In this Manual dangers, risks and items of safety information are highlighted to attract special attention.

Informationmarkedwiththesymbolabovedescribespractices,whichiffailtocomplywith,canresultinseriousinjuryor

danger of death for users or third parties or in material damage to the system or the environment. It is vital to comply with

these practices and to monitor compliance.

TherestofinformationnotspecicallyemphasizedinthisManual,alongwithDataSheetandproductmarking,mustalso

beobservedandcompliedwithforsafelyusingtheproduct.

3. PRESERVATION, STORAGE, HANDLING & TRANSPORT

ATTENTION!

- Protect against external force (impacts, vibrations, etc.).

- Allow only skilled personnel; suitable handling and lifting equipment must be used. See Data Sheet for weights or

consult manufacturer.

- Always use suitable protection equipment, and minimize the use of human body force at any step to avoid injuries.

-During handling make sure that operating device is well attached to the valve or removed to avoid danger of de-

tachment. Product parts such as handwheels, actuators or hoods must not be used to take up external forces that

they are not designed for: e.g. do not use them as climbing aids, or as connecting points for lifting gear, etc.

- There is a risk of body member (hand, nger, arm…) crushed against any other solid element (wall, pipe, oor, etc.)

during handling. Take this into account and handle with care.

- There is a risk of body member trapped between valve disc and seat during operation of the valve. Make sure no

operation / supply to actuator disconnected if access to the interior of the valve.

- There is a risk of body member injury in case there is any exposed moving part between valve and actuator (spe-

cial arrangements). Take appropriate measures and set warning notes when required.

- Check correct position of nameplate and handle with care to avoid personnel cuttings.

- Use proper packing for transportation.

-Keepstorageprotectionbeforeinstallation.

- Keep the valves in a slightly open position. Keep exposed machined surfaces cleaned and greased when necessary.

- In order to prevent damage, corrosion or rust on the surface, avoid extreme temperatures (keep at 5ºC to 50ºC), avoid

highenvironmentalhumidityorcorrosiveenvironment.Keepthevalvesawayfromdirectsunlight,dust,amesorrain.Do

notpileupexcessiveweight.Incaseofseverebumpinginspectthematerialforanydamageandreplaceifnecessary.

5.1Generalremarksoninstallation

Thefollowingpointsshouldbetakenintoaccountinadditiontothegeneralprinciplesgoverninginstallationwork:

ATTENTION!

- Before installation, make sure previous chapters are thoroughly followed.

- Ensure safe access and working conditions for proper performance.

- Only operate the valve while observing all the safety measures.

- Remove ange covers or any other remaining packing/storage protection if present.

- Lay pipelines such that damaging transverse, bending and torsional forces are avoided.

- Protect valves from dirt during construction work. The interior of the valve and the pipeline must be free of foreign

particles.

- Protect the valve soft parts from heating caused by welding works at the plant during commissioning.

- Avoid mechanical damage to the seat.

- The valve is unidirectional. Follow the arrow in the body for installation. Valve optimal position is horizontal. Avoid

any of the globe valves’ stem pointing downwards.

NAME PLATE FEATURES:

-Nameplate in stainless steel plate, with two holes, to be riveted on the valve with st. steel pins or if not possible aluminium pins

-Nameplate size to be proportional to valve size (i.e. avoid too small nameplate for big size valve or too big nameplate for small size valve).

To avoid worker damage during handling:

-Nameplate to have chamfered corners.

-Nameplate should never protrude from valve surface.

-Nameplate location:

If casting has a specific place for nameplate, to be riveted on this place.

If casting has no specific place for nameplate:

Gate-Globe-Check-Plug Valves: to be riveted in the body flange (flange that is bolted to bonnet flange)

Ball Valves: to be riveted on the top flange.

When drilling holes for riveting, be careful with distance between holes to avoid tensions on the nameplate once riveted, and avoid places where drilling could cause

valve leakage.

NAME PLATE FEATURES:

-Nameplate in stainless steel plate, with two holes, to be riveted on the valve with st. steel pins or if not possible aluminium pins

-Nameplate size to be proportional to valve size (i.e. avoid too small nameplate for big size valve or too big nameplate for small size valve).

To avoid worker damage during handling:

-Nameplate to have chamfered corners.

-Nameplate should never protrude from valve surface.

-Nameplate location:

If casting has a specific place for nameplate, to be riveted on this place.

If casting has no specific place for nameplate:

Gate-Globe-Check-Plug Valves: to be riveted in the body flange (flange that is bolted to bonnet flange)

Ball Valves: to be riveted on the top flange.

When drilling holes for riveting, be careful with distance between holes to avoid tensions on the nameplate once riveted, and avoid places where drilling could cause

valve leakage.

ATTENTION!

- When using the valve as an end seal, the employers’ liability insurance association of the gas and waterworks

species the use of a safety precaution such as a plug-in disc, blind ange, etc. With a medium jet that freely

exists, you must secure the exit area.

- When installing the valve, there is a crushing hazard between valve and pipe system. Mind the hands to avoid it.

