Ngokuthuthuka komnotho womhlaba kanye nokuthuthukiswa kwezinga lezimboni, kanye nemfuneko yokulawula eqinile yemingcele yezimboni, izimboni eziningi ziqala ukuphishekela ukulawula okuzenzakalelayo.Bazosebenzisaelectric actuator butterfly valve, i-valve yebhola ye-actuator kagesi, i-valve yokulawula kagesi, i-valve ye-diaphragm kagesi, i-valve yokulawula umoyanjalo njalo.Kodwa-ke, ukuqaliswa kokulawula okuzenzakalelayo komthelela omkhulu wemingcele yi-i-actuator.

Kunezinhlobo ezimbili eziyisisekelo zokusebenza kwe-valve okufanele zicatshangelwe lapho ucubungula izidingo ze-automation, okungukuthi, ukukhetha kwe-actuator.

Enye i-angular-stroke actuators, njengama-actuator kagesi e-quarter-turn, ama-activator we-pneumatic asebenza kanye, nama-activator pneumatic actuators.Lawa ma-actuator azungeza kuma-degree angama-90 ngokuya ngetorque edingekayo.Itholakala nge-valve yebhola, i-butterfly valve, i-valve yesango, inhlanganisela ye-globe valve.

I-torque ye-quarter-turn actuator kagesi efika ku-4000Nm, futhi ingalawulwa ngesandla.Kunamamodeli angu-4 ongawakhetha, okungukuthi uhlobo lokushintsha, uhlobo lokulungiswa, uhlobo oluhlakaniphile, uhlobo lokufakazela ukuqhuma kanye nohlobo lokusetha kabusha okuhlakaniphile, lungasetshenziswa kabanzi emikhakheni ehlukene.Intengo efinyelelekayo, engabizi kakhulu, ethandwa kakhulu emakethe.

Ama-actuator we-pneumatic kanye ne-hydraulic avame kakhulu ngoba awadingi amandla nesakhiwo esilula, ukusebenza okuthembekile, isivinini sokushintsha sishesha kakhulu, okufanayo kungasetshenziswa nge-valve yebhola kanye ne-butterfly valve, ngakho insimu ibanzi kakhulu.

Enye i-valve enamajika amaningi, eyaziwa nangokuthi i-stroke eqondile.Lawa ma-valve angaba isiqu esiphakamisayo esingaphenduki noma isiqu esingaphenduki esingaphakamisi, esidinga ukuzungezisa okwengeziwe ukushayela i-valve endaweni evulekile noma evaliwe.Ama-valve ama-Multi-turn ahlanganisa nge-Valve (i-globe valve), i-valve yesango, i-valve yesango lommese nokunye.

Phakathi kwazo, i-fluid-driven multi-rotary noma i-linear output actuator ivame ukusetshenziselwa ukusebenza nge-valve (i-valve ye-globe) ne-valve yesango, ngenxa yesakhiwo sayo esilula, ukusebenza okuthembekile, kulula ukufeza imodi yokusebenza ehlulekayo.Ngokuvamile, ama-actuator kagesi amaningi asetshenziselwa ukushayela ama-valve esango kanye nama-globe, futhi ama-hydraulic noma ama-pneumatic actuators acatshangelwa kuphela lapho kungekho mandla atholakalayo.

Kungenjalo, amasilinda womoya noma awe-hydraulic noma ama-actuator amafilimu anomphumela womugqa nawo angashayela ivalvu.
