general information

IntroductionLCM Italia designs and manufactures isolation quarter turn ball valves for Oil & Gas and Petrochemical Industry.LCM valve product stands on the highest quality and performance levels among the Italian ball valve manufacturers.

ProductrangecoversmanualoperatedandactuatedOn-Offvalvestoserveseveralapplicationsandfluidstohandle:oil,gas,con-densate, water, steam, various chemicals and aggressive media. All valves are designed by LCM Italia Engineering Department using the most advanced CAD & FEM software.

Valve body and trims are manufactured from forged or casted raw materialsproducedbythemostqualifiedO&Gsubsuppliers.

Trunnion-Mounted Ball ValvesAPI-6Dvalvesareavailableinthefollowingdesignconfiguration:• SideEntryboltedbodyintwoorthreepiecesconfiguration• Welded Body obtained from 2/3 pieces forged rings and/or

tion)

Floating Ball Valves (seat supported)ISO-17292 (formerly BS 5351) valves are with following body design:• Split Body (two pieces bolted body forged or casted)• Monoblock (two pieces bar stock, with threaded body con-

struction)FBV are available with thermoplastic seats (seat supported) or with metalseatedconfiguration.Seal selection and valve features are function of service condition.

Special ProductsLCM Italia designs and produces also the following valve equip-ment:• Compact Modular ball valves for independent process dual

isolation• Multi-ways ball valves for switching or diverting function.Specialproductsareconfiguredinamodularconstructiontakingadvantages from the engineered trim components available for the basic products.

seals).• Manually operated or actuated for normal operation or emer-

gency function (e.g. MOV, XV, SDV, ESDV, BDV, HIPPS, SSIV).

InstallationsLCMballvalvesmaybeinstalledinthefollowinglocations:• Above ground (from desert to arctic climes, insulated or not).• Underground installation (in pit or directly buried).• On-shoreorOff-shore(top-sideorsubseainstallation&

• METAL to METAL – Seat and ball sliding sealing surfaces are both metallic. Typical hard-facing adopted by LCM is a Tungsten carbide coating obtained through high pressure HVOF process.

Sealing action is obtained by perfect matching of the hard-faced sliding surfaces that are accurately grinded and mate lapped using abrasive compounds.

Sealingperformancesareinfluencedbyseveralfactors(mainlyrelatedtonatureofthetestfluid,applieddifferentialpressureandnominal bore size) and contractually are governed by the applicable product specs and eventual additional customer require-ments.

LCM is able to assure a perfect sealing performance also for Metal to Metal seated ball valves in most of the typical factory acceptance tests.

The valve is also easy maintainable at site, just after removal of from the line, without the need of special tools.

Welded Body cylindrical or spherical bodyLCM welded body ball valves is formerly a side entry construction where the forged pressure containing parts are permanently welded after trim installation.

Due to body construction, the unique maintenance capability foreseen it’s relevant to stem seals and for this reason the valve is normally pro-vided with elastomeric or thermoplastic seating c/w emergency seat sealant injection features.For pipeline applications the valves are normally provided with BW ends and may be completed with pup or transition pieces installed, inspect-ed and tested by LCM before delivery.LCMhasalongoffshoreexperienceforcriticalservicesthatincludescorrosive&sourserviceincludingmetaltometalorpeekseatedapplications.

tmbv - trim configuration

Single or Double Piston EffectSeveraldesignconfigurationswithpolymericseatsealsareavailableintermofseatbehavior:

• Single Piston Effect seat (SPE): assures an unidirectional sealing (as up-stream seat) and guarantee the self-relieving action in case of overpressure into valve body cavity.

• Double Piston Effect seat (DPE): assures a bi-directional sealing action, so may perform a redundant function sealing also as downstream seat (if upstream seat is leaking). In case of overpressure into valve body cavity (e.g. due to liquid thermal expansion) DPE seats will not release overpressure into the line therefore an external automatic release system is normally adopted by agreement with the customer.

LCM standard ball valves are equipped with independent floating seats with single piston effect configuration in order to guarantee the “self-relieving action”, making the valve suitable for most gas, condensing and liquid services.

SINGLE PISTON EFFECT (Self-Relieving - Lower Pressure Side)

DOUBLE PISTON EFFECT (Downstream Sealing - “Trapped Pressure”)

Available Seat Configurations:Bi-directional self-relieving (standard)Double Isolation & Bleed 2 (DIB-2 option)Double Isolation & Bleed 1 (DIB-1 option)

Double Block & Bleed (DB&B as option for all the above configurations)

Standard ball closure members are solid/integral and normally permit depressurization of the body cavity (DB&B = double block & bleed valve feature) when ball is in the closed position and (one or) both the valve conduit are pressurized.

Standard ball are normally provided without equalizing hole to permit body cavity isolation when the line is pressurized and the valve in open position (DB&B-Open), this assure an additional barrier against potential leakage to the atmosphere.

Market demands, project requirements and customer needs are well understood, com-plied with, or anticipated thanks to our engineering structure that is focused on critical applications and under the same department coordinates R&D, application and production engineering.

R&D ActivitiesStrict collaboration with strategic European suppliers of special process and innovative polymeric compounds permit to explore unconventional design solutions.

Oureffortsaredevotedto:

• Increase tightness performance of single and dual isolations.• Improve valve reliability and Reduce fugitive emissions.• Extend chemical compatibility and operating temperature range of polymeric seals.• Enhance quality of overlays and reduce cost of cladded components designated for

extremely aggressive services.• Develop and validate innovative coatings for corrosion protection / metal to metal

seating.

Special Test CapabilityImprovement in performance and reliability are constantly monitored in our special test dedicated area.

ThefollowingtestingcapabilitymaybepartofLCMservices:

• High pressure gas test with nitrogen exceeding 1000 barg.• Low Temperature and cryogenic test down to -196°C.• High Temperature test up over 400°C.• Helium Fugitive Emission tests up to Class A.• Torque tests including long stand still or stall test.• Complete endurance test (DP cycling, LT & HT steps).• Localized hyperbaric tests.• Fire Safe tests.
