MOOG穆格公司成立于五十多年前，Z初从事飞机与部件的设计及供应。如今，本公司的运动控制技术广泛应用于民用机座舱、发电风机、一级方程式赛车、医用输液系统等众多的市场和应用领域，有效提高相关产品的性能。该公司历史起源于公司创建者威廉C穆格，他是一位发明家、企业家，也是一位远见卓识者。1951年，比尔穆格研制成功电液伺服阀，这种装置可把微弱的电脉冲转换为极ng确而有力的运动。1951年7月，比尔穆格、阿特兄弟俩和卢盖耶在纽约州东奥罗拉租借了已废弃的Proner机场的一角，成立了穆格制阀公司（MOOGValveCompany）。穆格MOOG公司是设计，制造和精密运动控制产品和系统集成商。穆格的高性能系统的控制和商用飞机，卫星和航天器，运载火箭，，工业机械，风能，海洋应用和YL设备.MOOG分类MOOG阀，MOOG伺服阀、MOOG伺服电机、MOOG控制器、MOOG伺服驱动器，MOOG电液伺服阀，MOOG柱塞泵穆格的首批订单**份订单是来自BendixAviation公司的制造四个阀门的订单。随后是来自波音公司和Convair公司的较大订单。伺服阀给航天航空业带来了一场变革，并促成了穆格公司（MoogInc.）的建立。到了1954年，穆格公司的阀门已成为美国半数以上歼击机和超过70%上使用的标准设备。公司还成功推出了工业阀门，到了1960年，总销售额已增长至一千多万美元。在本公司Z自豪的航天航空领域，我们的工程师设计并制造了土星C-5火箭的作动器，正是该型火箭于1969年7月将尼尔阿姆斯特朗送上了太空，在月球上迈出了历史性的**步。20世纪70年代至90年代：持续增长20世纪70年代，本公司进入了成长中的注塑与吹塑成形工艺控制技术市场。由于公司较多地参与了美国的太空计划，因此赢得了航天飞机硬件供货合同。航天飞机于1981年首飞，首次应用了本公司开创性的电传控制技术。1988年，本公司飞机部门总裁RobertT.Brady被任命为首席执行官。1989年的销售额达到了2.82亿美元。本公司于上世纪90年代中期在印度建立了业务。我们的首次大规模收购是从AlliedSignal公司购买了后者位于加利福尼亚州托兰斯的飞机业务。到1999年底，公司收入超过了6.30亿美元。Z近的成功案例2001年，本公司获得了一份五千万美元的航天飞机翻新合同，并且公司股票从美国证交所转到了纽约证交所。我们是洛克希德公司生产的F-35型战机的飞行控制系统指定设计商及供应商，并且是波音公司787“梦想飞机“计划主要飞行控制部件的提供商。2004年，公司收入突破9亿美元大关，完成了又一次大规模并购，收购了LittonPoly-Scientific公司，并将其命名为穆格部件集团（MoogComponentsGroup）。公司财年销售额首次突破10亿美元。穆格：创新的环境比尔穆格的创新感远不限于产品设计。他从一开始就坚信工作场所应该是一个很特殊的地方。他相信：人们在一个得到信任、尊重和回报的工作环境中，会更有创造力、更专注、更有工作效率。这一套思想就是日后人们熟知的“穆格理念”。这套原则即便在今天也在引领着本公司前进。“在一个彼此信任、彼此有信心的氛围中，工作对于所有人都会是一种回报更多、更令人满足的体验。”BobBrady在公司的《2006年报》中写道：“本公司Z重要的属性就是公司文化，它将我们的人员团结起来，并为他们提供了动力。这种文化基于正直、诚信和互信。它重视工作能力、非凡的努力、个人责任、协作关系和开放式沟通。正是它把Zyou秀的人才吸引并留在本公司。在这种环境中，他们可以做出**的工作成绩。了解本公司人员的客户都知道：他们将竭尽全力履行本公司的承诺。倘若穆格公司的一位员工做出了一项许诺，那么公司将信守许诺。”本公司从始至终深信：只有当人们在一个环境中感到自己受重视，有充分的参与机会，并且被赋予履行职责的权利时，他们才会有**工作表现。而其它公司才刚刚发现这点。正如比尔穆格曾说：“我们相信在这里工作的人们……我们知道的**可行方式就是让人们彼此信任并充满信心。”作为一个十分成功的企业，穆格的基石是一群努力工作、才华出众、富有奉献精神的人员。1997年秋季，比尔穆格与世长辞。本公司董事长兼首席执行官BobBrady在比尔去世后不久所致的追悼辞中，对本公司做了如下描述：ServovalveswithintegratedElectronicsD791andD792Series23Q[l/min]=max.flowΔp[bar]=valvepressuredropwithQAK[cm2]=spooldriveareapX[bar]=pilotpressureThepilotpressurepXhastobeatleast15barabovethereturnpressureofthepilotstage.D791andD792SeriesThreestageservovalvesPrincipleofoperationAnelectricalcommandsignal（setpoint,inputsignal）isappliedtotheintegratedcontrolamplifierwhichdrivesacurrentthroughthepilotvalvecoils.Thepilotvalveproducesdifferentialpressureinitscontrolports.Thispressuredifferenceresultsinapilotflowwhichcausesmainspooldisplacement.Thepositiontransducerwhichisexcitedviaanoscillatormeasuresthepositionofthemainspool（actualvalue,positionvoltage）.Thissignalthenisdemodulatedandfedbacktothecontrolamplifierwhereitiscomparedwiththecommandsignal.Thecontrolamplifierdrivesthepilotvalveuntiltheerrorbetweencommandsignalandfeedbacksignaliszero.Thus,thepositionofthemainspoolisproportionaltotheelectricalcommandsignal.QQppNN=ΔΔp2,510QAXp-2K≥ΔTheactualflowdependsontheelectricalcommandsignalandthevalvepressuredrop,andmaybecalculatedusingthesquarerootfunctionforasharp-edgedorifice.TheflowvalueQcalculatedinthisway首ldnotexceedanaverageflowvelocityof30m/sinportsP,A,BandT.Q[l/min]=calculatedflowQN[l/min]=ratedflowΔp[bar]=actualvalvepressuredropΔpN[bar]=ratedvalvepressuredropOperationalfeatures?Electricalpositionfeedbackwithpressureisolatedpositiontransducer（LVDT）,nowear?IntegratedSMDelectronicswithfalsepolarityprotection?Optionalexternalpilotsupplyandreturnconnectionsviafifthandsixthportinvalvebody?Lowthresholdandhysteresis,excellentnullstability?Preadjustedatfactory4Iflargeflowrateswithhighvalvepressuredropsarerequired,anappropriatehigherpilotpressurehastobechosentoovercometheflowforces.Anapproximatevaluecanbecalculatedasfollows:ThevalvesD791andD792SeriesdescribedinthiscataloguehavesuccessfullypassedEMCtestsrequiredbyECDirective.Pleasetakenoticeoftherespectivereferencesintheelectronicssection.OurqualitymanagementsystemiscertifiedinaccordancewithDINENISO9001.Thiscatalogueisforuserswithtechnicalknowledge.Toensurethatallnecessarycharacteristicsforfunctionandsafetyofthesystemaregiven,theuserhastocheckthesuitabilityoftheproductsdescribedhere.IncaseofdoubtpleasecontactMoog.TheflowcontrolservovalvesD791andD792Seriesarethrottlevalvesfor3-wayandpreferably4-wayapplications.Thesethreestageservovalveshavebeenespeciallydevelopedforsuchdemandingapplicationswherehighflowratesandatthesametimeextremedynamicperformancerequirementsmustbemet.ThedesignofthesevalvesisbasedonthewellknownD079Series.TheintegratedelectronicshasbeenreplacedbyanewdesignapplyingSMDtechnology.ThevalvesareofferedwithpilotvalvesofD761orD765Series,optionalstandardresponseorhighresponseversionsareavailable.SeriesD791candeliverratedflowupto250l/min,SeriesD792isavailablewithratedflowupto1000l/min.Thesevalvesaresuitableforpressureorforcecontrol,positionandvelocitycontrolsystemswithhighdynamicresponserequirements.D791andD792SeriesGeneraltechnicaldataOperatingpressurerangeMainstagePortsP,AandBwithXinternalupto315barwithXexternalupto350barPortTwithYinternalupto210barPortTwithYexternalupto350barPilotvalvePortsP,AandBD761,D765Seriesupto315barPortTupto210barTemperaturerangeAmbient-20to+60°CFluid-20to+80°CSealmaterialFPM,o
