Valavu ya mpira imatha kutsekedwa bwino ndi kuzungulira kwa madigiri 90 okha komanso mphamvu yaying'ono. Mphepete mwa valavu yofanana kwathunthu imapereka njira yolunjika yoyendera popanda kukana kwambiri kwa sing'anga. Kawirikawiri amaganiziridwa kuti valavu ya mpira ndiyoyenera kwambiri kutsegula ndi kutseka mwachindunji, koma zomwe zachitika posachedwapa zapanga valavu ya mpira kuti igwire bwino ntchito ndikulamulira kuyenda kwa madzi. Chinthu chachikulu cha valavu ya mpira ndi kapangidwe kake kakang'ono, kosavuta kugwiritsa ntchito ndi kukonza, koyenera kugwiritsa ntchito zinthu zogwirira ntchito monga madzi, zosungunulira, asidi ndi gasi wachilengedwe, komanso koyenera kugwiritsa ntchito zinthu zogwirira ntchito zomwe zili ndi mikhalidwe yovuta yogwirira ntchito, monga mpweya, hydrogen peroxide, methane ndi ethylene. Thupi la valavu ya mpira likhoza kukhala logwirizana kapena lophatikizana.
Chisinthiko ndi mfundo yogwirira ntchito
Valavu ya mpira inachokera ku valavu yolumikizira. Ili ndi mphamvu yokweza yofanana ndi kuzungulira madigiri 90, koma kusiyana kwake ndikuti thupi la cock ndi bwalo lozungulira lomwe lili ndi dzenje lozungulira kapena njira yodutsa mu mzere wake. Chiŵerengero cha bwalo lozungulira ndi kutsegula kwa njira chiyenera kukhala chakuti bwalo likazungulira madigiri 90, mabwalo onse ayenera kuwonekera pakhomo ndi potulukira, motero amaletsa kuyenda kwa madzi.
