Valve idafite ireme ni ubwoko bwa valve idafite amahame ngenderwaho y’imikorere asobanutse neza. Ibipimo by’imikorere n’ingano byayo byihariye hakurikijwe ibisabwa mu buryo. Ishobora gutegurwa no guhindurwa nta kibazo ku mikorere n’umutekano. Ariko, inzira yo gukora imashini iracyakurikiza ingingo zijyanye n’amahame ngenderwaho y’igihugu.

Igishushanyo mbonera cy'udupira tutari dusanzwe gikwiye kuzirikana ishingiro n'ubushobozi bwo gukora muri rusange. Uretse kwishingikiriza ku nyigisho gakondo, igishushanyo mbonera gikeneye kandi ubushakashatsi n'iterambere bishya. Kubera iyo mpamvu, muri rusange, hari abantu bakomeye mu nganda bagomba kurangiza akazi nk'ako, kandi abahanga mu by'ubwubatsi bazatanga ibishushanyo nyuma y'uko igishushanyo mbonera kirangiye.

Ubwoko bw'udukingirizo tutari dusanzwe bugabanyijemo udukingirizo tw'amazi mabi (valve y'ingobyi ya penstock na flap) n'udukingirizo tw'ibyuma (valve y'ingufu z'ubururu, valve y'ingobyi, valve y'indorerwamo, valve isohora ivu, n'ibindi).
