Esikhathini sokucima umlilo, ama-valves adlala indima ebalulekile ekuphetheni ukugeleza kwamanzi noma amanye ama-ejenti okucisha umlilo. Izinhlobo ezimbili zama-valve asetshenziswa kakhulu kulo mkhakha ama-valves wevemvane nama-valve ebhola. Ngenkathi lezi zinhlobo ezimbili zama-valves zisebenzela izinjongo ezifanayo, zinokwehluka okubalulekile okubenza balungele izimo ezithile.
Omunye womehluko omkhulu phakathi kwama-batterfly valves nama-valve ebhola ukwakheka kwawo. I-valve yamabhabhathane, njengoba igama libonisa, liqukethe i-disc ejikeleza ngepayipi ukulawula ukuhamba. I-disc inamathiselwe kwinduku yensimbi (ebizwa ngokuthi yisiqu) esiguqulwe yisandla noma e-actuator. Ngakolunye uhlangothi, ama-valves, asebenzisa ibhola eliyindilinga elinomgodi enkabeni yokulawula ukuhamba. Ibhola linesibambo noma i-lever elingajikelezwa ukuvula noma ukuvala i-valve.
Omunye umehluko ophawulekayo yindlela yokubeka uphawu. Ku-valve butterfly, i-disc yakha ngokumelene nophawu lwenjoloba (olubizwa ngokuthi isihlalo) esisendaweni yomzimba we-valve. Lo mklamo uvumela ukusebenza okusheshayo nokulula. Esikhundleni salokho, ama-valves ebhola asebenzisa izindawo ezimbili zokubopha uphawu, okuvame ukwenziwa nge-teflon, ukuhlinzeka uphawu oluqinile lapho kuvaliwe. Lokhu kucushwa kuthuthukisa ukusebenza kokubekwa uphawu kwe-valve, okwenza kube lula ukuthi izinhlelo ezidinga ukuvalwa okuqinile.
Uma kukhulunywa ngokulawula ukugeleza, womabili uvemvane nama-valves ebhola anikela ukusebenza okuhle kakhulu. Kodwa-ke, ama-butterfly valves ayaziwa ukuthi ahlenge ngokucindezela okuphansi kokuqhathaniswa nama-ball valves. Lokhu kusho ukuthi amandla amancane adingekayo ukucindezela amanzi noma amanye ama-ejenti wokucindezela umlilo nge-valve butterfly, kunciphisa izindleko zokuposela. Ngakolunye uhlangothi, ama-valves anikela ngokuvuleka okugcwele, okuvumela ukuhamba okungavinjelwe nokulahleka okuncane kwengcindezi, okwenza kube kuhle ngezicelo eziphakeme kakhulu.
Ngokuya kwezindleko, ama-butterfly valves ngokuvamile abiza kakhulu kunama-valve ebhola. Ama-butterfly valves'Idizayini elula kanye nokusebenza kalula kufaka isandla ekufinyeleleni kwabo. Ngaphezu kwalokho, ngenxa yophawu lwenjoloba, i-butterfly valve ayithambekele ekuvuzeni, ngaleyo ndlela kunciphise izindleko zokulungiswa.
Ngamafuphi, kuyilapho womabili ama-butterfly valves nama-valves ebhola alungele izinhlelo zokuvikela umlilo, ukungezwani kwabo okubalulekile kubenza balungele izimo ezithile. Cabanga ngezidingo ezithile zohlelo lwakho lokuvikela umlilo bese uthintana nochwepheshe ukuthola ukuthi iyiphi i-valve (butterfly noma i-ball valve) iyisinqumo esihle kakhulu sezidingo zakho.