Flanged ends valves:

- Make sure that counter-anges are compatible with the standard of the valve anges. When matching up anges,

avoid gradients, rotation and pipe misalignment that could cause pipe and valve stress and leakage once installed.

Flanges should t smoothly. Select the proper ange face gaskets according to duty and centre them on the ange

face properly. Do not force the counter-anges and do not try to tighten the bolts when a gap exists between valve

and pipe or if misalignment is observed. Tighten in a crosswise, moderate and uniform manner.

Screwed ends valves:

- Make sure that the pipe screw has the correct nish and compatible cone for the valve.

- Use proper sealant according to duty, such as hemp core, Teon, etc.

- Check that pipe introduction in the valve does not exceed its thread, leave a safety margin of minimum 1 mm.

- Tighten with a plain or adjustable wrench on the hexagon end of the valve only. Apply force to other area of valve

may seriously damage the valve. Do not use hook spanners or other wrenches that could damage the hexagon sur-

face. Valve should be threaded smoothly. If not, do not try to force the thread and avoid wrench extensions since this

could lead to breaking the valve or damaging the thread. A general recommendation is not to exceed the tightening

torque of 30Nm.

5.2Requirementsattheplaceofinstallation

- Aggressive environmental conditions may reduce the life span of the product. Consider special construction/protective

measures in such a case.

-Considertheinteractionbetweenthesystemandtheequipment.Foreseeelementstoabsorbvibrations,pipedilata-

tions, guides, anchoring and proper support according to the weight of the components.

-Thesystemandoperationprotocolshouldbeconceivedinsuchawaytoavoidhighvelocitiesandcavitation.Prevent

pulsingoworwaterhammers,whichareveryharmfulforvalvesandtherestofthecomponents.

- Flooding of the product is not recommended.

- Allow enough space for valve installation, operation and maintenance.

-Itisrecommendedtoinstallapropersizedmeshstrainerupstreamthevalveinordertoprotectseatingsurfacesfrom

abrasionorerosionthatcouldleadtoseatleakage.

6. COMMISSIONING & OPERATION

ATTENTION!

- Before commissioning the valve, check the material, pressure, temperature and other essential parameters.

Always use the product within the scope of intended service and operating duties.

- Before commissioning, make sure previous chapters are thoroughly followed.

- Regional safety instructions should be adhered to.

- It is essential to ush the pipe system thoroughly to eliminate all the particles and impurities which could remain in

the pipes and particularly welding residue, chips, tool remains, etc. that could damage the equipment during start-

up. Ensure that during cleaning of the pipe system, any chemicals used and temperature are compatible with the

valve construction.

- Temperatures above 50ºC or below 0ºC may cause personnel injuries if valves are touched.

- Leakage of media through valve stem, connections or at closing (end of pipeline) may also cause scalding, health

harm, pollution, re or damage to other parts of the installation depending on the media. Use suitable protection

equipment when approaching the valve, ensure that the corresponding warning signs are displayed on the valve or

surrounding area, and/or isolate the equipment in case of danger.

- Before commissioning a new plant or restarting it after repairs or modication, always ensure that:

- All work has been completed correctly.

- The valve is in the correct position for its function.

- Safety devices/measures have been implemented.

- Valve operation, lling, warming-up and starting-up shall be gradual so as to avoid any inadmissible stress. Check

for tightness in valve connections, body/bonnet union, and stem, and retighten crosswise and gradually if necessary

until leakage elimination.

- For steam systems, proper system layout and operation procedure should be well established and followed. It is

essential to ensure condensate properly drained, gradual lling of the system and slow valve operation to avoid

water hammer / thermal shock do to revaporizing

- Valves with packing: The packing is tightened at factory in a moderate way to pass the pressure tests. After a while

before installation, packing rings experiment a relaxation and some retightening might be needed during start-up.

Over tightening the bolts will increase operating torque, and will reduce life of the packing. Also after several open

and close ooperations of the valve the stem gains some play with the packing rings, thus packing tightness should

be checked periodically and retighten gradually when necessary.

- Ensure valve surface is in good condition and retouch coating protection when needed.

-Oncethevalveinstalled,makeaninitialopeningandclosingoperationtocheckitsproperoperability,withoutadditional

tools.

-Incaseofriskofmediafreezinginsidethevalve,takeduemeasurestoavoidit.

7. CARE AND MAINTENANCE

Theoperatormustdenemaintenanceandmaintenance-intervalstomeetrequirements.

-Checkforbody,seatandconnectionstightness,andvalvesmoothoperationwithoutadditionaltools.

ATTENTION!

- In the event of infrequent use, operate the valve as frequently as possible to avoid deposits of dirt and valve

blocking.

- Before disassembling the valve, note chapters 3, 10 & 12.

- Only carry out maintenance work in the pipework when the valve has been secured from operation.

- Check the valve surface inside and outside and retouch coating protection when needed. If advanced corrosion

or erosion is observed, double check service and valve features and replace the valve properly.

- Keep exposed machined surfaces cleaned and greased when necessary.

-Ifthevalveisleakingthroughthestem,tryrsttoretightenthepackingglandwithoutcompromisingstemsmoothmove-

ment.
