Ngophuhliso loqoqosho lwehlabathi kunye nokuphuculwa kwenqanaba lemizi-mveliso, kunye nemfuneko yolawulo olungqongqo lweeparamitha zoshishino, amashishini amaninzi aqala ukulandela ulawulo oluzenzekelayo.Baya kusebenzisaivelufa yebhabhathane ye-actuator yombane, ivelufa yebhola ye actuator yombane, ivalve yokulawula umbane, ivelufa ye-diaphragm yombane, ivelufa yokulawula umoyakwaye nangokunjalo.Nangona kunjalo, ukuphunyezwa kolawulo oluzenzekelayo lwempembelelo ephambili yeeparamitha yii actuator.

Kukho iindidi ezimbini ezisisiseko zokusebenza kwevalvu ekufuneka ziqwalaselwe xa kuqwalaselwa iimfuno zokuzenzekelayo, oko kukuthi, ukhetho lwe-actuator.

Enye i-angular-stroke actuators, efana ne-quarter-turn actuators yombane, ii-activators ze-pneumatic ezisebenza ngokunye, kunye ne-double-acting pneumatic actuators.Ezi actuators zijikeleza kwii-90 degrees ngokwetorque efunekayo.Ifumaneka ngevalve yebhola, ivalve yebhabhathane, ivalve yesango, indibaniselwano yevalve yeglowubhu.

I-torque ye-quarter-turn actuator yombane ukuya kwi-4000Nm, kwaye inokulawulwa ngesandla.Kukho iimodeli ezi-4 onokukhetha kuzo, ezizezi, uhlobo lokutshintsha, uhlobo lohlengahlengiso, uhlobo olukrelekrele, uhlobo lobungqina bokudubula kunye nohlobo lokusetha kwakhona olukrelekrele, lunokusetyenziswa ngokubanzi kwiinkalo ezahlukeneyo.Ixabiso elifikelelekayo, ixabiso eliphezulu, elithandwa kakhulu kwimarike.

I-actuator ye-pneumatic kunye ne-hydraulic actuators ixhaphake kakhulu kuba ayifuni amandla kunye nesakhiwo esilula, ukusebenza okuthembekileyo, isantya sokutshintsha sikhawuleza kakhulu, okufanayo kunokusetyenziswa kunye nevalve yebhola kunye ne-butterfly valve, ngoko intsimi ibanzi kakhulu.

Enye ivalve yokujika kaninzi, ekwabizwa ngokuba sisibetho esithe ngqo.Ezi zivalo zinokuthi zibe yi-stem ephakamisayo engajikeleziyo okanye i-stem ejikelezayo engaphakamisiyo, efuna ukujikeleza okongeziweyo ukuqhuba i-valve kwindawo evulekileyo okanye evaliweyo.Iivalve ezininzi ezijikayo ziquka ngeValve (ivalve yeglowubhu) , ivalve yesango, ivalve yesango lemela njalo njalo.

Phakathi kwabo, i-fluid-driven multi-rotary or linear output actuator isoloko isetyenziselwa ukusebenzisa i-valve (i-valve ye-globe) kunye ne-valve yesango, ngenxa yesakhiwo sayo esilula, ukusebenza okuthembekileyo, kulula ukufezekisa imodi yokusebenza engaphumeleli.Ngokuqhelekileyo, ii-actuator zombane ezijikelezayo ezininzi zisetyenziselwa ukuqhuba iivalve zesango kunye neglobhu, kunye ne-hydraulic okanye i-pneumatic actuators ziqwalaselwa kuphela xa kungekho mandla akhoyo.

Ngenye indlela, iisilinda ze-pneumatic okanye i-hydraulic okanye ii-actuator zefilimu ezinemveliso yomgca nazo zinokuqhuba ivalve.
