Valves nimwe mubikoresho byingenzi bya sisitemu yo kugenzura amazi, ubusanzwe bikoreshwa mumazi yo kugenzura amazi cyangwa gaze. Kubwibyo, indangagaciro zikoreshwa cyane mubice bitandukanye byinganda zagenewe kugenzura amazi. Kugeza ubu, ahantu nyaburanga hashyirwa ingufu harimo: peteroli na gaze, ingufu z'amashanyarazi, inganda z’imiti, amazi ya robine no gutunganya imyanda, gukora impapuro, metallurgie, imiti, ibiryo, ubucukuzi, ibyuma bidafite fer, electronics n’inganda. Muri byo, peteroli na gaze karemano, ingufu, ingufu n’imiti ninganda zingenzi zikoreshwa mumibande. Nk’uko imibare ya Valve World ibigaragaza, ku isoko mpuzamahanga ry’inganda zikenerwa n’inganda ku isi, urwego rwa peteroli na gaze, harimo gucukura, ubwikorezi, ndetse n’ibikomoka kuri peteroli, bifite igice kinini cya 37.40%, hagakurikiraho icyifuzo cy’ingufu, ingufu n’imiti, kikaba gifite agaciro k’inganda ku isi. 21,30% by'ibisabwa ku isoko hamwe n'ibisabwa ku isoko mu bice bitatu bya mbere hamwe hamwe bingana na 70.20% by'ibisabwa ku isoko. Mubikorwa byo gukoresha inganda zimbere mu gihugu, imiti, ingufu ningufu, ninganda za peteroli na gaze nabyo ni amasoko atatu yingenzi ya valve. Isoko ku isoko ryabo ryinjije 25,70%, 20,10%, na 20,10% by’isoko rusange ry’imbere mu gihugu rikeneye isoko, byose hamwe bikaba byose hamwe. 60.50% by'ibisabwa ku isoko.

1. AGACIRO KA RADIATORumubiri ushyizwe kumuryango wumuriro. Mugihe ushyiraho, nyamuneka witondere icyerekezo cyamazi atemba kugirango ahuze nicyerekezo cyerekanwe numwambi;

2. Kugirango byoroherezwe kwishyiriraho thermostat, ikiganza kigomba gushyirwa kumwanya ntarengwa wo gufungura (umwanya wa numero 5) mbere yo kwishyiriraho, naho ibinyomoro bifunga bya thermostat bigomba kujugunywa kumubiri wa valve;

3. Kugira ngo wirinde kunanirwa gukora guterwa no gusudira hamwe n’ibindi bisigazwa, umuyoboro na radiator bigomba gusukurwa neza;

4.

5. Imirasire yumuriro wa radiyo igomba gushyirwaho neza kugirango thermostat ishyizwe mumwanya utambitse;

6. Kugirango hamenyekane neza ubushyuhe bwimbere mu nzu, valve ya thermostatike ntishobora gushyirwaho mumashanyarazi. Iyo uyikoresheje, igomba kurindwa izuba ryinshi kandi ntishobora guhagarikwa nibindi bintu.
