KlingerNewsFebruary 2009www.klinger.chThe giant ball valve is hereKLINGER Fluid Control GmbH, AustriaJosef Nahringbauer, MD KLINGER Fluid Control and Dr Thomas Klinger-Lohr, Chairman next to the gigantic KLINGER KHSVI ball valvewith a 1 meter diameter.To meet new demands from the marketplace, the managementof KLINGER Fluid Control has decided to extend its range oflarge-scale valves to include a size of DN 1000 (equaling an internaldiameter of 1000 mm). The ball valve has been developedin the company’s own R&D department using state-of-the-art,three-dimensional tools and computer simulations, especiallyfor use in district heating networks.On 20 November 2008, KLINGER’sfirst ever ball valve of that size waslaunched by Dr Thomas Klinger-Lohr in thepresence of the entire Management Teamof KLINGER Fluid Control GmbH.As an environmentally friendly andcheap energy source district heating has

ecome established in many cities. Due tothe rising energy costs, the scarcity of fossilfuels and the need to reduce CO 2emissionsin line with Kyoto, the expansion ofdistrict heating has been given top priorrity.The continuing expansion of existingTechnical specificationsn Internal diametern Length1000 mm1981 mmn Height with gearbox and actuator 2350 mmn Maximum body diametern Weightn Maximum working overpressure1715 mm9100 kg40 bardistrict heating networks demands largerpipelines and also correspondingly dimensionedshut-off equipment.KLINGER Fluid Control is nowable to meet these demandsManufacture of the first prototypestarted in May 2008 and testing began inthe company’s own laboratory in August2008. In the testing department, the valvewas checked out at maximum loads accordingto a pre-ordained series of tests. Prototypetesting was brought to a succesfulconclusion at the end of October 2008. Aninvestment of more than EUR 200,000 innew gantries, jigs, tools, etc. was requiredbefore manufacture of the new ball valvewas feasible at the Gumpoldskirchen facility.KLINGER Fluid Control, based in Gumpoldskirchen(Vienna), has been a supplier ofspecial high-quality valves for the districtheating industry for more than 30 years.These valves are used not only in Austriabut also in district heating networks forexample in Moscow, St. Petersburg, Parisand Munich. KLINGER valves are knownthroughout the world for their reliability andlong service life. n2KLINGER BALLOSTAR for alternatingtemperature loadsKLINGER Fluid Control GmbH, AustriaAt KF Fluid, our French sales representative, strategy rests ontwo important columns: product differentiation and focus. KFFluid has identified applications such as steam or hot water at160/180 °C where the KVN and BALLOSTAR ranges offer ourcustomers superior tightness during service over a very longperiod of time. But sometimes success comes from unexpectedquarters - and MEG Mono Ethylene Glycol is one of them.MEG is used in many pharmaceuticalprocesses for cooling thermalfluids. The first BALLOSTARKHA SL VIII was installed in 1999 atSANOFI Aramon. MEG fluctuates from– 25 °C to + 150 °C at 10 bars with 1cycle every 8 hours, which is going tobe very tough for any valve.Many valves from differentbrands have previouslybeen installed, but didnot give satisfaction tothe end-user. However,thanks to its 3 pcs design and2 elastic sealing elements the KLINGERBALLOSTAR KHA can handle the changein temperature and stay tight in-line andto the outside. Because of the outstandingquality ofthe KLINGER BALLOS-TAR, the sealing elementsrequire changing every 4– 5 years only. Usually,the end-userwill buy a completebody becauseit is easier than sparesealing elements.New applicationsKLINGER Fluid ControlThe second and very successfulapplications meeting washeld at the Gumpoldskirchnerlocation in October 2008 - akey event that was attendedby our trading partners fromWestern, Central and EasternEurope.

Since 1999, both SANOFI Aramon andSANOFI Sisteron have only been installingBALLOSTAR KHA SL VIII on MEG applications.Other customers successfully usingKHA on MEG are: SOLVAY Tavaux, SOLVAYSalins du midi, FARCHIN, CHARABOT, andORSYMONDE. The next step for KF Fluidis to identify all pharmaceutical plantsthat use MEG in order to repeat the successachieved with SANOFI and otherend-users. nKLINGER technologies on the moveKLINGER Limited, AustraliaKLINGER Limited is proud to be associated with HIsmelt Corporationand their cutting-edge HIsmelt ® process technology.The HIsmelt ® process has beenspecially developed by Rio Tinto to treatiron ore fines with minimal raw materialpreparation using non-coking coals.

