1. Valavu ndi yosavuta kugwiritsa ntchito, yosinthika komanso yodalirika pakuyenda;
2. Chipangizo cha valve flap ndi chosavuta kusamalira, mawonekedwe osindikizira ndi omveka, ndipo mphete yosindikizira ndi yabwino komanso yothandiza kusintha;
3. Mapangidwe apansi a thupi la valve amapangidwa ngati mtundu wapansi, thupi la valve ndi mtundu wa O;
4. M'kati mwa valavu muli mphete zotsekera zomwe sizingakokoloke komanso kuti musachite dzimbiri.Vavu ikatsegulidwa, imatha kuteteza thupi la valve kuti lisatsukidwe ndikuwonongeka ndi sing'anga.Mphete yosindikiza imayikidwa mwapadera kuti kuuma kwa pamwamba kufika pa HRC56-62, yomwe ili ndi ntchito zolimbana ndi ma Wear-resistant komanso dzimbiri;
5. Chivundikiro cha chisindikizo cha valve disc chikuwonekera ndi simenti ya carbide ikafunika, ndipo awiri osindikizirawo amatengera kusindikiza kwa mzere kuti atsimikizire kudalirika kwa chisindikizocho ndikupewa mabala.
