Informationgives useful tips and recommendations.

LEUSCH valves are designed in accordance with applicablestandards in compliance with technical regulations (e.g. AD-2000 regulations) and the European Directive for PressureEquipment 2014/68/EU.For intended usage it should be ensured that the valves areonly used where the operating pressure and temperatures donot exceed the design criteria specified for the order. Themanufacturer is not responsible for damages arising fromexternal forces or other external influences! Risks which arisefrom the process medium, operating pressure and tempera-tures, as well as from the signal pressure or from movingparts of the valve, should be prevented by suitable measures.The following must be ensured for the intended usage of thedevices:

Implementation and operation of the valves inpipelines within predefined (materialdependent)pressure and temperature limits (see informationsfor PS and TS on the name-plate) for control andshutting-off of the fluid by means of manual gear-box or by means of a actuator (pneumatic,electric or hydraulic).

When Valve is to be used as End-Valve, the oper-ating and ambient conditions must first be clarifiedwith the manufacturer.Valves with wafer body are designed only forinstallation between two mating flanges and there-fore not suitable for use as End-Valve.

Installation and operation of the valves with re-spect to no additional adverse effects such aspipeline forces, wind loads, vibrations (also earth-quakes), corrosion, fire or decomposition of unsta-ble fluids.The plant designer/operator is responsible for takingrelevant measures to prevent additional loads andinfluences and therefore possible risks to the valvesand the environment, as appropriate. Suchmeasures could be, for example:

Construction of load restraints and vibrationdampersMeasures for safe drainage or redirection ofdangerous mediums (from external leaks)Measures for process safety when auxiliaryenergies fail (e.g. consideration of fail-safe posi-tions)Correct storage and transport of the valves (e.g.dry storage, use of suitable sling materials etc.)

Use of the valves with fluids that the select-ed materials are sufficiently resistant to.The fluid compatibility of the valves (in regardto the materials used including the sealingmaterials) is to be checked by the plant de-signer /operator for all operating conditions.Temperature change as well as applicableuse of future detergent must also be takeninto consideration.Measures to ensure the fluid compatibilityby the plant designer /operator could be, forexample:

• Specification of suitable materials• Specification of protective coatings• Creation of (special) specifications

Specification of the flow velocity depending onmedium as well as the use of the valves, sothat no damage can occur to the valve and thepipeline.

CEFor valves with CE labelling (CE name-plate)the conformity in accordance with EuropeanDirective for Pressure Equipment 2014/68/EUwill be declared. The conformity declarationgives information about the conformity assess-

In addition, the same safety regulations apply forvalves as for the pipeline system in which theyare installed.The safety regulations of the attached controlsystem for the actuator including accessoriesare also to be observed, as well as the instruc-tions and regulations of the individual manufac-turer.

Further safety instructions that are to be fol-lowed for the installation, operation and mainte-nance of the valves are described in the follow-ing chapters.

NACEIn relation to the use or the application of mate-rials in accordance with NACE MR0175 /ISO15156 as well as NACE MR0103 (Materialsin environments containing H2S), the designa-tion of the standard itself in the material or testcertificates does not yet certify suitability for theuse of the valve. This is additionally dependenton operating and environmental parameters,which are usually only provided by the plantdesigner. Therefore, the suitability of such avalve is always to be checked by the plant de-signer/operator.

SILThe suitability for the use of valves in (SIL)protective circuits must be documented in spe-cial agreements. The requirements that are tobe followed are described in standards (e.g.VD12180, EN 61508) and in the applicableSamson group handbook (functional safety forEN 61511control valves, rotary plug valves, ballvalves and butterfly valves; WA 236.

Oxygen serviceDuring ordering of spare-part kits for valvesthat are used for oxygen service, it is neces-sary to specify explicit “OXYGENE-SERVICE”.

Instructions, intended usage

3 Industrial Valves

Check whether the valve was damaged during transport orhandling. Damage must be notified within 14 days of arrival.The transport instructions on the packaging (e.g. wooden box)must be followed. It must be ensured through suitable and ap-proved sling materials and slings that no damage can occur toconnector surfaces, as well as preventing other adverse effectson the device (e.g. actuator accessories, pipeline, sealing ele-ments). The device may not be lifted up directly on the actuator.A sling should be attached for larger valves.(Examples are shown in Fig. 1 and Fig. 2)Ensure storage in the original package in an enclosed area.This is to be done in a clean and dry environment in compliancewith the permissible ambient temperatures for the valves.Do not lay the valve directly on the floor. Suitable supports(e.g. delivery packaging) should be used to protect the deviceagainst particles/dirt during storage and installation.Protective enclosure and packaging should be removed im-mediately before installation of the valve. This applies particu-larly to special packaging (e.g. for specially cleaned valves).

