1 GENERAL
1.1 Scope of the manualThis manual provides the essential information on theuse of soft seated XA/XT-series ball valves. For furtherinformation on actuators and other instruments, whichare covered only briefly, please refer to separate manu-als on their installation, use and maintenance.
1.2 Valve descriptionXA/XT-series valves are flanged ball valves. The bodiesof the 1" and 1 1/2" valves comprise a single part.Valves 2"–8" have two-piece bodies with bolted bodyjoint. In all models, the ball and the shaft are separateparts and a shaft blow-out is prevented by a shouldermachined on the shaft (1"–1 1/2") or by a pin and retain-ing plates (2"–8").
A spline driver transmitting the shaft torque to the ballconnects the shaft with the ball in sizes 2" – 8". In sizes1" –1 1/2" there is no separate driver part.
The valve is tight in both flow directions. The flexible lipsoft seats are continuously in contact with the ball andthe pressure differential over the valve forces the ballagainst the downstream seat. Construction of thevalves may vary in accordance with customers' wishes.Construction details are indicated in the type code inthe identification plate. For more information about thetype code, see Section 12.
1.3 Valve markingsBody markings are cast or stamped on the body (Fig. 3).The identification plate (Fig. 4) is on the valve flange.
Identification plates have the following markings:
1. Body material2. Shaft material
3. Trim material4. Seat material5. Maximum and minimum operating temperatures6. Maximum shut-off pressure differential/temperature7. Pressure class8. Type code9. Number of the list of valve manufacturing parts10. Model
NOTE:As the use of the valve is application-specific, anumber of factors should be taken into account whenselecting the application. Therefore, some of the situa-tions in which the valves are used are outside thescope of this manual. If you have any questions con-cerning the use or application of the valve, contactMetso Automation for more information.

CAUTION:Do not exceed the valve performance limitations!Exceeding the limitations marked on the valve maycause damage and lead to uncontrolled pressurerelease. Damage or personal injury may result.
CAUTION:Do not dismantle the valve or remove it from thepipeline while the valve is pressurized!Dismantling or removing a pressurized valve will result inuncontrolled pressure release. Always isolate the relevantpart of the pipeline, release the pressure from the valveand remove the medium before dismantling the valve.Be aware of the type of medium involved. Protect peopleand the environment from any harmful or poisonous sub-stances.Make sure that no medium can enter the pipeline duringvalve maintenance.Failure to do this may result in damage or personal injury.
CAUTION:Beware of the ball cutting movement!Keep hands, other parts of the body, tools and otherobjects out of the open flow port. Leave no foreignobjects inside the pipeline. When the valve is actu-ated, the ball functions as a cutting device. Close anddetach the actuator pressure supply pipeline for valvemaintenance. Failure to do this may result in damageor personal injury.
CAUTION:Beware of noise emission!The valve may produce noise in the pipeline. Thenoise level depends on the application. It can bemeasured or calculated using the Metso AutomationNelprof computer program. Observe the relevant workenvironment regulations on noise emission.
CAUTION:Beware of extreme temperatures!The valve body may be very hot or very cold duringuse. Protect people against cold injuries or burns.

2 TRANSPORTATION, RECEPTION AND STORAGE
Check the valve and the accompanying device for anydamage that may have occurred during transport.
Store the valve carefully. We recommend storingindoors in a dry place.
Do not remove the flow port protectors until installingthe valve. Move the valve to its intended location justbefore installation. The valve is usually delivered in theopen position.
3 INSTALLATION AND USE
3.1 GeneralRemove the flow bore protectors and check that thevalve is clean inside. Clean the valve if necessary.
3.2 Installing in the pipeline
Flush the pipeline carefully before installing the valve.Make sure the valve is entirely open when flushing. For-eign particles, such as sand or pieces of welding elec-trode, will damage the ball and seats.
The valve may be installed in any position and offerstightness in both directions. However we do not recom-mend installing the valve with the actuator on theunderneath side because dirt in the pipeline may thenenter the body cavity and damage the gland packing.The position to be avoided is shown in Fig. 9.
It may be necessary to firmly support the pipeline inorder to protect the valve from excess stress. Sufficientsupport will also reduce pipeline vibration and thusensures proper functioning of the positioner.