A total of 32 tradingpartners from 21 countries took part inwhat has now become a favorite event. Thisyear, too, was an opportunity to tell participantsabout several new applications, makingit very much easier for them to identifynew markets for high-quality KLINGERvalves. KLINGER Fluid Control products arehighly appreciated throughout the world fortheir excellent quality, broad range of applications,long service life and low maintenanceand life cycle costs. In addition tomany new and interesting applications, thehighlight of the event was without doubtthe presentation of the new DN 1000 sizedvalve in our BALLOSTAR range. During a12 bar saturated steam test, participantswere able to see for themselves just howthe new product performs. With a furtherprototype currently «in the pipeline»,series production is scheduled from thebeginning of 2009.Thanks to the great success of theseapplication meetings, we are pleased toannounce that further events are beingplanned for Asia, America and Africa forthe current year. n

KLINGERtop-chem-2000The pressure resistant PTFE material for narrow-section gasketsKLINGER GmbH, Germany4Typical applications can be found inthe plumbing and heating sector, in otherwords with water as the medium and amaximum temperature of approximately86 °C. But threaded unions are alsoused in gas supply. In industrial plant andmachine tool construction, supply linesfor water, nitrogen, oxygen, fuel gas, andalso oil, heating media and coolants, areoften closed off using threaded unions.Threaded unions are also one of the fittingsused for connecting solar collectors,where the temperature of the heattransfer medium can exceed 180 °C, tothe pipe system.Threaded unions with flat gaskets arethus exposed to the most varied media,temperatures and stresses.The Behavior of threaded unionsincorporating flat gasketsTwo different types of threaded union canbe examined:n Connection of a male and a femaleend using a screw-thread connection,where the two sealing surfacesare rotated in opposite directions whenfitting.n Connection of two components withflanged sealing surfaces using a unionnut, with manual resistance eitherreducing or preventing rotation of thesealing surfaces (Fig. 1).A look at the special requirements for achieving a leak-freeseal with narrow-section gaskets - for example in threadedunions - reveals that although these connections have been inuse for many decades, problems are always reoccurring in anumber of application areas.A common feature of both types is theconnection’s relatively rigid behavior. Thiscan best be explained with a contrastingexample - a flange connection (Fig. 2) -where the long bolts and the flange platehave a sprung effect.Fig. 2: Flange connection with spring componentsIn the case of a loss of thickness ofthe gasket (e.g. through heat-relaxation),spring action will result in the maintenanceof some degree of surface pressure- and thus sealing effect and mechanicalstability.With a threaded union, only the pipeor the tensioned section of the union nutcan be regarded as a sprung element,although it’s clear that component lengthsof only a few millimeters are involved.In the illustration (Fig. 3), below it can beseen that the length of the portion undertension merely equates to the thicknessof the gasket plus the flange on the righthandcoupling. The connection surface ofthe union nut can also flex slightly.In practice, the options for compensatinga possible loss of thickness arevery restricted.A further problem with threadedunions is the width of the gasket. Often,the actual sealing width is merely the wallthickness of the component (pipe). Inthis situation, wider gasket rings merelyappear more secure. Moreover, dependingon the component, damage can becaused to the ring gasket during assembly,while rotational movement during assemblycan also lead to considerable shearstresses. And with assembly often beingcarried out using pump pliers, a specifictorque loading cannot be relied on and theresultant forces can varyconsiderably.Fig. 1: Typical screw connectionGasket + Nipple = approx. elastic lengthFig. 3: Elastic component length of a threaded connection