Transport, storage and handling

Installation

ATTENTION: DANGER! Spring-acting actuators may only bepressurised in assembled condition in the pipeline, and notfor the purposes of performance of work on the valve outsidethe pipeline. There is a risk of fatal injury if the auxiliary ener-gy suddenly fails and the valve disc then moves on its owninto the fail-safe position as a result of spring decompression.For devices equipped with a spring return actuator with safetyposition “Open” (Fail open), the valve disc may possibly needto be closed for installation in a pipeline. It must be ensuredhere that the full control pressure for closing the valve is main-tained for the duration of the installation work. Otherwise, thevalve must be installed in the open position, e.g. by disman-tling the pipeline.

1. For installation, it must be ensured that:Sufficient installation space is availableThe pipeline connectors are well alignedSuitable installation tools and lifting attachments areusedPrecautions for the prevention of contact with danger-ous fluids have been taken.

2. Furthermore, it must be ensured that:Employees or third parties are not at risk. If applicable,legal regulations of the country of destination must ad-ditionally be observedIt is accessible for necessary inspection, and can beobserved from all sides, if necessaryThe operation of all components is possible from a safepositionThe name-plate is recognisable.

3. The device is to be connected to the appropriately designnated supports/connectors. It must be protected againstexternal mechanical influences to the extent that damage isnot expected on the device. The preferred flow directionmust be observed during installation. It points from the shaftaxis in the direction of the sealing seat and is marked byarrows at the sides of the valve body.

4. The disc should be closed during installation of thevalve.

5. The following must be ensured for the weldingwork to be carried out:All welded connecting joints are made andchecked in accordance with current and recog-nised welding procedures.They are only carried out by specialist personnelin compliance with the relevant regulations.Overheating of body and trim is avoided.The valve is closed to protect sealing elementsfrom welding beads and dirt.

6. If there is a risk of static charge on the device,the operator must ensure that a suitableground / earthing connection is installed to pre-vent this.

7. Butterfly valves in Series LTR43-2, LTR43-5 andLTR43-9 have a non-continouis sealing surface.In Case of Sealing Surfaces acc to EN1092-1(B1 and B2 only) and ASME (B16.5 RF andB16.47 RF), please consider flat Gasket typeacc. To EN 1514-1 and ASME B16.21 respec-tively. For the use of spiral-wound- or kammpro-file-gaskets, non-standard dimensions have tobe requested from Leusch GmbH.

General installation instructions:A minimum gap of 5 x pipe diameter must be kept fromthe next component upstream and downstream of thevalve (e.g. pump valve or elbow). If it is not possible tomaintain the prescribed gap due to technical reasons,we recommend installing the valve in the following posi-tion. The valve shaft and centre of the elbow cross-section should be arranged parallel to reduce the dy-namic forces on the disc (Fig. 3).For installation on the pressurised side of a centrifugalpump, the valve shaft must be arranged at a 90° angleoffset to the pump shaft (Fig. 3).

Commissioning, operation, de-commissioning

1. Commissioning of the device may only be carriedout once the operator has ensured that:All installation work has been completed on thepipeline and the device has been correctly in-stalled in the system.The pipeline and valve are free of dirt and parti-cles to ensure faultless functioning (opening/closing). Residue and operation with fluid thatcontain a high proportion of particles could leadto functional breakdowns and shortened mainte-nance intervals. If this is to be expected, addi-tional suitable measures must be planned for theprevention of faults, if necessary. The systemshould therefore be thoroughly cleaned beforecommissioning. If necessary, it is recommendedto remove the valve from the pipeline and to re-place it with adaptersThe device has been checked for proper condi-tion in regard to installation and safe functioning.

2. In particular, it should be checked and ensuredthat:The valve disc does not collide with the pipelineduring opening/closing.

The parts which come into contact withfluid are suitable for the planned usage.Actuators and accessories (if available)are connected in accordance with man-ufacturer's instructions and the devicefunctions correctly corresponding to thecontrol commands.The IP and EEx labelling/details arecorrect for electrical components.The limit values on the name-plate, suchas maximum permissible pressure PS ofthe valve, minimum/maximum tempera-ture TS will not be exceeded due to theoperating conditions (P < PS, TS min. < T< TS max.). In addition, the pressure/temperature Rating in accordance withEN 12516, EN 1092 or ASME B16.34must be observed.

3. The operator must operate and monitorthe device using trained personnel sothat employees and third parties are notendangered. If applicable, nationallyrelevant regulations of the country ofdestination should also be observed forthe operation of the device.

4. Modifications to the factory settings foractuators (e.g. limit stops) and accesso-ries (e.g. filter regulator, booster) are notpermitted and may only be carried out inindividual cases with the approval of themanufacturer by qualified and specialisedpersonnel.

