They are equipped with electronic stroke adjustment, canaccept analog or digital control signals, and are available with thepatented Enerdrive fail safe are ideal for VAV terminalunits, fan coil units, chilled beams,small heat/cool coils and baseboardradiation for Globe ValvesThe A and M family of linear actuators operate 2 way and 3way globe valves. They areequipped with electronic strokeadjustment, can accept analog,tri-state, on/off and PWM controlsignals and are available with thepatented enerdrive fail safe system. They will adapt to many different makes of globe valves withour retrofit linkage for DampersWe build a comprehensive line ofdamper actuators.
4 The versatilemulti-signal actuators, the fastactuators for precise laboratoryfume hood control and the hightorque U & W actuators place us atthe forefront of actuator for Various Valve TypesNeptronic actuators mount on ballvalves, globe valves and butterflyvalves of different size and make,combining rugged mounting hard-ware with a smooth operation. Forfluid control see our Neptronicvalve for VAV BoxesNeptronic actuators for close con-trol of VAV systems have electronicstroke and zero & span adjust-ment. They are compatible withbuilding automation systems andare easy to install and IntroductionWide SelectionInherent in each Neptronic actuator is the experiencegained in addressing the concerns and requirements ofthe building automation industry. This means simplicity inthe appropriate model selection, quick and easy installa-tion and trouble free commissioning.
5 Only Neptronic offersthe widest selection of torque output, control signals androtational speeds in both fail safe and non-fail safemotors. Only Neptronic developed the patentedEnerdrive System, the modern, electronic replacementfor antiquated spring return. The Neptronic family of actuators isdivided foremost bythe torque capability. Direct coupled models deliver up to18 (C), 35 (D), 50 (B), 70 (S), (L), 180 (T) or 360 (R) at rated voltage andare suitable for applications from small variable air volumeboxes to large air handler dampers. The most powerfulunits available (U & W) produce from 1800 to and are mounted on large butterfly valves, vortexdampers or fan inlet guide signal selection is simple. Choose digital or multisignal (analog) regardless of the size. All digital models,including those with Enerdrive, may be wired for 2 positionor 3 point floating control.
6 Similarly, all multi-signal (analog)models may be wired and calibrated in the field torespond to 2-10 Vdc, 4-20mA, pulse width modulating, 2position or floating control. In addition, the multi signal(analog) motors feature electronic stroke adjustment andzero & span signal is the leader in developing fast response technology. In the B classification, the rotational speed ofthese models varies from to 6 sec. Their primary useis in fume hood damper control in clean room applica-tions. Larger fast response models with the T and R classification have a 20 second timing and are applicablein smoke control, stairwell pressurization and generatorroom installations. For applications where fast responseis not essential, Neptronic s standard models deliverrotational speeds from 60 to 100 sec of quiet, is the only manufacturer to incorporate fail safefunctionality in all its directly coupled actuator modelswithout any changes to physical dimensions, torque outputs, rotational times or control signal is this possible?
7 By inventing, in 1992, a supercapacitive return system called Enerdrive, Neptronic wasable to eliminate the bulky mechanical components thatrequire increased space or that affect either the torque orresponse time. Since its introduction to the HVAC marketplace, Enerdrive has proven its versatility , the Electronic Spring is a system that is fullyincorporated into the PC board for both low and line voltage service. The power generated and stored in itscapacitors will drive the controlled device at full ratedtorque to its safety position. It is 100% operational withthe resumption of power. Enerdrive models may be manually positioned with the clutch override that is standard on all Neptronic actuators. Most importantly, thefinal fail position, either normally open or normally closedmay be chosen at any time either before or after installa-tion with the flick of a dip switch.

Neptronichas standardized its electronic functions and program-ming so that all digital models are wired alike as are allmulti signal (analog) models.

(velocity and static pressure charts for the specific style of damper, ie. Parallel blade, opposed blade, with or without blade seals, etc.)

Note: For off center pivot dampers, the above rules do not hold. For these types of dampers as well as inlet guidevanes or fan vortex dampers, one must obtain the torque requirements from the manufacturer of the ReferencesTo select the Neptronic actuator that directly or most closely replaces models by other manufacturers, visit or contact a cross reference of our old part numbers to our new part numbers, visit or contact ExplainedNeptronic actuator Selection Code B M 0 6 0 F NTORQUESC18 (2 Nm)D35 (4 Nm)B50 ( Nm)S70 (8 Nm)L140 (16 Nm)T180 (20 Nm)R360 (40 Nm)U & W1800 to 4000 (200 to 450 Nm)CONTROL SIGNALTON-OFF/3 point floatingMON-OFF/3 point floating / analog / pwmor analog only (2-10 Vdc)POWER SUPPLY024 Vac or 30 Vdc1120 Vac2240 Vac3120/240 Vac or 24/120/240 VacFUNCTIONS00standard05potentiometer feedback.
