IDEAL FOR VALVE manifoldsDSV COMPLETEPentair Südmo valve manifolds- Our Know-How, your successPLANNING, DESIGN & PRODUCTIONCUSTOMER BENEFITSA successful process begins with thedesign and assembly of the valves intolarger function units. As well as the purefunctionality of the system, many otherpoints must be taken into account:• Selection of suitable components• Correct installation position of allindividual components• Arrangement with no dead zones• No sumps or domes• Complete drainability• Arrangement compatible with orbitalwelding• Reduction in number of weld seams• Compensation for heat expansion• Adequate support and stabilisation ofcomponents• Capture and discharge of leakage• Simple maintenance work3D drawing of a valve manifoldBefore production comes planning. Usingmodern 3D systems, the valve manifoldis planned in every detail and the resultpresented to the customer. Then productionof the valve manifold can begin.Building the frameA stainless steel tube frame holds the valvemanifold. Each frame is made individuallyto meet the customer's needs.Mounting the valvesThe individual parts of the valves formounting come together on the workbench.The valve housing is sent directly to theplant construction.Housing preparationBefore combining the valve housings into amanifold, the housings are equipped withflanges, elbows and other componentsusing welding machines.Orbital weldingThe valve housing is welded using orbitalwelders. Together with accurate weld seampreparation, this ensures reproducible weldseams of the highest quality.PreparationAll weld seams of the valve manifold areexternally prepared mechanically. The valvemanifold is then cleaned.Fitting valve upper partsFinally, the valve manifold is fitted with thevalve upper parts, the air hoses suitableto the customer's needs, and the electricwiring for the process control heads isprepared; the finished valve manifold isthen subjected to a final test.Finished valve manifoldsThe finished valve manifolds can beinstalled in your plant directly afterdelivery and brought into operation.• Cost-efficient complete package• Decades of experience in design andproduction• Compact construction• Simple and rapid installation• Perfect integration in process control(e.g. IntelliTop2.0 with 24VDC, ASinterface, DeviceNet, or 110VAC)• Countless possible variations inconsultation with our experts• Simple access for maintenance(e.g. with access platforms or steps)• Excellent WIG weld seam qualities toDIN EN 287• Valve manifold production observingPressure Vessel Directive 97/23/EC14

Intelligent Control TechnologyINTELLITOP ® 2.0The innovative controlunit offers the customercountless possibilitiesfor automation ofprocess systems, andhence considerablepotential for increasingefficiency.The IntelliTop 2.0 was awarded the IFProduct Design Award 2010 for its perfectcombination of function and aesthetics.The IntelliTop 2.0 control unit from PentairSüdmo combines control and monitoringof process valves in one unit. The decentralarrangement of the control heads on theprocess valves allows a reduction in hoseand cable lengths and leads to a clearsystem structure.The heart of the IntelliTop 2.0 is the travelmeasurement system to detect up to threeswitch positions of the process valve. Greatemphasis has been placed on simpleprogramming by means of three Teach-Inkeys. This guarantees rapid and processreliablecommissioning. At the same time,the closed travel measurement systemserves as a protective tube which preventsrisk of injury when the control head is open,and protects the internal technology oninstallation of the head.BENEFITSCommunication24 V DCAS interfaceDeviceNet110 V ACTravel Measurement SystemLift range 85 mmFeedback 3 positions, adjustable,connection for externalsignalMagnetic valvesNumberFlowChoke function0-3 pcs200 l/minIntake and extraction airseparateElectrical connections24 VDC Cable passageAS interface Cable with 4-pin M12x1plugDeviceNet Cable with 5-pin M12x1plug110 V AC Cable passagePneumatic connectionsPush-fit hose connection Ø 6 mm(optional 5/16“)Push-fit hose connection Ø 8 mm (1/4“)Other dataLED status display green, yellow, redProtection classes IP65 and IP 67 combinedIP 69KEx-zone Zone 2/22Technical Data BENEFITS• Process-reliable system monitoring,simple, intuitive and rapidimplementation• Process valve switch times can be setusing integral supply and extraction airchokes• All-round LED display for visual statusmonitoring (colour allocation can beconfigured)• Simplified valve maintenance thanksto maintenance function which can beactivated externally• Plant-specific adaptations via integratedmicrocontroller• Integrated microcontroller suppliesadditional information• Short air hose and cable routes, clearstructure of process plant• Simple, rapid fault analysis and repair, soreduction in plant downtimes• Compact construction and optimumcompatibility with Pentair Südmo processvalves• Scanning of all valve positions possible indouble-seat valveDSV COMPLETE double seat valves15
