Mu bisanzwe solenoid valves ni valve iguma ifunguye kiretse iyo ikoreshejwe. Iyo ingufu zikoreshejwe, zica zifunga, ziguma ziguma zimara igihe cose zifise inguvu. Kubera ingene bifunga, ivyo ntibigenewe gukoreshwa ubudasiba amasaha arenga makeyi. Ni amahitamwo meza cane ku bihe aho umupfunda ukeneye gufunga gusa kugira ngo utere gusa, kandi ukwiye kuguma ufunguye kenshi.
Igikorwa kijanye n’ivyuma vy’amazi vy’i Normally Open ni ngirakamaro mu bihe bikenewe kugira ngo amazi agende igihe cose. Akarorero keza ni umunara wo gukonjesha w’uburyo bw’inganda bukwiye kwama buriko kugira ngo ntihagire ugushuha cane. Muri ivyo, iyo solenoid iragira inguvu gusa (gufunga igihimba c’umubiri) iyo hakenewe vy’ukuri kuyifunga, nk’akarorero, mu gihe c’ugusanura canke gusanura.