The requirements on thegasket materialThe types of stress described above meanthat special demands are placed on thegasket material. They include:n Low shrinkage, even under temperaturestress, in order to maintain thesealing forces.n Edge stability, despite unfavorable ringwidth (thickness/width ratio)n Resistance to shear or frictionalforces arising from possible relativemotion of the gasket surfaces duringassembly.Additionally:n The gasket material must be ableto conform to the seal counterpart(metal surfaces are standard) sothat no leaks occur on the contactsurfaces.n The sealing material must also beimpermeable, so that this leakageroute is also eliminated.The sealing sequenceIn the case of standard ring gaskets madefrom soft fibrous materials (filler, fibers,elastomer as the binder), the sealing processensues as follows:The gasket is pressed:n It adapts to the surfaces of the sealingcounterpart and seals the contactsurfaces.n In so doing, the cross section of thegasket is placed under mechancalpressure and the existing capillariesand cavities are closed.n This process requires a certain time,however, and is associated with a lossof thickness in the gasket.On first heating, the gasket materialagain becomes slightly softerand resets - with additional loss ofthickness.If, therefore, higher demands are to beplaced on the security of the threadedunion, also from a temperature andduration point of view, standard materialsare no longer able to satisfy thesedemands.The alternativesWhich gaskets can be seen as alternatives,and how are they to be assessed?n Rubber gasket rings - these are veryimpermeable and have an excellentability to adapt; nevertheless, theypossess low stability when faced withhigher demands relating to temperatureand screw forces.n Metal gasket rings - these arevery stable and impermeable, butadapt insufficiently to the sealingsurfaces.n Pure graphite gasket rings - thesehave very high adaptability, but aretoo fragile during assembly and copebadly with the unfavorable thickness/width ratios.n PTFE gasket rings - these exhibit highconformability and are impermeablebut standard materials still possessexcessive flow properties.5Rich. KLINGER Ind e Com Ltda., BrazilKLINGER GmbH lectures at the 15 thInternational Sealing ConferenceKLINGER GmbH took advantage of the 15 th ISC in October 2008 in Stuttgartto showcase their PTFE gasket materials and to lecture on the stabilityof PTFE-material for narrow gaskets. Sales Manager Norbert Weimer, KLIN-GER GmbH, presented the latest results of research and development andthe experiences of applications in practice for KLINGERtop-chem-2000.The prospects for PTFE gaskets aretherefore exrtremely good if the problemsassociated with flow characteristics canbe solved.The following features and measurementswill allow an evaluation of the flowcharacteristics:n Compressibilityn Residual surface pressure on thegasket after temperature cycling

We can create subgroups according tocompressibility:Subgroups according to compressibilityn Compressibility < approx. 3 % High grade PTFE Very suitablen Compressibility approx. 5 –10 % Medium grade PTFE Suitable with conditionsn Compressibility approx. 15 – 30 % Soft PTFE Hardly suitablen Compressibility > approx. 50 % Expanded PTFE Unsuitable6The remaining residual surface pressureafter temperature cycling is a measureof the longterm stability of gasketmaterials. If the gasket material continuesto flow, the residual surface pressurewill be lower.PS10 solar power towerExperience from practicalapplicationsA user of a KLINGERtop-chem-2000high-grade material has run a test to selectthe correct gasket material, and has beengenerous enough to make the resultsavailable to us. This particular applicationwas in the area of chemical pumps.The vent and drain plugs in these pumpsare mostly equipped with narrow ring gaskets(Fig. 4). However, because there is arequirement for the universal use of sealingmaterials in the chemical industry,PTFE is the correct basis.Test structure: non-grooved 120 ×112 mm ring gasket, torque 40 Nm, equivalentto 15.8 N/mm².Test cycle: 5 temperature cyclesfrom 20 – 120 °C over a total of 110 hours.Measurements: thickness of the gasketbefore and after the measuring sequence,and remaining residual torque.The measurement results are summarizedin the following diagrams. Notethat material of equal thicknesses wasnot available. The results have thus beenstandardized to a thickness of 1 mm (linear).The original thicknesses are listedfor information purposes.In the first diagram (Fig. 5) it can beseen that, after the temperature cycles,minimal thickness loss was experiencedon high-grade material only.50,0045,0040,00From the Lossof Torque diagram(Fig. 6) it can beseen that becauseof low loss of thickness during the temperaturecycles, the loss of torque is also atits lowest. Note that the linear standardizationof the results does not correspondto reality, and thinner original thicknessesalways come out with a better evaluation.Because the high-grade material is one ofthe thicker ones, the results can thereforebe seen as especially positive. In reality,for assembly reasons, gaskets between 2mm and 3 mm are mostly used, as in thechemical pump with the threaded plugs(Fig. 7). The significance of the results andthe differences between materials are thusall the more distinct.Ergebnisse Dickenverlust in % / result thickness loss in %nach Einbau normiert auf 1mm Dicke (linear) /after mounting standardised to 1mm thickness (linear)nach Testzyklus normiert auf 1mm Dicke (nur warmverf.) / after testcycle standardused to 1mm thickness (only hot compression)35,0030,00%25,0020,0015,0010,005,000,00Material 1 Material 2 Material 3 Material 4 Material 5 Material 6 Material 7 High-Grade-MaterialMaterial 8 Material 9Fig. 4: Pumps with vent & drain plugsFig. 5: Loss of thickness results70,00Verlust an Drehmoment, normiert auf 1 mm Dicke (linear) /loss of torque, standardised to 1 mm thickness (linear)60,00