5. ATTENTION: The valve disc must beopen when performing a pressure Test ofthe pipeline system. It must be ensuredthat the maximum permissible pressurefor the valve is not exceeded. Seals(flange, cover, gland, or extension, if ap-plicable) must be checked for leakage. Ifthe Packing Gland leaks, the nuts of thegland should be alternately tightened insmall steps until the leak is fixed.Never tighten nuts more than necessaryMaximum torques Page 8 Tab.1.If there is still a leak, the manufacturershould be contacted.

6. The system is to be started up orstopped so that no impermissible volt-age increases result from the tempera-ture rise/fall. The device must be con-stantly observed during starting opera-tion and checked for possible leaks.

7. In normal operation, the device may onlybe operated when all components of thedevice are functional and have not beendeactivated or changed in their intendedfunction.

8. Operating the valve in constant throttlingposition at a small opening angle maylead to increase wear of the sealing ele-ments (seat/seatring). This will possiblylead to shorter maintenance intervals.

9. When decommissioning the device, allsafety notes in the “Maintenance and ad-justments” chapter must be observed. Thedisposal of the device must be carried outin accordance with the operational andnational regulations of the destinationcountry. The relevant operating instruc-tions of the installed components or acces-sories must also be followed here.

5 Industrial Valves

Function

LEUSCH LTR 43 butterfly valves usually have a metal seat.Other material alternative for the seat and seatring are stain-less steel / graphite, PTFE and stellite. Special coatings andspecial materials are available per customer request.The valve has optimal sealing characteristics when it isaligned according to the preferred flow direction during instal-lation in the pipeline system (Fig. 4).The preferred direction of flow is marked by an arrow at theside of the valve body.Thanks to its unique geometric design, the disc is presseduniformly against the body seat across its whole surface area.The valve is adjustable. If subsequent adjustment of the limitstops becomes necessary (refer also to “Maintenance andadjustment”), this may only be done by qualified and knowl-edgeable personnel and with the consent of the manufacturer

The Triple offset is distinguished by the following characteristics:1. OS (Offset): The shaft bearing has an axial offset to the seatlevel, 2. OS: The shaft bearing has a radial offset to the center ofthe body, 3. OS: the center of the conical seat surface has a radi-al offset to the center of the body. (Fig. 4)

Maintenance and adjustment

All measures necessary for maintenance and repair shouldbe carried out in accordance with the national regulations ofthe destination country.

It is recommended to check the device regularly for externalleaks and other adverse effects or anything conspicuous.The Gland Packing usually consists of a set of form-pressedexpandable rings. In the event of a leakage, the nuts on theGland must be alternately tightened in little steps until theleak stops. It has to be ensured, that the gland is always par-allel to the body surface (Fig 5).If necessary, add additional packing rings. Observe the maxi-mum permissible torques (see “Replacing the Gland pack-ing”) or Page 8 table 1, if only torque values are required.Complete Packing and repair sets for maintenance of thevalves are available from LEUSCH or/and the authorisedLEUSCH representative.

Before contacting your representative or Leusch GmbH,please make a note of all the details on the name-plate of thevalve (Fig. 11).

ATTENTION: DANGER! Spring return actuators may only bepressurised only when assembled in the pipeline and not forthe purposes of performance of work on the valve outside thepipeline. There is a risk of fatal injury if the auxiliary energysuddenly fails and the valve disc then moves on its own intothe fail-safe position as a result of spring tension.

For devices equipped with a spring return actuator with FailOpen safety position, the valve disc may possibly need to beclosed for installation in a pipeline. It must be ensured herethat the full control pressure for closing the valve is main-tained for the duration of the installation work.

Otherwise, the valve must be installed in the openposition, e.g. by dismantling the pipeline.Caution should be taken also on devices withspring-return actuators, for example, that does notcarry out any functiondue to being clamped in place and therefore re-main in any closed/open position. The returnspring could be decompressed at any momentwithout active/connected auxiliary energies thussetting the valve disc in motion.LEUSCH valves may only be assembled, put intooperation and maintained by specialist and trainedpersonnel in accordance with recognised technicalrules. Ensure that employees and third parties arenot endangered. The operator must define thenecessary measures for maintenance in the oper-ating instructions. All safety or warning instructionsdetailed here and in the product instructions (e.g.operating and maintenance instructions) must befollowed.For valves which are used in oxygen service, allmaintanance and repair works has to be carriedout in an oil-and greasefree enviroment. All partsmus be clean and free from oil and grease. Onlysuitable lubricants are permitted.

