1.5.1Lifetimeofactuators
The lifetime ofan electricactuator(EA)isat least 6 years.
EA used forclosing mode (closingvalves) complywiththe requirementsforat least 15,000 working cycles
(cycle C –O– C:forlinearEA).
EA used forregulating/modulating operation (controlvalves) complywith the belowstatednumbers of operating
hours at the totalnumberof1 million start-ups:
Switching frequency
max. 1,200 [h-1] 1,000 [h-1] 500 [h-1] 250 [h-1] 125 [h-1]
Minimallifetime expectancy– numberofoperating hours
850 1,000 2,000 4,000 8,000
Time of netoperation ismin. 200 hours, max. 2,000 hours.
Lifetime atoperating hours dependson loadingandswitching frequency.
Note : High switching frequencydoesnot ensure betterregulation. Setting ofregulation parameters should be
therefore made with the inevitablynecessaryswitchingfrequencyneededforthe process in question.
1.6Operation conditions
1.6.1Productlocation and operation position
Electricactuators maybe installedandoperated inenclosed locationsofindustrialfacilitieswithno
temperatureand moistureregulation, protected fromdirectclimaticeffects(suchasdirectsunlight).Moreover,
special“marine”versionsmaybe used inwaste watertreatment applications,watermanagement, selected
chemicalapplications,tropicalenvironmentsand coastalareas.
Installation and operationof EA ispossiblein anyposition. Verticalposition ofoutput partaxisandwith
the controlpart above the valveisusual. Electricactuatorposition underthe valvenot recommended.
Warning:
When the EAisinstalled inopen air, itmustbe sheltered lightlyto protect isagainstdirecteffectsof
atmosphere.
When installed inthe areaswithrelativehumiditymorethan80%,inopenairunderashelteris
needed to connect the space heaterdirectly– without a thermalswitch.

2.Description, function and specifications
2.1Description and function
The ST1, STR 1 electricactuators consist ofthree partsdiffering intheirfunction.
The gearpart ismade up bya flangeadapter,orwith pillars withaflangewithaconnectingpartfor
connection onto acontrolled device, and gears placed inthebottom;on the otherside drivemechanismsfor
controlpart unitsare surfaced.
The control part(Fig. 3) isplaced on a controlboard (2)consisting of:
•an electricmotor(7)(at single-phaseversionwith capacitor)
•a thrust unit(controlledwitha wormaxialshift)
•aposition-signalling unit(3)withapositiontransmitter(5)- positioner(resistive-potentiometer,capacitiveor
an electronicposition transmitter) and with a mechanicallocalposition indicator
•a space heaterwith a thermalswitch (8)
•electricconnection isrealised using terminal boards (6) (located inthe controlarea)andcablebushings
(12), or connector with cablebushings
The STR1 version isequipped withan electronic controller.The electroniccontrollerallowsautomaticoutput
unitposition adjustment independencyon input signalvalueand providesadditionalfunctions.
Additional accessories:
Manual control:made up bya hand wheelwith awormgearing.
Local electric controlmodule.
The STR version isequipped withan electroniccontroller.The position controllerallowsautomaticposition
adjustment ofthe EAoutput part dependingupon the input signalvalueand providesalsoadditionalfunctions.