To facilitate servicing, it is preferable that the valve besupported by the body, using pipe clamps and sup-ports. Do not fasten supports to the flange bolting or tothe actuator, see Fig. 10.
CAUTION:When handling the valve or the valve package,bear in mind its weight!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. 8). Damage or personal injury may result fromfalling parts. The weights are shown in Section 11.
CAUTION:Follow the proper procedures when handling andservicing oxygen valves.
Fig. 7 Storing the valve
Fig. 8 Lifting the valve
CAUTION:When handling the valve or the valve package as awhole, bear in mind the weight of the valve or theentire package!
NOTE:Use screws, nuts, bolts and gaskets equivalent to thefastenings used elsewhere in the pipeline. Center theflange gaskets carefully when fitting the valvebetween flanges.
NOTE:Do not attempt to correct pipeline misalignment bymeans of flange bolting.
Fig. 9 Avoid this mounting position

3.3 Actuator
The valve open/closed position is indicated as follows:
❑ by an indicator on the actuatoror
❑ by a groove at the end of the ball shaft (parallel tothe ball flow opening).
If there is any uncertainty about the indicator, check theball position by the groove.
The actuator should be installed in a manner that allowsplenty of room for its removal.
The upright position is recommended for the actuatorcylinder.
The actuator must not touch the pipeline, becausepipeline vibration may interfere with its operation.
In certain cases it may be considered advantageous toprovide additional support to the actuator. These caseswill normally be associated with large actuators,extended shafts, or where severe vibration is present.Please contact Metso Automation for advice.
3.4 CommissioningEnsure that there is no dirt or foreign objects left insidethe valve or pipeline. Flush the pipeline carefully. Makesure that the valve is entirely open when flushing.
Ensure that all nuts, pipings, and cables are properlyfastened.
Check that the actuator, positioner, and switch are cor-rectly adjusted. Actuator adjustment is explained inSection 6. To adjust the accompanying device refer tothe separate control equipment instruction manuals.
4 SERVICING
4.1 General
Although XA/XT-series ball valves require no regular main-tenance, it is recommended that the gland packing ischecked regularly for tightness. If for some reason the valveshould require maintenance, then a few simple servicemeasures should normally suffice. This section outlines theservice operations that can be carried out by the end user.
The numbers in parentheses refer to the parts list andthe exploded view of the valve in Section 10, if not oth-erwise stated.
4.2 Replacing the packing without removing the valve from the pipeline
The V-ring gland packing requires no regular tighten-ing. The gland packing tightness is provided by thepipeline pressure together with gland pressure againstthe packing rings. In graphite gland packings, tight-ness is ensured by contact between the gland followerand the packing rings.
The gland packing (69) must be changed if leakageoccurs even after the hex nuts (18) have been tight-ened. The V-ring gland packing must be tightened withcare because excess force may damage the V-rings.
❑ Make sure that the valve is not pressurized.❑ Detach the actuator and bracket according to
the instructions in Section 4.4.❑ Remove the key (10).❑ Remove the hexagon nuts (18), disc spring sets
(150), one stud (14) and retainer plates (42,doesnot exist in sizes 1" and 1 1/ 2") and gland (9).
Fig. 10 Supporting the valve
NOTE:When installing the actuator on the valve, make surethat the valve package functions properly. Detailedinformation on actuator installation is given in Section6 or in the separate actuator instructions.
CAUTION:Observe the safety precautions mentioned in Sec-tion 1.8 before servicing!
CAUTION:When handling the valve or the valve package as awhole, bear in mind the weight of the valve or theentire package.
NOTE:Always use original spare parts to make sure that thevalve functions as intended.
NOTE:If you choose to send the valve to the manufacturer forservicing, do not dismantle it. Instead, clean the valvecarefully of all medium and inform the manufacturer ofany dangerous medium involved.
CAUTION:Do not dismantle the valve or remove it from thepipeline while the valve is pressurized!
CAUTION:For safety reasons the retainer plates (42) MUSTalways be installed as shown in 10.2

❑ Remove the packing rings (69) from around thestem using a knife or other pointed instrument.Make sure that there is no damage to the stem orthe counterbore. Please note that the thrust ring(67) may come off as you remove the packing. Itshould be placed back in its position beforeinstalling the new packing.
