Igice cya powergate ni igice cyingufu zikoreshwa mugucunga umurizo wikamyo. Ikoresha imyanya ibiri-itatu-solenoid valve hamwe na electromagnetic cheque valve kugirango igaragaze ibikorwa nko guterura, gufunga, kumanuka, no gufungura umurizo kugirango urangize imizigo. Imirimo yo gupakurura no gupakurura. Umuvuduko wamanuka urashobora guhindurwa unyuze muri valve. Kubera ko ingufu zumurizo wumuduga zakozwe ubwazo, ifite ibiranga uburyo bworoshye bwo kuyishyiraho no kuyitunganya, no gukora byoroshye, kubwibyo ikwiriye gushyirwaho itambitse.
