The loko wapangidwa engineering pulasitiki ABS ndi zosapanga dzimbiri lokhoma lamba;
Yoyenera valavu ya pulagi yamanja yokhala ndi 1 ″-8″;
Kugwiritsa ntchito bwino kwa valve yomwe imakhala yovuta kutseka;
Chokhazikika, chosawonongeka, chophatikizika komanso chosavuta. Chotsekera valavu chokhala ndi kukula koyenera chiyenera kusankhidwa.
Yezerani miyeso kuchokera ku A mpaka B, ndiko kuti, kukula kwa ndodo ya valve, ndiyeno sankhani loko yoyenera ya valavu malinga ndi kukula kwa ndodo ya valve.Ndikosavuta kwambiri kutsegulanso valavu.
Ngati wrench yogwirira ntchito ndi ndege ya ndodo ya valve pamwamba pa bokosi lotseketsa ingakhale ikugwirabe ntchito, maziko ndi chotchinga cha loko ya valavu zitha kusiyidwa pa valavu kuti ikhale yoyimilira.Panthawiyi, valavu ikhoza kutsegulidwa malinga ngati chivundikiro cha plug valve cha bokosi la lock chichotsedwa.
