Press BrakeHighly accurate positioning,repeatability of machiningcycles, and precisesynchronization control ofcylinders during the closingmovement of the bendingtool, are pre-requisites ofthe hydraulic control system.
Product & System DescriptionBy 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.
BenefitsHigh bending speed, withprecise control of bendingdepth, results in greaterproductivity. The design ofthe safety system blocksreduces production andmaintenance costs.
Injection Molding MachineIt 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 DescriptionVickers 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.
BenefitsReduced 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 enablefeature on the KB line canbe used to easily achieveinterlock function.
SawmillProductivity 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 DescriptionVickers 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.
BenefitsOn-board-Electronics (OBE)valves feature plug and playto save wiring hassle andtuning time. IP 65 & 67environment protectionprovide best in industryprotection 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 PowerWind 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 DescriptionCoupled with LESA servocylinders, Vickers highperformance proportionalvalves KBFDG with CAN Buscommunication capability(developing) and failsafefeature, provide a compact,rugged, and reliable packagesolution.
BenefitsDigital 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.

Valve Performance Level
The application matrix to theright provides a quickvalve sizing approach formany industrial applications.Simply locate your applica-tion (or one very nearly likeit) on the chart, then read offthe Valve Performance 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.

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 BrakeHighly accurate positioning,repeatability of machiningcycles, and precisesynchronization control ofcylinders during the closingmovement of the bendingtool, are pre-requisites ofthe hydraulic control system.
Product & System DescriptionBy 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.
BenefitsHigh bending speed, withprecise control of bendingdepth, results in greaterproductivity. The design ofthe safety system blocksreduces production andmaintenance costs.
Injection Molding MachineIt 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 DescriptionVickers 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.

One valvewith a specially designedspool does all five criticalcontrols of plasticizing,injection speed, holdingpressure, decompression,worm return, and suck-backpressure. The valve enablefeature on the KB line canbe used to easily achieveinterlock function.
SawmillProductivity 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 DescriptionVickers 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.
BenefitsOn-board-Electronics (OBE)valves feature plug and playto save wiring hassle andtuning time. IP 65 & 67environment protectionprovide best in industryprotection 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 PowerWind 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 DescriptionCoupled with LESA servocylinders, Vickers highperformance proportionalvalves KBFDG with CAN Buscommunication capability(developing) and failsafefeature, provide a compact,rugged, and reliable packagesolution.
BenefitsDigital 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.
