Mavavu amatha kugawidwa m'mafakitale ndi ma valve aboma, ma valve aboma kuti agwiritse ntchito malo ocheperako, makamaka pamadzi atsiku ndi tsiku, kutentha, gasi, ndi zina zambiri, valavuyo imakhala yovuta kwambiri; ndi mavavu mafakitale ntchito zinthu ndi mkulu ntchito kapena nkhanza, nthawi zambiri amafuna mavavu ndi kutentha, kuthamanga, dzimbiri ndi makhalidwe ena. Mavavu aku mafakitale atha kugawidwanso kukhala ma valve owongolera omwe amapangidwa m'mafakitale (ie mavavu owongolera) ndi mavavu apamafakitale (ie mavavu opangira). Ma valve olamulira ndi ma valve opangira ma valve kuphatikizapo kusiyana kwa kayendetsedwe ka kayendetsedwe kake, kusiyana kwakukulu ndiko kugwiritsa ntchito zochitika ndikukwaniritsa ntchito zosiyanasiyana. Industrial mavavu Buku akhoza kuzindikira awiri udindo pa malo ntchito yotseguka ndi kutseka, ndipo kwenikweni ntchito zochitika kukhalabe dziko kwa nthawi yaitali, kawirikawiri amafunika opareshoni, zovuta zimachitika kuvala ndi kung'ambika, ntchito yaitali. moyo. Monga chimodzi mwa zida zazikuluzikulu zoyang'anira gawo la mafakitale, valavu yoyang'anira mafakitale imaphatikiza zida, makina, mphamvu zamadzimadzi, kayeseleledwe kamadzimadzi, zamagetsi, masensa, mapulogalamu, kuwongolera ndi matekinoloje ena, ndipo amatenga gawo pakuwongolera njira. ndi zida zina, ndikuwongolera kuthamanga kwa liwiro, kuthamanga, kuti mukwaniritse cholinga chachikulu cha kuwongolera makina opangira mafakitale. Chifukwa cha valavu yamagetsi yamagetsi pakugwiritsa ntchito njira yowongolerera pafupipafupi, kukhalapo kwa media pagulu la valve, kukokoloka kokulirapo, kotero kuti valavu yodziyimira payokha ya mafakitale ndi yamtundu wa 'zowonongeka'.

Ma valve owongolera aku China kuyambira koyambirira kwa 1959 adayamba kupanga ndi kupanga, kuyambika mochedwa. Pa nthawi imeneyo, dziko anasankha kupanga mavavu kulamulira mabizinesi asanu okha, makamaka kukopera mankhwala a Soviet Union wakale, chifukwa cha otsika mwatsatanetsatane Machining, kokha kukwaniritsa zofunika kulamulira ambiri ndondomeko kupanga mafakitale pa nthawi imeneyo. Kuyambira zaka za m'ma 1980, mafakitale ambiri adayambitsa ukadaulo wapamwamba wakunja, kuti apititse patsogolo magwiridwe antchito azinthu zoyambira ndikuwonjezera kukhazikika komanso kusanja pamaziko a chitukuko cha mavavu owongolera apneumatic ndi ma valve opepuka owongolera ndi zinthu zina zatsopano, China. ma valve owongolera kuti akwaniritse chitukuko cha kudumpha. M'zaka za m'ma 21, kukula kwa mafakitale kumapangitsa ma valve owongolera ndi ukadaulo wowongolera makina, kuwongolera makina kukukulirakulira kukhala chinthu chofunikira kwambiri pamagetsi owongolera, makampani anzeru aku China owongolera ma valve alowa m'nthawi yachitukuko chofulumira.