KLINGERSIL ® C4265 -a soft solution to a hard problemRich. KLINGER Dichtungstechnik GmbH & CoKG, Austria8A review of the latest documentsissued by law makers and NGOs to dealwith pollution related issues on the technicallevel shows that gaskets are alsoimpacted by the requirements. A verydirect example is when application engineersare asked to provide assistance toa customer and recommend the mosteffective sealing material for a given servicesituation. The demands can be summarizedas follows:n High tightnessn Low bold forcesn Universal chemical resistancen Uneven and/or rough surfacesn Temperatures up to 250°C/500 °FMany sealing applications imposethese requirements, especially in theOEM market. The consultant engineerwill consult the KLINGER Product Catalogueof Gasket Materials in order toidentify a grade that can satisfy the customer’srequirements. A look through thecatalogue will reveal a number of NBRbasedgrades that could meet the specification- with the exception of tightnessat low loads, because these grades showlow compressibility. A further search for agrade with high compressibility will locatean SBR grade. Unfortunately, however, thisgrade is not chemical resistant, and servicetemperature is critical. What now?In order to provide a «missing link»solution, KLINGER Dichtungstechnik hasdeveloped KLINGERSIL ® C4265. This isan NBR-based, synthetic fiber-reinforcedsheeting material designed for use inapplications where superior tightnessat low bolt forces is required. KLINGER-SIL ® C4265’s high compressibility leadsBecause new regulations and directives are increasinglyfocused on pollution prevention, the tightness of joints iscurrently the subject of reappraisal. Application engineersare now confronted more frequently with requirements likeexcellent tightness with low bolt forces and universal chemicalresistance. It is precisely these criteria that apply to many OEMapplications. So far, no KLINGERSIL ® grade has been able tomeet them in full. However, KLINGERSIL ® C4265, the latestdevelopment from KLINGER Dichtungstechnik, has beendesigned specially for such applications. And a comprehensiverange of tests has demonstrated the potential of the new gradeand its unparalleled features.to the excellent surface sealing experiencedwith common SBR materials, butwith the tried-and-tested stress resistanceand chemical compatibility of NBR materials.KLINGERSIL ® C4265 is suitable foruse in liquid and gaseous media such asoils, hydrocarbons, solvents, water, refrigerantsand many other substances attemperatures up to 250 °C/500 °F. Thematerial is dark blue on both sides, with agrayish center.Having now identified KLINGERSIL ® C4265as a suitable material, the applicationengineer will start to check the customer’srequirements against a special set ofproperties:Superior tightness at low boltforces: KLINGERSIL ® C4265 has demonstratedits excellent tightness during testswith fluids, nitrogen and helium. For example,to seal 40 bar of helium at a tightness

of 0.01 mg/m*s, all that’s required is a10 MPa load! What’s more, a tightnessof 0.0000001 mg/m*s can be achievedsimply by increasing the load under thesame conditions. In-house lab tests haveshown that KLINGERSIL ® C4265 complieswith the requirements of the German AirPollution Directive (TA-Luft).The most striking effect of KLINGER-SIL ® C4265’s high compressibility is thematerial’s ability to compensate for unevenfaces even under very low loads, asemphasized and evaluated by a series ofso-called «Out of Flatness Tests».For this test, a gasket is assembledbetween a steel and a glass plate undergasket. ASTM Oil IRM 903, for example,is allowed to impinge under pressure onthe inner diameter of the gasket, and thewhole test fixtures is heated in order tosimulate service conditions. By lookingthrough the glass plate, it is possible toobserve how the gasket creates a sealalong the groove.9Applicable on rough and/or unevensurfaces: It’s widely known thatthe compressibility of a sheeting materialindicates its ability to adjust to criticalsurfaces. The compressibility of standardmaterials varies between 5 and 12 %.Compared with existing state-of-the-artproducts, KLINGERSIL ® C4265 shows acompressibility in the region of 30 %. Thisexceptional property enables the materialto adapt to irregular sealing faces. Acomparison of a Shore Hardness of 40for KLINGERSIL ® C4265 with the averagehardness of approximately 65 for standardgrades underlines the adaptability ofthe new product.a load of 10 MPa. To simulate an unevensealing face on the steel plate, aradial groove with a defined geometry ismilled onto the face in contact with the