❑ Clean the packing ring counterbore.❑ Place the new packing rings (69) over the shaft
(5). The gland follower may be used for pushingthe rings into the counterbore. Do not damagepacking rings in the shaft keyway. See Fig. 12.Screw down the removed stud.
❑ Deform the packing rings first by tightening thegland nuts without disc springs to the torque Tt,see the value from Table 1.
❑ Remove the gland nuts and one stud, mount theretainer plates (42) and the removed stud andplace the disc spring sets (150) on the glandstuds. Tighten the nuts (18) so that the discsprings are compressed to the height Hc, seeTable 1. Lock the nuts with locking compounde.g. Loctite 221. See Fig. 13.
❑ Check leakage when the valve is pressurized.
4.3 Repairing a jammed or stiff valve without removing it from the pipeline
Jamming or stiff function may be caused by a flowmedium clogging the seat (7) and the ball (3). The balland the seats can be cleaned without removing thevalve from the pipeline by turning the ball to a partlyopen position and flushing the pipes. If this does nothelp, follow the instructions below.
4.4 Detaching the B series actuator
It is usually easiest to detach the actuator and supportequipment before removing the valve from the pipeline.If the package is small or not easily accessible, it is bet-ter to remove the entire package at the same time.
Please note that the ball seats can be replaced withoutdetaching the actuator.
❑ Close and detach the actuator pressure supplyand disconnect the control cables and pipes.
❑ Loosen the bracket screws.❑ Detach the actuator from the valve with an
extractor that can be ordered from the manufac-turer. See Section 8 Tools'.
❑ Remove the bracket.

4.8 Replacing partsReplace soft parts whenever you dismantle the valvefor maintenance. Replace other parts when necessary.By using original spare parts, you can ensure properfunctioning of the valve. For ordering the spare parts,see Section 9 ('Ordering spare parts').
4.9 Reassembling the valve
4.9.1 Sizes 1"- 1 1/2"❑ Place the valve in a standing position on the pipe
flange end so that the insert thread pointsupwards. Use a surface that will not scratch theflanges.
❑ Screw the insert (2) into the body (1). Tighten theinsert slightly to ensure that it has gone all theway in. Mark the position, e.g. by tapping ascrewdriver lightly against the body at the pointof the mark on the insert, Fig. 16.
❑ Unscrew the insert and remove it from the body.❑ Insert the other ball seat (7) into the body (1).❑ Check that the shaft fits into the ball groove and
remove possible burrs.❑ Insert the ball (3) into the body. Check that the
ball groove is in the right position for mountingthe shaft.
❑ Slip the thrust bearings (70) onto the shaft andpush them against the shaft shoulder. Put thebonnet gasket (66) in its groove, replace the bon-net (8) with the shaft and tighten the studs (13).Tighten the nuts (17) of the studs (13) evenly toachieve uniform compression of the gasket (66).
The torque is 25 Nm when the threads have beenlubricated.
❑ Place the body gasket (65) into the body, on theshoulder at the foot of the threads.
❑ Screw the insert and seat assembly into the body.This is easiest to do if the valve is horizontal.Tighten the insert using a special tool until the capreaches 5-10 mm past the mark made earlier. Thetorque is 160 Nm for 1" and 200 Nm for 1 1/2".
❑ Push the packing rings (69) into their place in thebonnet (8). Tighten the studs (14). Place thegland (9) on the packing (69). See Section 4.2 forpacking assembly instructions.
❑ Mount the key (10).❑ Check the gland packing for leakage when the
valve is pressurized and re-tight the nuts care-fully, if necessary.
❑ Install the valve in the pipeline, as carefully andaccurately as when removed it. Note the instruc-tions in Section 3.
4.9.2 Sizes 2" - 8"❑ Place the valve body on its pipe flange. Use a
surface that does not damage the pipe flanges.❑ Insert the other ball seat (7) into the body (1).❑ Place the retaining ring (51) on the shaft groove
(5). Place the shaft partly inside the body fromabove and place the thrust bearings (70) on theshaft from inside the body. Place the spline driver(4) on the shaft spline and lock it with a pin (50).Screw down the studs (14). Place the thrust ring(67), the packing (69), the gland follower (9) andthe retaining plates (42) in their position. Placethe nuts (18) on the studs (14) and screw downthem gently.
