• SOFT SEATED - Perfect sealing is assured by a polymeric seat (or seat insert).

• 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.

APPLICATIONS


trunnion mounted ball valvesAPI-6D Trunnion mounted ball valves are designed according to ASME VIII / B31.3. - ASME B16.34 are available upon request.

Side Entry - 2 or 3 pieces - Bolted BodyBody is forged or casted.

Sideentryconstructionisthemostsimpleanreliabledesignconfigurationduetothefollowingaspects:

• Closure member vs. seat and relevant connection of pressure containing parts are axial symmetric and self-aligning.• Energizingofseatsealandstaticsealofflangedconnectionisachievedbytheassemblyoperationofthevalve.• Threepiecessymmetricconstructionit’smodularandmayguaranteeaflexibleconfiguration.

Thefollowingalternativesmaybeobtainedjustreplacingthetwoendsclosures:• Full or reduced bores.• All types of end connection.• Seatconfigurationandrelevantfeatures.

• Twopiecebodygenerallyprovidethefollowingbenefits:• Weigh reduction (especially when cast body is applied)• Reduced potential leak path

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. SAW of pressure containing parts is always a narrow gap type and is 100% volumetrically inspected with UT.

Thisconfigurationofferthefollowingbenefits:• Weightisreduced(comparedtoboltedconfiguration).• External leak path are minimized.• Structural integrity is enhanced.

Thisconfigurationistypicallyadoptedwhennomaintenanceisforeseen,typicalapplicationsare:• Underground installations.• Gas transmission lines (L-XL-XXL sizes with DPE seats).• Offshoreandnon-criticalSubsea.

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.

Top Entry - Cast Body - “Forged special applications”Top entry construction permits the installation and removal of trim components from top bolted cover.

Forged body is available for small sizes, high pressure applications, extremely corrosive (e.g. CRA cladded wetted parts) or wherever the supe-riorintegrityoffinegrainstructureisadvisable.

Topermittheinstallationoftheballfromthetop,seatarrangementsmayclassifiedintwomaincategories:• Split seat types (seating element is installed with the ball)• Push back types (seat arrangement axially retract and it’s locked after return to the energized seating condition)

Maintenance of valve internal components is possible without removing the valve from the line.Special tools are required to perform trim maintenance of push back types and may be quoted upon request.

Top entry valve may be supplied with all types of end connections, BW is selected high integrity lines, HUB ends are recommended for HP forgedconfiguration.

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”)

TMBV Working PrincipleClosurememberisasphericalshapedcomponent(ball)withacylindricalflowpassage.BallisTrunnionsupportedonwhichmayrotateopeningandclosingtheflowconduit.Trunnions may be integral with the ball (typically medium size and larger) or may be separate components for small valves.Ball smooth rotation is assured by self-lubricated sliding bearings that assure a long service life without need of lubrication.

TMBVareequippedwithtwoindependentfloatingseatsthatguaranteeatightbidirec-tional sealing with reduced seat wear and low operating torque.Seating is assured by a dual mechanism; springs energize the contact against the ball andguaranteeagoodsealingactionatlowerdifferentialpressure,whilewhendifferen-tialpressureincreaseacrosstheseat,pressureassistedsealingaction(pistoneffect)become predominant and assure a tight sealing within the entire valve rating.

Low operating toques and controlled load/wear of the seat/ball contact pressure make thistrimconfigurationidealformediumandlargesizes,highpressureapplicationsandfor or every actuated function.


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.

The above-mentioned features (DB&B and DB&B in Open position) are intrinsically included for LCM soft-seated ball valves equipped with polymericseals,butifrequiredshouldbealwaysspecifiedinordertoconfigureasafeandappropriatebleedingconnectiontoventthebodycavity and verify this functionality during FAT.

For M & HP pressure valves equipped with metal to metal seating or the hardest grades of thermoplastic seat inserts (PEEK and PCTFE) DBB capability may be limited at 85% of pressure rating as function of trim material selection required/offered.In the above mentioned cases, when fully rated DBB or “independent” double isolation and bleed (DIB) valve are required LCM may offer alter-native trim material selection or oversize trim components optimizing the sealing performance & reliability using FEA approach.