Due to its superior flexibilityand compressibility, the material isable to fill the space of the reduced crosssection of the steel plate and prevent leakage.The right-hand test fixture (Fig. 2),on the other hand, has been sealed witha reference material (green), which hasa compressibility of about 10 %.

AES operates 9 power plants with an installed capacity of 2,828 megawatts - or approximately 10 % of the total installed capacityin Argentina. It has two distribution companies, EDELAP and EDES, serving more than 460,000 customers.11A seal of approval from AES AlicuraRich. KLINGER S.A.A.C.I.yF., ArgentinaA problem solved - AES Corporation is one of the world’slargest energy concerns. Operating in 29 countries and on 5continents, AES generating plants and distribution companiessupply energy to 100 million people. In 2007, sales topped USD13,600 million.At the beginning of 2006, Rich.KLINGER Argentina received an enquiryfrom AES Alicura regarding a fault withJIS standard spiral wound gaskets (in AISI316 stainless steel with graphite filler) suppliedby competitors. These gaskets werecausing a leak in the refrigeration duct ofa Mitsubishi 701 gas turbine, where airwas at 460 °C and 16 bars. Replacementof the damaged gasket required the gasturbine to be taken out of service and thewhole operation took approximately 10hours. Normal operations require regularshutdowns and start-ups with correspondingexpansion and contraction inthe pipes. The faulty gasket showed afracture on the centering ring as well asdistortion on the spiral-wound body. DrTeodorico Lythgoe, Technical Director atRich. KLINGER Argentina, and Mark Williamsof KLINGER Ltd, UK, concluded thatbecause of the high temperatures of thisapplication, gaskets with KLINGER MaxiflexZonal mica/graphite/mica filler shouldbe used. Spiral-wound gaskets with micaand graphite offer excellent resistance tohigh temperature applications. The micaacts as a barrier and insulates the graphiteagainst possible oxidation. ”We havebeen using this type of gasket since 2006without air leakage”, say maintenance personnelat AES Alicura, and thus give KLIN-GER their seal of approval! During the lastplant shutdown, AES replaced the set ofKLINGER gaskets as a scheduled maintenancemeasure. After 8000 hours of use,the company was able to confirm theirperfect condition. Ten turbine shutdownsand start-ups were scheduled during thisperiod, each accompanied by the risk ofa leak, but the KLINGER Maxizonal mica/graphite/mica gaskets stood up to theconditions easily, safely and reliably.AES ArgentinaWith capital expenditure exceedingUSD 1 billion since it started its operationsin 1993, AES Argentina is one ofthe three main investors in the electricitysector in Argentina and the largest fromthe United States.AES AlicuraThe Alicura Dam is the first of fivedams on the Limay River in the northwestof the Comahue region on the borderbetween the provinces of Neuquenand Rio Negro, Argentina.

