Valve yo kwagura ni igice cy'ingenzi cya sisitemu yo gukonjesha, akenshi ishyirwa hagati ya silindiri yo kubika amazi n'icyuma gikonjesha. Valve yo kwagura ituma icyuma gikonjesha amazi ku bushyuhe buringaniye n'umuvuduko mwinshi bihinduka umwuka utose ku bushyuhe buri hasi n'umuvuduko muto binyuze mu gukonjesha kwayo, hanyuma icyuma gikonjesha gifata ubushyuhe muri evaporator kugira ngo kigere ku ngaruka zo gukonjesha. Valve yo kwagura igenzura inzira ya valve inyura mu mpinduka z'ubushyuhe bwinshi ku mpera ya evaporator kugira ngo hirindwe ko agace ka evaporator kadakoreshwa neza ndetse n'ibintu bishobora gutuma silindiri igwa.
Mu magambo make, valve yo kwagura igizwe n'umubiri, ipaki yo kumenya ubushyuhe n'umuyoboro wo kuringaniza
Uburyo bwiza bwo gukora bwa vali yo kwagura bugomba kuba uguhindura aho ifunguye mu gihe nyacyo no kugenzura umuvuduko w'amazi hamwe n'impinduka z'umutwaro w'ingufu. Ariko mu by'ukuri, bitewe n'uburyo ubushyuhe bwiyongera mu gipimo cy'ubushyuhe, igisubizo cya vali yo kwagura gihora buhoro buhoro. Iyo dushushanyije igishushanyo mbonera cy'igihe cy'ivali yo kwagura, tuzasanga atari umurongo ugororotse, ahubwo ari umurongo uzunguruka. Ubwiza bwa vali yo kwagura bugaragarira mu bunini bw'umuraba. Uko amplitude iba nini, ni ko imikorere ya vali igenda buhoro kandi ubwiza burushaho kuba bubi.
