1.1Scope of the manual
This manual provides essential information on R series Vport segment valves, i.e. RA, RE and RE1-series valves. Actuators and other accessories are only discussed briefly. Refer
to the individual manuals for further information on their
installation, operation and maintenance.
NOTE:
Selection and use of the valve in a specific application
requires close consideration of detailed aspects. Due to
the nature of the product, this manual cannot cover all the
individual situations that may occur when the valve is
used.
If you are uncertain about use of the valve or its suitability
for your intended purpose, please contact Metso Flow
Control business for more information.
For valves in oxygen service, please see also the separate
installation, maintenance and operating instructions for
oxygen service (see Metso document id: 10O270EN.pdf).

1.2Valve construction
RA, RE and RE1-series valves are V-port segment valves
installed between flanges. RE series valves are flanged Vport segment valves. The body is in one part; the shaft and
the segment are separate. Shaft blow-out is prevented by
plates mounted against the shaft shoulder. See Figs. 1 and 2.
The valve is either soft or metal seated. Tightness derives
from the spring force pressing the seat against the segment.
The structure of the valve supplied may vary, depending on
the customer’s requirements. The detailed structure is
revealed by the type code shown on the valve identification
plate. The type code is explained in Section 15.
The valve is designed for both control and shut-off applications.
1.3Valve markings
Body markings are cast on the body. The valve also has an
identification plate attached to it, see Fig. 3.

1.7Recycling and disposal
Most valve parts can be recycled if sorted according to
material. Most parts have material marking. A material list is
supplied with the valve. In addition, separate recycling and
disposal instructions are available from the manufacturer. A
valve can also be returned to the manufacturer for recycling
and disposal against a fee.

CAUTION:
Do not exceed the valve performance limitations!
Exceeding the limitations marked on the valve 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 while the valve is pressurized!
Dismantling or removing a pressurized valve will result in
uncontrolled pressure release. Always isolate the relevant
part of the pipeline, release the pressure from the valve
and remove the medium before dismantling the valve.
Be aware of the type of medium involved. Protect yourself
and the environment from any harmful or poisonous substances. Make sure that no medium can enter the pipeline
during valve maintenance.
Failure to do this may result in damage or personal injury.
CAUTION:
Beware of the segment movement!
Keep hands, other parts of the body, tools and other
objects out of the open flow port. Leave no foreign
objects inside the pipeline. When the valve is actuated,
the segment functions as a cutting device. The segment
position may also change when the valve is moved. Close
and detach the actuator pressure supply pipeline for valve
maintenance. Failure to do this may result in damage or
personal injury.

1.5Valve approvals
The valve meets the Fire-safe requirements of BS6755/API
607 Edition 3.
1.6CE marking
The valve meets the requirements of the European Directive 2014/68/EU relating to pressure equipment, and has
been marke
d according to the Directive.
CAUTION:
Protect yourself from noise!
The valve may produce noise in the pipeline. The noise
level depends on the application. It can be measured or
calculated using the Metso Nelprof software. Observe the
relevant work environment regulations on noise emission.
CAUTION:
Beware of a very cold or hot valve!
The valve body may be very cold or very hot during use.
Protect yourself against cold injuries or burns.
CAUTION:
When handling the valve or the valve package, take its
weight into account!
Never lift the valve or valve package by the actuator, positioner, limit switch or their piping.
Place the lifting ropes securely around the valve body (see
Fig. 13). Damage or personal injury may result from falling
parts.

