(2) Makina a solenoid valavu yatenthedwa. Wai waya wa sonnoid amatha kuchotsedwa ndikuyeza ndi gulu lamphamvu. Gawo litatsegulidwa, malo opangira solenoid adzawotcha.
Zifukwa zake zimaphatikizapo comp coil, osauka otchinga ndi maginito otayira, zomwe zimapangitsa kuti coil yochulukirapo pano ndikuyatsa. Chigwa cha solenoid ndiokwera mtengo, motero ndikofunikira kuti madzi amvula asalowe nawo valavu. Kuphatikiza apo, ngati kasupe ndi wovuta kwambiri, mphamvu zake ndizazikulu kwambiri, kuchuluka kwa chiwerengerocho ndi chochepa kwambiri, ndipo mphamvu yoyamwa sikokwanira.
