Vuba aha, uruganda rurimo gukora icyiciro cy'ibicevalve yo gupfuka, valve izunguruka ni valve y'icyerekezo kimwe, ikoreshwa cyane cyane mu buhanga bwa hydraulic n'izindi nzego.

Iyo urugi rufunze, igice cy'urugi gifungwa bitewe n'uburemere bwarwo cyangwa uburemere bwarwo. Iyo amazi ava ku ruhande rumwe rw'urugi ajya ku rundi, imbaraga z'amazi zisunika igice cy'urugi cy'urugi, bigatuma ruzenguruka ku ruhande rw'urugi maze rugakinguka, bityo amazi akanyura neza. Iyo amazi atemba mu buryo bunyuranye, bitewe n'igitutu cy'amazi n'uburemere bw'urugi ubwarwo, urugi ruzahita rufunga kugira ngo hirindwe ko amazi atemba mu buryo bunyuranye, kugira ngo hagerwe ku musaruro w'amazi atemba mu buryo bumwe.

Urugero, aho imiyoboro imwe n'imwe isohoka, urugi rurafungurwa mu gihe cy'amazi asanzwe, kandi iyo habayeho akamenyero ko amazi asubira inyuma nyuma yo kuvamo amazi, urugi ruzafungwa kugira ngo hirindwe ko amazi asubira inyuma.

Muri sisitemu yo kuhira, valve izengurutse ishobora gushyirwa aho umuyoboro w’amazi usohoka. Iyo bikenewe kuhira, amazi asohoka mu muyoboro agasunika urugi rw’ivomero, bigatuma amazi yinjira mu murima. Nyuma yo kuhira, urugi rurafungwa kugira ngo hirindwe ko amazi yabura mu muyoboro n’imyanda yo hanze yinjira mu muyoboro.

Muri sitasiyo y'amazi yo mu mujyi, iyo sitasiyo y'amazi itemba, urugi rw'amazi ruzunguruka rurafungurwa, kugira ngo amazi y'imvura ashobore gusohoka neza mu migezi no mu biyaga; Nyuma yo gusohora amazi, bishobora kubuza amazi yo mu kiyaga cy'uruzi gusubira muri sitasiyo y'amazi yo mu ruzi, kugira ngo hirindwe ko sitasiyo y'amazi yuzura. Byongeye kandi, aho amazi asohokera mu bigega bimwe na bimwe, niba bikenewe gukumira ko amazi asubira inyuma, valve y'amazi ishobora no kugira uruhare runini mu kugenzura amazi mu buryo bumwe.

Valve zo gukoresha mu buryo nk'ubwo zirimo Valve Idasubira. Valve ya Jinbin ihindura urukurikirane rw'valve nkavalve y'irembo, icyuma kitagira umwandairembo rya penstock, valve y'ibinyugunyugu ifite uburebure bubiri, valve nini y'umurambararo w'umwuka, valve yo kugenzura amazi, valve yo gusohora amazi, n'ibindi. Niba ufite ibyo ukeneye bifitanye isano, andika ubutumwa hepfo. Uzabona igisubizo mu masaha 24 kandi witeguye gukorana nawe.