2TRANSPORTATION, RECEPTION AND
STORAGE
Check the valve and the accompanying devices for any
damage that may have occurred during transport.
Store the valve carefully before installation, preferably
indoors in a dry place.
Fig. 14Installing the valve into pipeline
Servicing is facilitated if the valve needs no support. If necessary, you can support the valve by the body, using regular pipe
clamps and supports. Do not fasten supports to the flange
bolting or the actuator, see Fig. 15.
Fig. 13Lifting the valve
Do not take the valve to the intended location and do not
remove the flow port protectors until the valve is installed.
The valve is delivered in the closed position. A valve
equipped with a spring-return actuator is delivered in the
position determined by the spring.
3INSTALLATION AND COMMISSIONING
3.1General
Remove the flow port protectors and check that the valve is
clean inside.
CAUTION:
When handling the valve or the valve package, take its
weight into account!
3.2Installing in the pipeline
Flush or blow the pipeline carefully before installing the
valve. Foreign particles, such as sand or pieces of welding
electrode, will damage the segment sealing surface and
seats.
The valve has an arrow indicating the flow direction. Install
the valve in the pipeline so that the flow direction of the
pipe corresponds to that marked on the valve. The mounting position does not place restrictions on operation of the
valve, actuator or positioner. You should, however, avoid
installing the valve so that the shaft points downwards
because impurities travelling in the pipeline may then enter
the body cavity and damage the gland packing. See Fig. 14.
The RA and RE1 valves should be applicable to the pipe
flanges, see the table in 11.19.
Choose flange gaskets according to the operating conditions.
Do not attempt to correct pipeline misalignment by means
of flange bolting.
Stress caused in the valve by pipeline vibration can be
reduced by supporting the pipeline properly. Reduced
vibration also helps ensure correct functioning of the positioner.
Fig. 15Supporting the valve
3.3Actuator
NOTE:
When installing the actuator, make sure that the valveactuator combination functions properly. Detailed information on actuator installation is given in Section 6 or in
separate actuator instructions.
The valve closed and open positions are indicated by a
groove at the end of the valve shaft. The groove shows the
position of the segment with respect to the flow port, see
Fig. 16.
Fig. 16Closed and open positions
If possible, install the valve so that the actuator can be disconnected without removing the valve from the piping.

The actuator must not touch the pipeline, because pipeline
vibration may damage it or interfere with its operation.
In some cases, for instance when a large-size actuator is
used or when the pipeline vibrates heavily, supporting the
actuator is recommended. Contact Metso Flow Control
business for further information.
3.4Commissioning
Ensure that no dirt or foreign objects are left inside the
valve or pipeline. Flush the pipeline carefully. Keep the
valve entirely open during flushing.
Check all joints, pipings and cables.
Check that the actuator, positioner and limit switches are
correctly adjusted. Refer to their installation, operation and
service manuals.
4MAINTENANCE
4.1Maintenance general
CAUTION:
Observe the safety precautions mentioned in Section
1.8 before maintenance!
NOTE:
For safety reasons, replace pressure retaining bolting if the
threads are damaged, have been heated, stretched or corroded.
4.2Replacing the gland packing
CAUTION:
Do not dismantle the valve or remove it from the pipeline while the valve is pressurized!
4.2.1RA series
In gland packing, V-ring set (20), tightness is ensured by
pressure caused by the wave spring (32). See Fig. 17.
The gland packing must be replaced when leakage occurs
through the gland (9).
CAUTION:
When handling the valve or the valve package as a
whole, bear in mind the weight of the valve or the
entire package.
Although Metso’s Neles valves are designed to work under
severe conditions, proper preventative maintenance can
significantly help to prevent unplanned downtime and in
real terms reduce the total cost of ownership. Metso recommends inspecting the valves at least every five (5) years.
The inspection and maintenance interval depends on the
actual application and process condition.
The inspection and maintenance intervals can be specified
together with your local Metso experts. During this periodic
inspection the parts detailed in the Spare Part Set should
be replaced.
Time in storage should be included in the inspection interval.
Maintenance can be performed as presented below. For
maintenance assistance, please contact your local Metso
office. The part numbers in the text refer to the exploded
view and to the parts list in Section 10, unless otherwise
stated.
NOTE:
When sending goods to the manufacturer for repair, do
not disassemble them. Clean the valve carefully and flush
the valve internals. For safety reasons, inform the manufacturer of the type of medium used in the valve (include
material safety datasheets (MSDS)).
NOTE:
In order to ensure safe and effective operation, always use
original spare parts to make sure that the valve functions
as intended.

Remove the packing rings (20) from around the shaft
using a knife or some other pointed instrument
without scratching the surfaces.
Clean the packing ring counterbore.
Place the new packing rings (20) over the shaft (11).
The gland follower may be used for pushing the
rings into the counterbore. Do not damage packing
rings in the shaft keyway. See Fig. 18.
Screw down the removed stud.
Deform the packing rings first by tightening the
gland nuts (25) without disc springs to the torque Tt,
see the value from Table 3.
Remove the gland nuts and one stud. Mount the
retaining plates (30) with the text UPSIDE on top and
the removed stud and place the disc spring sets (32)
on the gland studs. Tighten the nuts (25) so that the
disc springs are compressed to the height Hc, see
Table 3. Lock the nuts with locking compound e.g.
Loctite 221. See Fig. 18.
Check leakage when the valve is pressurized.
CAUTION:
For safety reasons the retainer plates MUST always be
installed according to the above instructions.
CAUTION:
When handling the valve or the valve package, take its
weight into account!
NOTE:
Before dismantling, carefully observe the position of the
valve in relation to the actuator and positioner/limit
switch so as to make sure that the package can be properly re-assembled.
It is generally most convenient to detach the actuator and
its auxiliary devices before removing the valve from the
pipeline. If the valve package is small or if it is difficult to
access, it may be more practical to remove the entire package at the same time.
See Section 6 for details of detaching actuators.
4.4Removing the valve from the pipeline
CAUTION:
Do not dismantle the valve or remove it from the pipeline while the valve is pressurized!
Make sure that the pipeline is not pressurized and
that it is empty. Also make sure that no medium is
led into the pipeline while the valve is being
removed or after it has been removed.
Place the hoisting ropes carefully, unscrew the pipe
flange bolts and lift the valve from the pipeline using
the ropes. Note the correct lifting method. See also

