PROCESS CONTROL IMPROVEMENTEngineered to the High PerformanceStandards of Today’s SophisticatedControl Instrumentationreal performance improvements will only berealized if the final control element is up tothe task. Frequently, the inconsistent andsluggish performance of pneumatic actuatorsor the unreliability of typical electric actuatorsis the limiting factor in the performance of thecontrol loop. Therefore, when it is necessaryto improve process control performance, thefirst step is to improve final control elementperformance.To fully utilize the power and performancecapabilities of today’s process controlinstrumentation, the final control elementmust be positioned quickly, precisely andconsistently. Beck electric actuators provideinstantaneous response with the precision andrepeatability necessary to fully utilize controlsystem capabilities.Beck actuators maximize final controlelement performance, providing responsive,repeatable actuation. Beck's unique design—incorporating a no-burnout motor, efficient spurgearing and accurate, durable electronics—enables the Beck actuator to start and stopinstantly, virtually eliminating dead time andovershoot regardless of load or processconditions.As the emphasis in industry continuesto focus on improved quality and efficiency,and as environmental pressures continue toexpand, the need for improved process controlperformance will also continue to broaden.Industry will continue to make large capitalinvestments in state-of-the-art instrumentationand advanced control technologies.

More Consistent and Precise thanPneumaticsMore Reliable than Conventional ElectricActuatorsBeck actuators eliminate the performancebottlenecks created by inconsistent andnonlinear pneumatic actuator performance,which typically varies as a function of frictionaland dynamic load, process conditions, thecondition of the valve or damper and theperformance of actuator accessories such asI/P transducers, regulators and positioners.Unlike pneumatic actuators, Beck actuatorsprovide consistent and repeatable positioning.Beck actuators incorporate a no-burnoutmotor, an efficient spur gear drive trainand accurate, durable electronics. Thisunique design eliminates the performancelimitations typical of electric actuators,including overheating motors, trips, worm gearwear-induced backlash, coasting and otherpositioning inaccuracies.Beck-built motors are specifically designedto provide instant acceleration and decelerationfor extremely precise positioning in modulatingapplications. These reliable motors do not burnout or overheat even under the demandingconditions of an active control loop.Figure 1-1 shows the response of apneumatic diaphragm valve actuator to a2% ramping demand signal representativeof a control signal modulating the valve. Theresponse demonstrates actuator dead timeand overshoot often referred to as “stick andslip.” It is not unusual for stick to completelyprevent actuator response to the small demandchanges typical of continuous process control.Figure 1-3 illustrates the cool, stableoperation of the Beck motor in comparison withconventional single-phase and three-phasemotors. Tests were conducted under a 100%duty cycle to simulate maximum control loopactivity. The temperature in the conventionalmotors quickly rose to a dangerous level,tripping the thermal overloads, rendering themotor unavailable for control.Figure 1-2 shows the response of a Beckelectric actuator to the same demand. TheBeck actuator tracks the demand closely,eliminating dead time and the significantovershoot associated with the pneumaticactuator. This type of performance gain in theactuator could be the difference between anuncontrollable flow loop and a tightly controlledone.Motor Temperature RiseActive Control Loop120110100Temperature ( C)Throughout this brochure, the phrase“continuous operation” refers to the actuator’sability to operate continuously when requiredfor accurate process control, especially duringstart-up, load changes and process upsets.However, excessive modulation due to processnoise, electrical control signal noise, or controlsignal aliasing will shorten the life of theactuator as well as the valve or damper. Forthis reason, the control loop should be properlyanalyzed and tuned to avoid excessive orunwarranted modulation.The Beck motor, in contrast, slowly rose intemperature under these service conditions,remaining stable and continuously availablefor process control.Conventional Motor - Abrupt Loss of 06050020406080100120140160180Time (minutes)Figure 1-3Cool, stable operation of the Beckcontrol motor9

