Amazwe Amanyene

I-United States ikwindawo ebalulekileyo kwimarike yeevalvu ezikumgangatho ophezulu, ingakumbi kwiindawo zokusetyenziswa eziphezulu ezifana neenqwelo moya, ioyile kunye negesi. Iinkampani ezinkulu ziquka iCaterpillar, i-Eaton, njl.njl., ezineenzuzo ezibalulekileyo kubuchule bokuvelisa ubuchwepheshe kunye nomgangatho wemveliso.

Jemani

IJamani inembali ende kunye nemigangatho ephezulu kwicandelo leevalvu zoshishino. Iinkampani ezinkulu ziquka iKaiser, iHawe, njl.njl., ezinetekhnoloji ehamba phambili kwihlabathi kunye nesabelo semarike kwiivalvu ze-hydraulic kunye ne-pneumatic.

Japhan

IJapan inedumela eliphezulu ekwenzeni iivalvu ezichanekileyo. Iinkampani ezinkulu ziquka iYokogawa Electric kunye neKawasaki Heavy Industries, ezineengenelo zobugcisa ezikhethekileyo ekulawuleni oomatshini kunye noomatshini abachanekileyo.

Amanye amazwe

Ukongeza kula mazwe angentla, amanye amazwe afana ne-Itali, iFransi, iSouth Korea, njl. nawo anesabelo esithile kwicandelo lokwenziwa kweevalvu, ngakumbi kwiindawo ezithile zokusetyenziswa, njengeDanfoss Group yase-Itali inesikhundla esiphambili kwicandelo leevalvu zokulawula ubushushu, iPalmer yaseFransi inesabelo esiphezulu kwimarike kwiivalvu zoshishino, kwaye iSamsung Heavy Industries yaseMzantsi Korea inentsebenzo ebalulekileyo kwicandelo leevalvu ezinoxinzelelo oluphezulu.

Iinkampani kula mazwe zineempawu zazo ekuveliseni iivalvu kunye nokuvelisa izinto ezintsha kwezobuchwepheshe, kwaye zikhuthaze uphuhliso lweshishini leevalvu kwihlabathi liphela.
