Enabling Creative Solutions

Designed for BetterPerformance

Previous models of Vickersproportional valves featuredcontrol amplifiers built andpre-wired directly onto thevalves for simple installation.Integration of the twoproduces a product that canbe cost effective overprevious models.The KB proportional valvetakes the electronicsintegration concept a stepfurther, by placing externalelectronics wiring inside thevalve. This makes Vickers KBproportional valves lesssusceptible to failure.

Integrated AmplifiersMean “Plug and Play”

Integrated amplifiers arefactory preset and eliminateany adjustment of gain,deadband compensation, ordither required for separatecard and valve combinations.Plus they eliminate the needfor field adjustments andseparately wired andmounted cardholders.Replacement valves can befitted without adjusting orchanging the control signals.

New Design Means New Applications

With Vickers KB proportionalvalves, design engineersnow have a viable newcontrol package that they’venever had before...a newgeneration of integratedvalves that redefine andexpand industrial applicationdesign capabilities. Vickers proportional valvesare much easier tounderstand and install thanprevious models usingseparate drive amplifiers. Theonly electrical inputs requiredare a power supply and avoltage command signal.

Built to Last

For durability, you can’t beata KB proportional valve. Theamplifier is housed in adurable metal enclosure,sealed against environmentalcontaminates such as cuttingfluid spray, direct, water andfluid wash down. Seven-pinelectrical mating connectorsare supplied as standard.They are reliable, rugged andprovide easy access for testequipment.Consistency of quality isassured with the KBproportional valve. Eachvalve/amplifier combinationis tested and calibrated as atotal assembly with avariation of less than 5%from valve to valve.You can trust Vickers KBproportional valves to do thejob as specified and performconsistently and reliably for years.

As technology continues to improve, so does theengineering Eaton builds into its proportional valves.Vickers KB proportional valves are a good example ofEaton continued commitment to designing andmanufacturing market-leading products. Vickers KBproportional valves are manufactured, backed andsold throughout the world with the high quality youexpect from Eaton.

Valve Performance Level The application matrix to theright provides a “quick”guidance for many industrialapplications. Simply locateyour application (or one verynearly like it) on the chart,then read off the ValvePerformance Level(Standard, High, or ServoPerformance) at the top andthe ISO Valve Size (Size 3, 5,7, 8 or 10) on the right side.For example:

What size valve and what performance levelshould I choose for my Sawmill Setworks?

Sawmill Setworks applications generallyrequire Servo Performance type valves. Thevalve size could be either a Size 5 or a Size7 depending upon the flow requirements ofthe application.

The matrix uses “FrequencyResponse” as the primarydeterminant for valve per-formance. This is not the onlyparameter of importance in allapplications, but it does serveas a good first reference.

Press Brake

Highly accurate positioning,repeatability of machiningcycles, and precisesynchronization control ofcylinders during the closingmovement of the bendingtool, are pre-requisites ofthe hydraulic control system.

Product & System Description

By using two K(B)F/SDG4Vproportional valves for small-tonnage machines, or twoK(B)HDG5V valves for large-tonnage machines in closedloops, Vickers valves providethe solution to this verydemanding application.System control blocksprovide full compliance tosafety regulations.

Benefits

High bending speed, withprecise control of bendingdepth, results in greaterproductivity. The design ofthe safety system blocksreduces production andmaintenance costs.

Injection Molding Machine

It is critical that theplasticizing process beprecisely controlled, whichrequires accurate, repeatable,and smooth transition fromvelocity into pressureregulation. It is also imperativeto achieve smooth, quick, andprecise clamping movement,in order to improve productivityand quality.

Product & System Description

Vickers Servo performanceproportional valves K(B)S/HDG and high performanceK(B)FDG families withtailored spool design, are theanswers for meeting theextremely demandinginjection and clamping controlrequirements, with theexcellent dynamic capabilityof closed loop control onpressure, position, and velocity.

Benefits

Reduced cycle time andcosts, with improvedprocess control. One valvewith a specially designedspool does all five criticalcontrols of plasticizing,injection speed, holdingpressure, decompression,worm return, and suck-backpressure. The “valve enable”feature on the KB line canbe used to easily achieveinterlock function.

Sawmill

Productivity is king, whichtransforms to therequirements of overallmachine reliability anddurability, and precise control,and short cycle time. Harshenvironment is anotherchallenge for proportionalvalves mounted on themachines; robustness againstshock, vibration, EMC, dirt,and moisture is a must.

Product & System Description

Vickers Servo performanceproportional valves KBS/HDGwith fully encapsulated OBE(EN90 version) provideextremely reliable protectionin condition of vibrations andshock. Valves with zero lapspool and groundedspool/sleeve pilot stage arecharacterized by their high-dynamic performance, withlow hysteresis and highresponse sensitivity, toachieve accurate positioningcontrol and speed control.

Benefits

On-board-Electronics (OBE)valves feature “plug and play”to save wiring hassle andtuning time. IP 65 & 67environment protectionprovide “best in industry”protection against moistureto make sure theproportional valves workreliably. When coupled witha Vickers LESA servocylinder, the proportionalvalves can be mounteddirectly onto the cylinder tobecome a servo actuatorpackage.

Wind Power

Wind power turbine control isa very demanding applicationthat requires proportionalvalves to be extremelyreliable and durable due tothe nature of continuousproduction process. At theheart of advanced windturbines is a hydraulic controlsystem that controls the pitchangle of the turbine blades,hence controlling the speedand power production.Challenges are closed looppositioning control for precisepitch angle, and low and highambient temperatures inextremely harsh environments.

Product & System Description

Coupled with LESA servocylinders, Vickers highperformance proportionalvalves KBFDG with CAN Buscommunication capability(developing) and failsafefeature, provide a compact,rugged, and reliable packagesolution.

Benefits

Digital On-board-Electronics(OBE) valves featurepresetting the parameterswith programming, whichresults better reproducibilityand repeatability; it alsoallows you to fine tune anddiagnose the valves remotelythrough CAN bus. Failsafefeature prevents theequipment from beingdamaged. IP 65 and 67protection ratings meanVickers valves provide betterresistance to moisture thanany competitors.
