Remove the assembly guide tool from the gland
bore and mount the shaft (4). See Sections 4.2.3,
4.3 and 4.4 for details of gland packing assembly.
Tighten the strain ring (9) according to Table 4.
4.7 Detaching and installing the actuator
4.7.1 Detaching from the valve
1. Detach the air supply tube from the actuator. Also detach
any cables preventing the removal of the actuator.
2. Detach the actuator from the bracket (5) by
unscrewing the fixing screws.
3. Pull the actuator off the shaft by using a special extrac-
tion tool, Figure 8. Prevent the shaft from pressing the
ceramic ball when removing, e.g. by gripping the shaft
with self-locking pliers (don’t damage the shaft) .
4.7.2 Installation onto the valve
Clean the shaft boring of the actuator. Lubricate the
shaft boring and the valve shaft with, for example,
Cortec® VCI 369 anticorrosive agent.
The installation position of the actuator is determined as
follows:
❑The B1C-actuator is installed in such a way that
the piston is in the extreme outward position
when the valve is closed.
❑The B1J/B1JA-actuator is installed in one of two
positions, depending on the function required
(spring opens/spring closes).
❑The actuator mounted the valve before is
installed in the same position.
❑Carefully insert the actuator over the valve shaft
and make sure the shaft does not press the
ceramic ball, use e.g. self-locking pliers (don’t
damage the shaft).
❑Make sure that the actuator is straight in relation
to the valve.
❑Insert and tighten the fixing screws.
❑Check to see that the limiter screws of the open
and closed position are properly adjusted.
More information concerning the actuator is available in
the installation, operation and maintenance instructions
given for the model in question.

NOTE:
Make a note of the mutual position of the valve and the
actuator. This will enable you to keep the operating direc-
tion unchanged during reassembly. Also make a note of
the position of the actuator (valve open/closed).
Fig. 8 Removal of the actuator with an extractor
NOTE:
Do not strike at the actuator during installation because
this might damage the ceramic parts.
NOTE:
The actuator has an arrow indicating the flow direction.
Make sure that this arrow is in the correct position in relation
to the bore.
NOTE:
The position of the ball is indicated by means of a groove at
the top of the shaft, which shows the direction of the bore.
