Iivalvu zinokwahlulwa zibe ziivalvu zoshishino kunye neevalvu zoluntu, iivalvu zoluntu zokusetyenziswa kweemeko zokusebenza eziphantsi, ubukhulu becala kumanzi emihla ngemihla, ubushushu, igesi, njl. njl., ivalve ayifuni kakhulu; kunye neevalvu zoshishino zokusetyenziswa kweemeko zokusebenza eziphezulu okanye ezibukhali, zihlala zifuna iivalvu ezinobushushu obuphezulu, uxinzelelo oluphezulu, ukubola kunye nezinye iimpawu. Iivalvu zemizi-mveliso zinokwahlulwa kwakhona zibe ziivalvu zolawulo oluzenzekela kwimizi-mveliso (okt. iivalvu zolawulo) kunye neevalvu zemisebenzi yeshishini (okt. Iivalve zokulawula kunye neengqungquthela zenkqubo ngaphezu kokungafani kwindlela yokulawula, umahluko omkhulu kukusetyenziswa kwendawo kunye nokufezekisa imisebenzi eyahlukeneyo. Iivalvu ze-Industrial manual zinokuqonda kuphela ukusebenza kweendawo ezimbini kwisiza sokuvula nokuvala, kwaye kwimeko yesicelo sokugcina ukugcina imeko ixesha elide, kunqabile ukuba kuqhutywe, akukho lula ukwenzeka ukuguga kunye nokukrazula, inkonzo ende. ubomi. Njengenye yezixhobo ezingundoqo zokulawula i-terminal kwicandelo lolawulo lwenkqubo yoshishino, ivalve yolawulo oluzenzekelayo kwimizi-mveliso idibanisa izinto, oomatshini, i-fluid dynamics, i-fluid simulation, i-electronics, i-sensor, isofthiwe, ulawulo kunye nobunye ubuchwepheshe, kwaye idlala indima kulawulo lwenkqubo. kunye nezinye izixhobo, ngelixa ulawula ukuchaneka kwezinga lokuhamba, uxinzelelo, ukuze kuphunyezwe injongo yokugqibela yokulawulwa kwe-industrial automation. Ngenxa yokuba ivalve yolawulo oluzenzekelayo kwishishini kwinkqubo yolawulo iphezulu, ubukho bemithombo yeendaba kumzimba wevalvu, ukhukuliseko lwespool olukhulu, ngoko ke ivalve yolawulo oluzenzekelayo yoshishino lolohlobo 'lwezinto ezisetyenziswayo'.

Iivalvu zolawulo zaseTshayina kwasekuqaleni ngo-1959 zaqala imveliso kunye nokuveliswa, isiqalo kade. Ngelo xesha, imveliso emiselweyo yesizwe yolawulo iivalvu kuphela amashishini amahlanu, ikakhulu ukukhuphela imveliso eyayisakuba yiSoviet Union, ngenxa yokuchaneka eliphantsi machining, kuphela ukuhlangabezana neemfuno zolawulo jikelele inkqubo yemveliso yoshishino ngelo xesha. Ukusukela ngeminyaka yoo-1980, iifektri ezininzi ziye zazisa itekhnoloji ephucukileyo yangaphandle, ukuze kuphuculwe ukusebenza kwemveliso yoqobo kunye nokubekwa emgangathweni okungaphezulu kunye nokulandelelana ngokwesiseko sophuhliso lweevalvu zolawulo lwepneumatic ezibekwe ecaleni kunye neevalvu zolawulo olukhaphukhaphu kunye nezinye iimveliso ezintsha, eTshayina. iivalvu zokulawula ukuphumeza uphuhliso lokutsiba. Kwinkulungwane yama-21, inqanaba loshishino lenza iivalvu zolawulo kunye netekhnoloji yokulawula i-automation, ulawulo oluzenzekelayo luya lusiba luphawu olubalulekileyo lwevalve yolawulo, ishishini levalvu yolawulo lwaseTshayina lingene kwixesha lophuhliso olukhawulezayo.
