kutseka pang'onopang'ono valavu ya flange
Valavu yoyang'ana makamaka imapangidwa ndi thupi la valve, ma discs awiri a semicircular valve, kasupe wobwerera, silinda yosungira mafuta, kutseka pang'onopang'ono banki yaing'ono ya singano (valve yowongolera ma valve), yomwe imakankhira ma discs awiri a valve bwino ndikukankhira kwa sing'anga yolowera. Pa nthawi yomweyo, sing'anga kuthamanga pa polowera amalowa m'munsi mwa pisitoni mu yamphamvu yosungirako mafuta kukankhira pisitoni, ndi mafuta kumtunda kwa pisitoni motsatana mbamuikha mu mchira mapeto a yamphamvu yaing'ono mbali zonse za valavu thupi kudzera singano valavu, kuti atalikitse pisitoni ndodo mu yamphamvu yaing'ono. Pamene kupanikizika kwa sing'anga yolowera kumatsika pansi pa kukakamizidwa pa malo otulukira Panthawiyi, chimbalecho chidzatseka chokha pansi pa masika ndi kubwerera kwapakatikati, koma chifukwa ndodo ya pisitoni ili pamalo otalikirapo. Dimba la valve silingathe kutsekedwa kwathunthu, ndipo pafupifupi 20% ya malowa amasiyidwa kuti sing'anga idutse, yomwe imagwira ntchito yochotsa nyundo.
