Ama-valve angahlukaniswa abe ama-valve ezimbonini nama-civil valves, ama-valve omphakathi ukuze asetshenziswe izimo zokusebenza eziphansi kakhulu, ikakhulukazi emanzini nsuku zonke, ukushisa, igesi, njll., i-valve ayifuni kakhulu; kanye nama-valve ezimbonini ukuze kusetshenziswe izimo zokusebenza eziphakeme kakhulu noma ezinokhahlo, ngokuvamile zidinga ama-valve anokushisa okuphezulu, ukucindezela okukhulu, ukugqwala nezinye izici. Amavalvu ezimbonini angaphinde ahlukaniswe abe amavalvu okulawula okuzenzakalelayo ezimbonini (okungukuthi amavalvu okulawula) kanye namavalvu enziwa ezimbonini (okungukuthi amavalvu enqubo). Ama-valve okulawula kanye nama-valve okucubungula ngaphezu kokuhluka kwemodi yokulawula, umehluko omkhulu kakhulu ukusetshenziswa kwendawo yesehlakalo nokufeza imisebenzi ehlukene. Ama-valve okwenziwa ezimbonini angakwazi ukubona kuphela ukusebenza kwezindawo ezimbili esizeni kokuvula nokuvala, futhi esimweni sohlelo lwangempela lokulondoloza isimo isikhathi eside, akuvamile ukuthi kudingeke ukuthi sisetshenziswe, akulula ukuthi kwenzeke ukuguga nokukhala, isevisi ende. ukuphila. Njengenye yemishini ebalulekile yokulawula isiphetho emkhakheni wokulawulwa kwenqubo yezimboni, i-valve yokulawula okuzenzakalelayo yezimboni ihlanganisa izinto zokwakha, imishini, amandla oketshezi, ukulingisa uketshezi, ama-electronics, izinzwa, isofthiwe, ukulawula nobunye ubuchwepheshe, futhi idlala indima ekulawuleni inqubo. ngezinye izinsimbi, ngenkathi ilawula ukunemba kwezinga lokugeleza, ingcindezi, ukuze kufinyelelwe umgomo wokugcina wokulawula okuzenzakalelayo kwemboni. Ngenxa ye-industrial othomathikhi yokulawula i-valve ekusetshenzisweni kwenqubo yokulawula imvamisa iphezulu, ukuba khona kwemidiya emzimbeni we-valve, ukuguguleka okukhudlwana kwe-spool, ngakho-ke i-valve yokulawula okuzenzakalelayo yezimboni ingeyohlobo 'lwezinto ezisetshenziswayo'.

Ama-valve okulawula e-China kusukela ekuqaleni kuka-1959 aqala ukukhiqiza nokukhiqiza, isiqalo sekwephuzile. Ngaleso sikhathi, ukukhiqizwa kazwelonke eziqokiwe control valve amabhizinisi amahlanu kuphela, ikakhulukazi ukukopisha imikhiqizo yangaphambili iSoviet Union, ngenxa ukunemba ongaphakeme machining, kuphela ukuhlangabezana nezidingo zokulawula jikelele inqubo ukukhiqizwa ezimbonini ngaleso sikhathi. Kusukela ngeminyaka yawo-1980s, izimboni eziningi zethule ubuchwepheshe obuthuthukile bangaphandle, ukuze kuthuthukiswe ukusebenza komkhiqizo wokuqala kanye nokuqhubeka nokumiswa kanye nokuhlelwa kabusha ngesisekelo sokuthuthukiswa kwama-valve okulawula umoya abekwe eceleni kanye nama-valve okulawula angasindi neminye imikhiqizo emisha, yaseChina. ama-valve okulawula ukufeza ukuthuthukiswa kokugxuma. Ngekhulu lama-21, izinga lokuthuthuka kwezimboni lenza ama-valve okulawula kanye nobuchwepheshe bokulawula okuzenzakalelayo, ukulawula okuzenzakalelayo kuya ngokuya kuba isici esibalulekile sevalvu yokulawula, imboni yama-valve yokulawula ehlakaniphile yaseChina ingene enkathini yokuthuthuka ngokushesha.