❑ Put the ball (3) in its position so that the splinedriver is in the ball slot.
❑ Place the body gasket (65) in the body groove.Screw the studs (12) into the body (1).
❑ Place the other ball seat (7) on the ball (3).❑ Carefully place the body cap (2) on the body.
Make sure that the marks made during disman-tling are aligned.
❑ Fasten the body nuts (16). Tighten the nuts grad-ually, always switching to other side of the valveafter every nut. The recommended torques aregiven in Table 2. The flange faces must be ineven contact with each other.
❑ Mount the key (10).❑ Deform the packing rings by tightening the gland
nuts without disc springs to the torque Tt, see thevalue from Table 1, see Section 4.2.
❑ Remove the gland nuts and one stud, mount theretaining plates (42) and the removed stud andplace the disc spring sets (150) on the gland studs.Tighten the nuts (18) so that the disc springs arecompressed to the height Hc, see Table 1. Lock thenuts with locking compound e.g. Loctite 221.

5 TESTING THE VALVE
Test the valve's body pressure after reassembly.
Test the pressure in accordance with an applicablestandard. Use the pressure required by the pressureclass or the flange bore. Keep the valve in the half openposition during the test.
If the tightness of the closure member is also to betested, please contact the manufacturer.
6 INSTALLING THE ACTUATOR
6.1 GeneralUse suitable mounting parts and couplings when youinstall the actuators.
6.2 Installing the M-type manual gear operator
❑ The mark at the end of the shaft indicates thedirection of the ball flow bore. Turn the valve tothe closed position.
❑ Lubricate the grooves of the actuator and thecouplings. Place the coupling on the shaft andlock it. Place the bracket on the valve and turnthe lubricated screws a few times. A plate shouldbe installed between the valve flange mountingface or bracket and the actuator mounting face,see actuator's instructions for details.
❑ Turn the actuator to the closed position and pushit carefully onto the valve shaft on which the cou-pling has been mounted. Please note the markson the handwheel and the coupling.
❑ Lubricate the actuator screws. Tighten allscrews.
❑ Adjust the ball open and closed positions withthe hexagon screws located at the side of thehousing (see Fig.17). The stop-screw for theopen position is nearest to the handwheel on theside of the housing and the screw for the closedposition is at the opposite end. The turning direc-tions for the handwheel are marked on the wheel.
❑ Check the valve by turning the handwheel to theextreme positions. The yellow arrow should indi-cate the direction of the ball flow bore.
6.3 Installing the B1C-series actuator❑ Turn the valve to the closed position and drive
actuator piston to the extreme outward position.❑ File off any burrs and clean the shaft bore .❑ The line at the end of the shaft indicates the
direction of the ball flow bore.❑ Lubricate the actuator shaft bore. Fasten the
bracket loosely to the valve.❑ Slip the actuator carefully onto the valve shaft.
Avoid forcing it since this may damage the ball

and seats. We recommend mounting the actua-tor so that the cylinder is pointing upwards.
❑ Position the actuator parallel or vertical to thepipeline as accurately as possible. Lubricate theactuator mounting screws and then fasten allscrews.
❑ Adjust the ball open and closed positions bymeans of the actuator stop screws located atboth ends (see Fig.18). An accurate open posi-tion can be seen in the body flow bore.Check that the yellow arrow on the actuator indi-cates the ball flow opening position. Keep fin-gers out of the flow bore!There is no need for stop screw adjustment if theactuator is re-installed in the same valve. Driveactuator piston to the housing end (open posi-tion). Turn the actuator by hand until the valve isin the open position. Fasten the actuator in thisposition as explained above.
❑ Check the stop screw thread tightness. Thethreads must be sealed using an appropriatenon-hardening sealant, e.g Loctite 225.
❑ Check that the actuator is functioning correctly.Drive the actuator piston to both cylinder ends andcheck the ball position and its movement withrespect to the actuator (close: clockwise; open:counterclockwise). The valve should be closedwhen the piston is in the extreme outward position.
❑ If necessary, change the position of the actuatorpointing cover to correctly indicate the valveopen/closed position.