cone-shaped bushing, which is tightened firmly with a tightening screw (I) around the valve shaft.
Mount the bushing and the tightening screw from
the mounting interface side of the actuator, according to Fig. 38. Insert cylindrical pins (III) in the bushing slots, these must be directed into the
corresponding slots in the actuator during tightening. Before the installation of the bushing and the
tightening screw, remove impurities such as old
threadlocking material from the threads of the tightening screw, and apply Loctite 225 or similar threadlock carefully to the threads, as shown in Fig. 38. Turn
the tightening screw from inside the actuator shaft
using a suitable hex key, Fig. 39.

5TESTING THE VALVE
CAUTION:
Pressure testing should be carried out using equipment
conforming to the correct pressure class!
We recommend that the valve body be pressure tested
after the valve has been assembled.
The pressure test should be carried out in accordance with an
applicable standard using the pressure rating required by the
pressure class or flange bore of the valve. The valve must be in
the open position during the test.
If you also want to test the tightness of the closure member,
contact the manufacturer.

Prior to installation, the correct keyway position of the
valve has to be checked. The bushing has four keyways,
two of which are intended for valves with DIN key and
two for valve shafts with ANSI key. The ANSI keyway is
located in the middle of the half bushing, and the DIN
keyway is located in the split between the bushing
halves. Fig. 40 shows the keyway position when the
actuator is in a closed position.
Fig. 40Keyway positions on the actuator
The open or closed positions of the actuator can be
identified either by using compressed air, see Fig. 41,
or by checking the position of the pointer at the end
of the drive shaft. The actuator is closed if the pointer
on the coupling plate is transverse to the direction of
the actuator’s main shaft.

The drive shaft will automatically find its correct
position if the installation tool H061904 (see Fig. 39)
is used. The installation tool is attached instead of
the coupling plate using M4 screws with the drive
shaft in lower position (before the valve is installed).
Tighten the nut of the tool in such a way that the
tool pulls the drive shaft to the uppermost position.
The position may be checked from the side of the
tool.
Install the actuator on the valve and attach the valve
mounting screws loosely by hand. Then tighten the
tightening screw (I) according to Table 4. The
required torque is also marked on a plate close to the
drive shaft on the actuator housing. The installation
tool is removed, and the coupling plate is reattached. Finally, tighten the valve mounting screws.
Check the axial position of the drive shaft. The shaft
position may not be at the upper or lower position X
given in Table 4, or close to those values. Remount
the actuator if the position is not correct.
The valve may malfunction if the tightening of the
connection has been carried out improperly.
Finally, the extreme positions of the valve are adjusted
with the stop screws at the ends of the actuator. The
location of the screws for adjusting the Close and
Open positions of the valve are marked with letters on
the ends of the actuator housing, see Fig. 41.

the drive shaft. Check, before the screw is tightened,
that the drive shaft is in the upper position of its axial
movement, which is its normal position (the mounting position shown in Fig. 39). Checking is important,
as the actuator shaft drops down slightly when the
screw is tightened. The drive shaft axial movement
can be observed and measured before attachment to
a valve. The actuator drive shaft is in the upper position when its upper surface conforms to Table 4, see
also Fig. 39.
6.3Detaching EC and EJ actuators
The actuator is detached in the same way that it is attached,
but the order is reversed.
The actuator must always be depressurized and the air supply pipes removed before detaching the actuator.
First detach the positioner, or any other accessory,
from the actuator, and detach the coupling plate
from the drive shaft. Next, the bushing is loosened
by turning the tightening screw counter-clockwise.
The tightening screw also acts as an extractor. It is
highly recommended to use a suitable bushing from
the tool set H061544 between the tightening screw
(I) and drive shaft. The bushing dimensions are given
in Table 5.
Detach the actuator finally from the valve after the
screws that attach the actuator to the valve have
been removed.
Observe the respective positions between the actua-
tor and valve and also between the key and keyway
before removal. Attaching the actuator back is then
easier.