Small is the new bigRich. KLINGER Ind e Com Ltda, BrazilThe new compact actuated control valve is lighter, easier toinstall, and consumes less compressed air.12The Brazilian market already knowsthat Richard KLINGER offers technicallyadvanced products that come with realreductions in operating costs for the generationand distribution of steam, compressedair and other industrial fluids.Until now, KLINGER has supplied themarket with an actuated control valve thatthanks to its high durability and reliability,has achieved considerable success. Withthousands of units installed all over theworld, this valve is recognized by users asa design that combines outstanding performance,the safety of a globe valve witha piston sealing system, and the efficiencyof an actuator using a pneumatic springand no diaphragm.Now, KLINGER is extending its productline by offering a new compact actuatedglobe control valve. This is the secondgeneration of a product with qualitiesthat are already acknowledged by the market.It comes with additional advantagesfor industrial control operations, includingthe control of termperature, pressure,flow and level.Manufactured entirely in injectionmoldedaluminium, this new actuator isfar lighter and smaller, making it easierto install and handle and facilitating thedesign of the piping.Despite its compact size (approximately40 % less than the previousKLINGER actuator), the new KVA actuatorretains the classic advantage of allKLINGER actuators: it uses a maintenance-free,pneumatic spring in place ofa diaphragm.This actuator allows the new KLIN-GER control valve to carry out on/off controloperations in diameters of ½” to 2” andat pressures of 0 to 40 bar with almostany type of fluid. This means that a singleactuator can be used for the three sizesThe very latest in actuatortechnologyAlways attuned to the needs ofthe industry, KLINGER has developed asmaller product that will help its customersdecrease the time and cost of installation,operation and maintenance. That’sbecause the KLINGER compact controlvalve introduces a new concept in controlvalves. Its main feature is the new,surprisingly compact, light and modernKVA actuator.New compact actuated control valve: small, light, attuned to the needs of the industry.Principal advantages of the new valve:n Light and super-compact actuatorn A single actuator for dimensions between ½” and 2”n Faster response and lower consumption of compressed airn Class VI leakage level for temperatures up to 400 °Cn Easier to install, operate and maintain

Sustainabilityn The compact KLINGER valve supports the new concept of preventinglosses and decreasing emissions of pollutants into the atmosphere.of actuator previously used in the ½” and2” range. In other words, the actuator ona DN 50 valve can also be used on a DN15, thus simplifying stocking.Previous actuator and the new KVA model:a 30 to 50 % decrease in dimensions.Food companies, textile companies,machine-tool manufacturers and sugar/alcohol refineries are among the usersthat have already installed the new compactKLINGER control valve. Like its predecessor(which is still available in diametersbetween 2 ½” and 8”), the new compactKLINGER valve can be used in liquids, gassesand steam. On/off and control functions(flow rate, pressure and temperature)are combined in the same valve.Surprising dimensionspromote savingsThe innovative design of the compactKLINGER valve can best be appreciatedwhen compared with the previousmodel for applications with diametersbetween ½” and 2”. The weight hasbeen decreased from 18 kg to approximately5 kg. There’s also an impressivedrop in size: the height of the new actuatoris down by 30 %, while the diameteris down approximately 50 % (an especiallyimportant factor for machine-tooland equipment manufacturers).Thanks to the new dimensions,response times are faster and compressedair consumption is also improved: with thenew 2” compact valve, for example, it ispossible to reduce compressed air consumptionby more than 90 %. But that’snot all: installation and maintenance aremuch faster - with the quick connectionsystem enabling rapid assembly and dismantling- and because the actuator isnow much lighter, lifting tackle is a thingof the past. Furthermore, the positioningcomponent is now installed directly onthe actuator, thus eliminating the needfor adaptors or fittings. n13Reliable for industry, safe for the environmentThe KXGT graphite seals employedin the compact KLINGER valve guaranteethat the unit has Class VI leakage.As a key KLINGER feature, KXGT graphiteseals prevent the emission of chemicalsinto the atmosphere and the subsequentloss of valuable and/or corrosivefluids for users.KXGT graphite seals also meangreater energy efficiency, with lesssteam loss, less waste, and less consumptionof fuels such as natural gasand oil. Because the contact is metalgraphiterather than metal-metal, the«soft» technology of the graphite ringsguarantees a 100 % seal.A further advantage of the compactKLINGER valve is that its lanternsare specially dimensioned to suit eachapplication in order to control the glowcoefficient in line with each process.Another key feature of the newproduct is the quick connection systemthat enables the valve and actuatorto be separated for maintenance ofthe two components (valve and actuator).Moreover, in conventional valves,depending on the working pressure, itmay be necessary to open the actuatorand replace the springs. But thecompact KLINGER valve functions wellbetween 0 and 40 bar, with no need toreplace the springs.With a body assembled from highstrength materials (carbon steel or stainlesssteel), the compact KLINGER controlvalve is ideal for incorporation intonew line layouts or the replacement ofvalves that have reached the end oftheir service life. Once again, KLINGERhas launched yet another product thatmeets the company’s standards in full:namely, high quality and high strength,in addition to the Class VI leakagealready mentioned. nTo find out more about this compactvalve, phone (11) 4596-9514, ore-mail: rkvendas@rklinger.com.br.