GROUP 11DAMPER & QUARTER-TURN VALVE ACTUATORSAccurate, dependable control for a wide variety of applications.Beck Group 11 electric actuators provideprecise, consistent modulation of all types andsizes of dampers and valves. Unlike traditionalelectric actuators, Beck actuators have no dutycycle limitation and can continuously modulatewithout overheating.Beck actuators have the unique abilityto quickly, accurately and consistently trackthe control signal. This ability significantlydecreases process variability—improvingproduct quality and reducing operating costs.Beck has eliminated the problems associatedwith pneumatic actuators such as stick-slipresponse, inconsistent performance and airquality issues. Virtually maintenance-free anddesigned for harsh industrial environments,Beck will drastically reduce your maintenancecosts while improving your process control.Beck Group 11 damper drives are equippedwith a specially engineered crank arm. Customlinkage arrangements are available.Beck Group 11 valve actuators areengineered for direct-coupling on quarter-turnball, plug and butterfly valves. They may alsobe installed using specially engineered crankarm and linkage arrangements.Valves and actuators may be orderedtogether as pre-engineered assemblies readyfor drop-in installation; or actuators can besupplied separately along with the necessaryhardware for field installation on existingvalves.11

This saves time duringinstallation and troubleshooting, allowing onlineadjustments to be made quickly and easily bybypassing the electronics in the actuator andcontrol system.The Handswitch also serves as an electricalbackup in the event of control system failure.WiringTerminalBlockAuxiliary and Over-travel Limit SwitchesTwo over-travel protection limit switchesare provided. Up to four auxiliary switches areavailable. Optional switch features: SPDT switches rated for a minimum of 6 A at120 Vac, (three times maximum motor currentfor most models) to ensure long life. Field-adjustable to operate at any point in theactuator’s travel range. May initiate secondary functions or provideremote indication of actuator position.Group 11 Components12 Eliminates unreliable and maintenanceintensive proximity switches.
Drive TrainPower and Durability to Maximize ControlAvailabilityBeck’s durable gear train maintains accurate,consistent control element positioning even underthe demanding conditions of an active control loop. Gear trains employ a unique, all spur gearconstruction of heat-treated alloy steels andductile iron. Efficient, wide-face spur gearing essentiallyeliminates wear-induced backlash andpositioning inaccuracies. Durable design provides up to 4 days ofprotection against intermittent or extendedaccidental stalls. Individual compartments protect all majorcomponents: Motor, DCM, CPS, gear trainand installation wiring terminal board. Each compartment can be accessed withoutexposing other components. Gasketed, precision-machined coversprovide extra protection for harsh indoor andoutdoor environments. Output and Handwheel shafts are also sealedwith weatherproof, double-lip seals.Mounting VersatilityBeck Actuators can be Mounted in anyOrientation for Greater Installation Flexibility Integral self-locking mechanism ensuresthat drives hold a minimum of 200% of ratedtorque with the motor de-energized.Beck actuators are configured and lubricatedin such a way that they may be mounted inany convenient position. This flexibility allowsactuators to be installed in hard-to-fit locations.Manual HandwheelIf housing compartments are accessible,there are no mounting orientation limits.Convenient Manual Control Without DeclutchAn easy-to-turn, spoke-free Handwheel isincorporated into the Group 11 design to allowmanual operation during installation or poweroutages. Handwheel can be used to move valves anddampers to any position smoothly and easilyunder full load conditions. Mechanical stops in housing prevent manualovertravel. The motor operates at 72 or 120 RPM, so theHandwheel poses no safety hazard.HousingSuperior Protection and ConvenientAccess to ComponentsBeck actuators feature a cast aluminumbody with individual compartments to protectcomponents from moisture and dirt, and alloweasy access for installation and calibration. Precision-machined aluminum alloy castingswith corrosion-resistant poly-urethane paintprovide a rugged, dust-tight, weatherproofType 4X enclosure. Models approved foruse in Hazardous classified locations areavailable—contact a Beck Sales or ApplicationEngineer for details.Mounting ArrangementsDirect-Coupled ConfigurationsA factory machined coupling is used toconnect the actuator directly to the valve. Thisconfiguration is compact in design and is idealfor applications where a constant torque isdesired over the full 90º range of travel.Crank Arm / Linkage ConfigurationsValve / actuator assemblies may bespecified with crank arm and linkage mountingarrangement. This design allows 100º actuatortravel, thus providing variable torque distributionand increased seating effectiveness. With linkage characterization, high seatingtorques can be obtained for certain valvetypes. Standard bracket and linkage mountinghardware is available for most popular valvetypes. Custom mountings are easily handledallowing Beck actuators to be economicallymounted to virtually any rotary valve.