screw
6.4Installing B1C actuators
CAUTION:
Beware of the segment movement!
Fig. 43Open and closed positions of a B1 actuator
Drive the actuator piston to the extreme outward
position and turn the valve into the closed position,
see Fig. 43.
Clean the shaft bore and file off any burrs. Lubricate
the shaft bore.
If a coupling is needed between the actuator shaft
bore and the valve shaft, lubricate the coupling and
install it in the actuator.
Fasten the bracket loosely to the valve using lubri-
cated screws.
Push the actuator carefully onto the valve shaft.
Avoid forcing it, since this may damage the segment
and seat. We recommend mounting the actuator so
that the cylinder is pointing upwards.
Align the actuator as accurately as possible using the
valve as a guide. Lubricate the mounting screws.
Install the washers and tighten all screws, see
Tab le 4.
Adjust the segment open and closed positions (lim-
its to piston movement) by means of the actuator
stop screws, see Fig. 43. The correct opening angle is
90°, for the R2_S valve 70°. The accurate position can
be seen in the flow port. Check that the yellow arrow
indicates the position of the segment.
Keep your fingers out of the flow port!
There is no need to adjust the stop screw if the actuator is
re-installed in the same valve. Drive the actuator piston to
the housing end (open position).Turn the actuator by hand
until the valve is in the open position (unless it is already
open). Fasten the actuator in this position. The actuator
may be installed in another position with respect to the
valve by selecting another keyway in the actuator, see
Fig. 44.
Fig. 44Changing the actuator position
Check the tightness of the stop screw at the end of
the cylinder during cylinder operation. The threads
must be sealed using an appropriate non-hardening
sealant, e.g. Loctite 225.
Check that the actuator is functioning correctly.
Check the segment flow bore position and the actuator movement relative to the valve (clockwise:
close, counterclockwise: open) after installing the
actuator. The valve should be closed when the piston is in the extreme outward position.
Check that the yellow arrow indicates the position of
the segment. If necessary, change the position of the
arrow.
6.5Installing B1J actuators
Spring-return actuators are used in applications where
valve opening or closing movement is needed in case the
air supply is interrupted. The B1J type is used for spring-toclose operation; the spring pushes the piston towards the
cylinder end, the extreme outward position. In turn, the
B1JA type is used for spring-to-open operation; the spring
is between the piston and the cylinder end and pushes the
piston towards the housing.
Spring-return actuators are installed in a manner similar to B1C
series actuators, taking into account the following.
6.5.1Type B1J
Install the actuator so that the piston is in the extreme outward position. The cylinder must not be pressurized and air
supply connections must be open. The valve must be in the
closed position, see Fig. 16.

6.5.2Type B1JA
Install the actuator so that the piston is in the cylinder-end
position at housing side. The cylinder must not be pressurized
and the air supply connection must be open. The valve must
be in the open position, see Fig. 16.
The rest of the installation procedure is the same as for B1C
actuators.
6.6Detaching B series actuators
Disconnect the actuator from its power source;
detach the air supply pipe and control signal cables
or pipes from their connectors.
Unscrew the bracket screws.
Detach the actuator using a suitable extractor, see Fig.
45. The tool can be ordered from the manufacturer.
Fig. 46Installation of a Quadra-Powr actuator and adjust-
ment of the open and closed limits
The actuator must not be pressurized and the air
supply connection must be open.
Turn the valve segment to correspond to the spring
operation: clockwise close, counterclockwise open.
The marker line at the end of the shaft shows the
position, see Fig. 16.
Clean the actuator shaft bore and lubricate it.
Push the actuator carefully onto the valve shaft.
Avoid forcing it, since this may damage the segment

and seat.
Lubricate the actuator mounting screws and screw
them in. Tighten all screws, see Table 4.
Adjust the valve open and closed positions by means
of the screws at the side of the actuator; remember to
tighten the locking nuts. See Fig. 46.
Keep your fingers out of the flow port!
Quadra-Powr actuators may be used for spring-to-close and
spring-to-open operations depending on the installation
position. After selecting the desired operation, see Fig. 46
for the correct installation position.