During maintanance and adjustment works, thefollowing issues have to be considered

1. Before starting work on the device, ensure that:all energy supply lines and control signals of theactuator are disconnected or locked so that theactuator cannot unexpectedly set the valve discin motionthe affected system part is de-pressurised andthe pipeline has been emptied. Special precau-tions must be taken (e.g. personal protectiveequipment) if there is a risk of escaping fluid.Parts which are to be processed have cooled orwarmed up to ambient temperature to preventburns from (skin) contact.the valve disc is in the closed position in caseswhere the valve must be removed from the pipe-line.

2. Never loosen or tighten fastening elements (e.g.screws/bolts) on parts when they are pressur-ised.

3. No manual gear or actuators may be disassem-bled when the butterfly valves are pressurised.

4. Visually check the device at regular intervals forcontamination, corrosion, leaks, functionality andother adverse effects. Further points to bechecked may include: Usability, settings on thecomponents, labels, coating and conductivity

5. In the event of leaks on the gland packing, alter-nately tighten the nuts on the gland in smallsteps. Do not tighten nuts more than necessary.Comply with the maximumtorques Page 8, Tab. 1

6. Modifications to the factory settings for actuators(e.g. limit stops) and accessories (e.g. filter regu-lator, booster) are not permitted and may only becarried out in individual cases with the approvalof the manufacturer by qualified and specialisedpersonnel.

7. Only use original spare parts for maintenance/repairs. These are available on request

8. During reassembly in the pipework the note insection 7 has to be considered

9. After finishing the service/repair, a hydrostaticpressure test on the pressure loaded parts has tobe executed according to a suitable test proce-dure

10.Valves which are not actuated for long periodsmust undergo functional tests on a regular basis.If necessary, shorter maintenance intervals maybe required if increased wear is expected on thesealing elements (e.g. through abrasive, chemi-cal or other adverse effects).

11.Valves for the SIL (Safety Integrity Level) Appli-cation must be handled according to the follow-ing standards in regard to maintenance and re-pair: - VDI 2180, -EN 61511,- EN 61508,Manual WA 236

Limit stop adjustmentIf necessary (e.g. in the event of impermissi-ble leakage on the sealing element of thevalve), the adjustment pressure betweenSeat and Seatring can be changed by adjust-ing the limit Stop position at the actuator.ATTENTION! Settings may only be changedby specialist personnel, with the approval ofthe manufacturer, who are familiar with thehandling and setting of such devices. Theinstructions in the operating instructions ofthe actuator for setting the limit stops mustalso be followed unconditionallyBefore settings are changed, a functional testshould first be carried out as follows:

Open the valve fully to flush out possiblesolids from the sealing surfaces of Seatand Seatring.

Close the valve and check whether thevalve closes correctly (there should beno solids stuck between the Seat andSeatring).

The following procedure is recommended ifno improvement has been achieved:

1. Loosen the lock nut for the limit positionstop and slightly open the valve until thestop has been cleared.

2. Turn the adjustment screw by 1/4 turnsin counter clockwise direction and clos-es the valve again. Check for leakageintegrity.

3. If the result is satisfactory (observingthe permissible leakage rate), tightenthe lock nut again while the valve disc isclosed.

4. Otherwise repeat step 2. However, theadjustment screw should not be un-screwed by more than 1 revolution alto-gether.

5. If the leakage rate remains impermissible,the sealing pair (Seat/Seatring) may pos-sibly be damaged and must be examinedmore closely (e.g. replacing the Seatring).The manufacturer should be notified inthis case.

Labeling

The devices are labelled with a metal name-plate, which is usually attached to the valve or to another suitable part of the deviceif necessary (e.g. extension, bracket). Conformity with the European Directive for Pressure Equipment is confirmed when thename-plate has a CE symbol with the ID number of the notified body (see Fig. 11).The following details can be taken from the plate: Manufacturer, device type (type), nominal diameter (DN or NPS), nominalpressure (PN or CL), order number (P.O.), permissible pressure (PS), permissible temperature (TS), Maximum permissibledifferential pressure on the shut-off element (P shutoff trim), year and month of manufacture (date), fluid group and (tag no.), ifavailable.The preferred flow direction of flow is marked by a directional arrow integrated in the valve body or affixed to the valve body ata suitable location.Further information may be available on additional metal plates.

Service

It is recommended to check the device regularly for external leaks and other adverse effects or anything conspicuous.The Gland Packing usually consists of form-pressed expandable rings. In the event of leaks, alternately tighten the nuts on thegland until the leak stops. If necessary, add additional packing rings. Observe the maximum permissible torques (see“Replacing the gland packing”) or Page 8 table 1, if only torque values are required.Complete packing and repair sets for maintenance of the valves are available from LEUSCH or/and the authorised LEUSCHrepresentative.To select the right spare part kit, note all informations from the name- plate and communicate this to LEUSCH.
