Valavu yodziyendetsa yokha iyi ndi chitsulo chosapanga dzimbiri chopumira molingana ndi mphamvu yochepetsera valavu yopangidwira makamaka mapaipi a nthunzi omwe amakhala okhazikika komanso oyenda bwino. Zimagwiritsa ntchito zipangizo zachitsulo zosapanga dzimbiri, zomwe zimakhala ndi kukana kwa dzimbiri komanso kutentha kwapamwamba, ndipo zimatha kukhala zokhazikika m'madera osiyanasiyana ogwira ntchito.
Ntchito yayikulu ya valavu yowongolera iyi ndikukwaniritsa kukhazikika kokhazikika ndi kukhazikika mu mapaipi a nthunzi mwakusintha zokha kuthamanga kwake. Ikhoza kusintha yokha kutsegula kwa valve molingana ndi kusintha kwa nthunzi, kuonetsetsa kuti kuthamanga kwa nthunzi ndi kuthamanga kumakhala mkati mwazomwe zimayikidwa. Izi sizingangowonjezera mphamvu yogwiritsira ntchito nthunzi, komanso kupewa zovuta zachitetezo zomwe zimadza chifukwa cha kuthamanga kwambiri kapena kutsika.
Kuphatikiza apo, valavu yowongolera iyi imakhalanso ndi ntchito yochepetsera kuthamanga kwapakati. Ikhoza kuchepetsa kuthamanga kwa nthunzi yothamanga kwambiri kuti ikhale yotsika kwambiri kuti ikwaniritse zofunikira zosiyanasiyana za ntchito. Kuphatikiza apo, chiŵerengero chake chochepetsera mphamvu chimatha kusinthidwa ngati pakufunika, ndikupangitsa kuti ikhale yosavuta kugwiritsa ntchito.
Ponseponse, valavu yodziyendetsa yokhayi ndi yogwira ntchito kwambiri komanso yosavuta kugwiritsa ntchito zida zamapaipi a nthunzi, zomwe zitha kutenga gawo lofunikira pakupanga mafakitale komanso moyo wapakhomo.
