Ekucimeni umlilo, ama-valve adlala indima ebalulekile ekulawuleni ukugeleza kwamanzi noma ezinye izinto ezicisha umlilo.Izinhlobo ezimbili zama-valve ezivame ukusetshenziswa kulo mkhakha ama-valve ovemvane nama-valve ebhola.Nakuba lezi zinhlobo ezimbili zama-valve zisebenzisa izinhloso ezifanayo, zinokuhluka okubalulekile okubenza bafaneleke izimo ezithile.
Omunye umehluko omkhulu phakathi kwama-butterfly valves nama-valve ebhola ukuklama kwawo.I-valve uvemvane, njengoba negama libonisa, iqukethe idiski ezungeza epayipini ukuze ilawule ukugeleza.I-disc ixhunywe kwinduku yensimbi (ebizwa ngokuthi i-stem) ephendulwa isondo lesandla noma i-actuator.Amavalvu ebhola, ngakolunye uhlangothi, asebenzisa ibhola eliyindilinga elinembobo phakathi nendawo ukuze alawule ukugeleza.Ibhola linesibambo noma i-lever ekwazi ukuzungeziswa ukuze ivule noma ivale i-valve.
Omunye umehluko ophawulekayo indlela yokuvala uphawu.Ku-valve ye-butterfly, i-disc ivala uphawu lwenjoloba (ebizwa ngokuthi isihlalo) esingaphakathi komzimba we-valve.Lo mklamo uvumela ukusebenza okusheshayo nokulula.Esikhundleni salokho, ama-valve ebhola asebenzisa izindawo ezimbili zokuvala, ngokuvamile ezenziwe nge-Teflon, ukuze anikeze uphawu oluqinile lapho luvaliwe.Lokhu kulungiselelwa kuthuthukisa ukusebenza kokuvala kwe-valve, kuyenze ifaneleke izinhlelo ezidinga ukuvaleka okuqinile.
Uma kuziwa ekulawuleni ukugeleza, kokubili uvemvane nama-valve ebhola anikeza ukusebenza okuhle kakhulu.Kodwa-ke, ama-valve ovemvane ayaziwa ukuthi anomfutho ophansi wokwehla uma kuqhathaniswa nama-valve ebhola.Lokhu kusho ukuthi amandla amancane adingekayo ukusunduza amanzi noma ezinye izinto ezicisha umlilo ngevalve uvemvane, kuncishiswe izindleko zokupompa.Ama-valve ebhola, ngakolunye uhlangothi, ahlinzeka ngokuvuleka okugcwele, okuvumela ukugeleza okungakhawulelwe kanye nokulahlekelwa kwengcindezi encane, okuwenza alungele izinhlelo zokusebenza zokugeleza okuphezulu.
Mayelana nezindleko, ama-valve ovemvane ngokuvamile anezindleko ezingcono kunama-valve ebhola.Ama-valve e-Butterfly'ukuklama okulula kanye nokusebenza kalula kunomthelela ekuthengeni kwazo.Ngaphezu kwalokho, ngenxa yophawu lwenjoloba, i-valve ye-butterfly ayijwayele ukuvuza, ngaleyo ndlela inciphisa izindleko zokulondoloza.
Kafushane, kuyilapho womabili ama-valve ovemvane nama-valve ebhola elungele izinhlelo zokusebenza zokuvikela umlilo, ukuhluka kwawo okubalulekile kuwenza afaneleke kakhulu ezimweni ezithile.Cabangela izidingo ezithile zohlelo lwakho lokuvikela umlilo bese uthintana nochwepheshe ukuze uthole ukuthi iyiphi i-valve (uvemvane noma i-valve yebhola) eyisinqumo esingcono kakhulu sezidingo zakho.