6.4 Installing the B1J-series actuatorSpring-return actuators are used in applications wherevalve opening or closing movement is needed in casethe air supply is interrupted. The B1J type is used forspring-to-close operation; the spring pushes the pistontowards the cylinder end, the extreme outward position.In turn, the B1JA type is used for spring-to-open opera-tion; the spring pushes the piston towards the housing.
Spring-return actuators are installed in a manner similar toB1 C-series actuators, taking into account the following.
6.4.1 B1J-type❑ Install the actuator so that the piston is in the
extreme outward position. The cylinder must notbe pressurized and air supply connections mustbe open. The valve must be in the closed posi-tion.
6.4.2 B1JA-type❑ Install the actuator so that the piston is in the cyl-
inder end position at housing side. The cylindermust not be pressurized and air supply connec-tions must be open. The valve must be in theopen position.
The rest of the installation procedure is the same as inSection 6.3.
6.5 Installing EC and EJ actuatorThe actuator is attached to a bracket via an ISO 5211standard mounting interface. The actuator is adaptedto the valve shaft with a separate bushing. The bushing(II + II) is a two-piece cone-shaped bushing, which istightened firmly with a tightening screw (I) around thevalve shaft.
❑ Mount the bushing and the tightening screw fromthe mounting interface side of the actuator,according to Fig. 20. Insert cylindrical pins (III) inthe bushing slots, these must be directed into thecorresponding slots in the actuator during tight-ening. Before the installation of the bushing andthe tightening screw, remove impurities such asold threadlocking material from the threads of thetightening screw, and apply Loctite 243 or similarthreadlock carefully to the threads, as shown inFig. 20. Turn the tightening screw from inside theactuator shaft using a suitable hex key.
❑ Prior to installation, the correct shaft position ofthe valve has to be checked. In the key-typebushing there are four keyways, two of which areintended for valves with DIN key and two forvalve shafts with ANSI key. The DIN keyway islocated in the middle of the half bushing, and theANSI keyway is located in the split between thebushing halves. Fig. 21 shows the keyway posi-tion when the actuator is in a closed position.
❑ The open or closed positions of the actuator canbe identified either by using compressed air, seeFig. 19, or by checking the position of the pointer

at the end of the drive shaft. The actuator is closedif the pointer on the coupling plate is transverse tothe direction of the actuator’s main shaft.
❑ In the bushing having square head connectionchecking the right position is more simple. Usethe pointer in the end of the drive shaft to see thecorrect position Mount the actuator to the valvebracket with four screws. The tightening screw ofthe bushing should be loosened before mount-ing, to allow the shaft to fit easily into the actuator.
❑ The actuator construction allows axial movementof the drive shaft. Check, before the screw is tight-ened, that the drive shaft is in the upper position ofits axial movement, which is its normal position(the mounting position shown in Fig. 22). Check-ing is important, as the actuator shaft drops downslightly when the screw is tightened. The driveshaft axial movement can be observed and meas-ured before attachment to a valve. The actuatordrive shaft is in the upper position when its uppersurface conforms to Table 3 (see also Fig. 22).
❑ The drive shaft will automatically find its correctposition when the tightening screw is tightened, ifthe installation tool is used (Fig. 22). The installa-tion tool is attached instead of the coupling plateusing M4 screws with the drive shaft in upperposition (before the valve is installed). Tighten thescrews in such a way that the tool is tightenedagainst the upper surface of the housing.
❑ Install the actuator on the valve and attach theattachment screws normally. Finally, tighten thetightening screw according to Table 3. Therequired torque is also marked on a plate closeto the drive shaft on the actuator housing. Theinstallation tool is removed, and the couplingplate is reattached.The valve may malfunction if the tightening ofthe connection has been carried out improperly.
❑ Finally, the extreme positions of the valve areadjusted with the stop screws at the ends of theactuator. The location of the screws for adjustingthe Close and Open positions of the valve aremarked with letters on the ends of the actuatorhousing (see Fig. 19).
6.6 Installing DC and DJ actuators, sizes 1"-3"
Turn the valve to the closed position. Please note thecorrect position of the actuator stem. The groove at theend of the actuator stem indicates the direction of theball flow bore. Push the actuator onto the stem with orwithout a coupling, and fasten with four screws.
