1. Kufuneka kubekho itorque eyaneleyoi actuatorisiphumo sayo kukujika i-engile kunye namandla aneleyo e-actuator ephuma kuyo kukushenxiswa komgama ukoyisa ukuxhathisa komthwalo.Ngokukodwa, i-high-temperature kunye ne-high-pressure valves, ukutywinwa kwayo ukupakisha uxinzelelo kuqinile, emva kwexesha elide ukuvula ngokuphindaphindiweyo ngaphezu kwemeko eqhelekileyo ukuchitha amandla amaninzi, njengoko isantya sesenzo asiyomfuneko ukuba siphakame kakhulu, kuba ukulawulwa kokuhamba kwaye ulawulo akufuneki lukhawuleze kakhulu.Ukonyusa i-torque okanye amandla, i-motor output shaft reducer, ukuba i-motor ngokwayo inesantya esiphantsi, isinciphisi sinokuba lula.

2. Kufuneka kubekho i-self-locking feature kwi-transmission system ye-reducer okanye i-motor.Xa i-motor ingasebenzi, umthwalo ongalinganiyo (ofana ne-deadweight ye-valve yesango) awunakubangela naluphi na utshintsho kwi-angle okanye ukufuduka.Ke ngoko, kuhlala kuyimfuneko ukusebenzisa isixhobo segiya yeentshulube okanye ibrake ye-electromagnetic.Ngalo mlinganiso, xa kwenzeka ukungaphumeleli kwamandla okungalindelekanga, indawo yevalve inokugcinwa kwindawo phambi kokungaphumeleli kwamandla.

3. Kwimeko yokumka kombane okanye ukusilela kwe-regulator, kufuneka kube lula ukusebenza ngesandla kwi-activator ukuthatha inyathelo likaxakeka.Ukwenza oku, kufuneka ube ne-clutch kunye ne-handwheel.

4. Isignali yokulandelela indawo ye-valve kufuneka inikezelwe kwi-activator ngexesha lokusebenza ngesandla ukwenzela ukubonelela ngesiseko sokulandelela ngokuzenzekelayo kumlawuli (isidingo sokungabikho kokuphazamiseka) .Le ayisiyiyo kuphela i-activator ngokwayo ibeka iimfuno zempendulo, kodwa kunye neemfuno zokubonisa indawo yevalvu.

5. Yiba nesalathisi esijonga indawo yevalvu.Isalathisi sifakwe kwi-shaft ephakathi ukuze indawo yevalve ibonwe.ILens idla ngokuba yiLens econvex etywinwa kakuhle kwaye akukho mfumba kwamanzi.

6. Ukuze ukhusele i-valve kunye nokuhanjiswa kumandla okusebenza ngokugqithiseleyo kunye nomonakalo, i-actuator kufuneka inqunywe ngesixhobo kunye nokunciphisa amandla okanye izixhobo ze-torque.Ukongeza kwiimfuno ezisisiseko ezingentla, ukwenzela ukuququzelela kunye neentlobo zeempawu zevalve, ingaba kwi-activator kunye neempawu zedijithali ezichanekileyo.Kwiminyaka yakutshanje kukwakho nomsebenzi wokusebenza kwe-PID ye-activator, ebizwa ngokuba "yi-digital actuator" kunye "ne-activator ehlakaniphile.I-DKJ (i-angle yokujikeleza) kunye ne-DKZ (i-linear displacement of output) , ezisetyenziswa ngokubanzi kwizixhobo zokudibanisa iyunithi yombane kwilizwe lethu, ziseyi-analog actuators yombane.
