Ii-activators ezininzizisetyenziselwa ikakhulu ukulawula ukuvulwa kunye nokuvalwa kweevalvu zentshukumo ezihambelanayo, ezinjengeevalve zesango kunye neevalvu zokumisa.Xa i-actuator yokujika kaninzi isetyenziswa kunye ne-injini yomoya, ingasetyenziselwa ukulawula ukuvulwa / ukuvala iivalve zebhola kunye ne-butterfly valves.
Kweli nqaku, siya kucebisa abavelisi be-actuator aba-5 abatshintshileyo kuwe, ngethemba lokukunceda ukhethe umthengisi ofanelekileyo.

I-COVNA yasekwa kwi-2000 kunye neziqinisekiso ze-ISO.Iminyaka engama-20+ yamava kwishishini le-actuator kunye nevalvu.Sizibophelele ekuncedeni umxhasi wethu ukusombulula isisombululo sokulawula ulwelo.Wamkele nayiphi na imibuzo evela kuwe! sales@covnavalve.com

IBettis luphawu oluphantsi kwe-Emerson, elizinikele ekuboneleleni ngezixhobo ezizisebenzelayo ezibalaseleyo kwintengiso kunye nokunceda ekusombululeni imingeni kulawulo lwenkqubo.I-Bettis inomgca wemveliso obanzi onokukubonelela ngephakheji yokusebenza yevalve ye-turnkey.
Iimveliso zikaBettis zinokusebenza kwishishini lemichiza, indawo yokucoca ioyile, umzi-mveliso wokutya kunye namanye amashishini.

Iqela le-CW Valve lineminyaka engaphezu kwama-60 yamava kwimarike yevalvu, kwaye lizimisele ukubonelela ngeevalvu eziphucukileyo nezintsha kunye nobuchwepheshe bezityalo zamandla ehlabathi, i-oyile negesi, amashishini ekhemikhali kunye namanye amashishini, ukunceda amashishini asebenza kuwo ukuphucula imveliso. ukusebenza kakuhle kunye nokufumana iimarike ezininzi.Yabelana.
Iimveliso ziquka ii-actuator zombane ezininzi ezijikayo, ii-hydraulic actuators njalo njalo.

I-Rotork yasekwa ngo-1957. Emva kweminyaka engaphezu kwama-60 yophuhliso, i-Rotork ngoku yenye yabakhiqizi abahamba phambili be-activator ehlabathini.Iimveliso zeRotork zisebenzela i-oyile kunye negesi, unyango lwamanzi, iikhemikhali, kunye namashishini okulungisa, kwaye zibonelela ngeemveliso ezenziwe ngokufanelekileyo kula mashishini.Izisombululo zolwelo oluzenzekelayo.

I-AUMA yasekwa ngo-1964, sele ikwishishini le-automation actuator iminyaka engaphezu kwama-50, kwaye kungokunje yenye yabakhiqizi abaphambili kolu shishino.Iimveliso zisebenzela ishishini lamandla, ishishini lamanzi, ishishini lepetrochemical njalo njalo.I-AUMA inabasebenzi abangama-2,600 ehlabathini lonke kunye neeofisi ezingama-30 ehlabathini lonke, ezibonelela ngeenkonzo zokusabela ngokukhawuleza kubathengi abavela kwihlabathi lonke.

I-Limitorque iphuhlise phantse iminyaka engama-90, ibonelela abathengi ngezisombululo ezizenzekelayo kunye neemveliso ezithembekileyo kunye nezomeleleyo.I-Limitorque ii-actuator zombane ezininzi ezijikayo zibonelelwa ngoyilo olungenelelayo nolungaphazamisiyo kwiimfuno zakho.
