Ii-automated rotary actuatoriyithuluzi lemboni elingasiza ukulawula uketshezi ukude futhi kube lula.I-COVNA inikezela ngazo zonke izinhlobo zama-rotary actuators ezishintshayo njengama-activator kagesi nama-actuator omoya ngezinketho zakho.Ukukusiza ukwandisa ukukhiqiza.Siyakwamukela noma yimiphi imibuzo evela kuwe! sales@covnavalve.com

I-Rotork yethula i-actuator yayo yokuqala ngo-1957 futhi yavula ifektri e-UK ngo-1961. Ikomkhulu lamanje liseBath, UK.
I-Rotork ihlinzeka ngezixazululo zezinsimbi zamadrayivu ezimboni nokulawula ukugeleza, futhi ingumnikezeli ohamba phambili emhlabeni wama-actuator namavalvu.Izimboni zesevisi zifaka, kodwa azikhawulelwe, izimboni ezishintshayo ezifana nowoyela negesi, ukuhlanza amanzi, ukuhlanza amanzi angcolile, amandla kagesi, amandla, imboni yamakhemikhali, kanye nemboni yezemithi.
Imikhiqizo ye-Rotork ihlanganisa ama-actuator kagesi, ama-pneumatic actuators, amabhokisi egiya, izesekeli zamavalvu, izinsimbi, njll.

I-Auma ingomunye wabakhiqizi abahamba phambili bama-actuator kagesi abanolwazi olungaphezu kweminyaka engama-50.Nikeza ngemikhiqizo yekhwalithi ephezulu nethuthukile yemboni yamandla, imboni yamanzi, imboni ye-petrochemical, izimayini, kanye nemboni yamandla enuzi.Sizibophezele ekuhlinzekeni izixazululo ezizenzakalelayo zokuma okukodwa kumakhasimende ezimboni nawezohwebo.
Njengamanje i-AUMA inabasebenzi abangu-2,600 kanye namahhovisi angaphezu kuka-30 emhlabeni wonke ukuze ikunikeze izinsiza ezilula nezisheshayo.
Imikhiqizo ye-AUMA ihlanganisa i-multi turn actuator, i-part turn actuator, i-linear actuator, ibhokisi legiya, njll.

I-Air Torque yasungulwa ngo-1990 futhi izinze e-Italy.Ingumkhiqizi ohamba phambili emhlabeni wama-rack kanye nama-pinion actuators womoya.Itorque yomoya ihlinzeka ngemikhiqizo eseqophelweni eliphezulu futhi emisha yamakhemikhali, i-petrochemical, imithi, amandla, izimboni zikagesi, nokwelashwa kwamanzi.
Imikhiqizo yetorque yomoya ithole isitifiketi se-ISO9001:2008.

I-Bettis iwuhlobo lwe-Emerson, eyasungulwa ngo-1929. Ingumkhiqizi ohamba phambili wama-actuator kagesi, ama-pneumatic actuators nama-hydraulic actuators.Nikeza ngephakheji ehlanganisiwe ye-turnkey valve automation yamakhasimende ezimboni nawezohwebo.

Yasungulwa ngo-1994, i-AT Control ikomkhulu e-United States, futhi njengamanje inamahhovisi ezifundeni eziningi emhlabeni jikelele, njengeNyakatho Melika, i-Asia Pacific, iNingizimu Afrika, njalonjalo.Nikeza ngokuthengisa nesevisi kumakhasimende emhlabeni jikelele.
Imikhiqizo ye-AT control ihlanganisa ama-actuator nama-valve ahlukahlukene.
