Valavu ya mpira inachokera ku valavu yolumikizira. Ili ndi kayendedwe kofanana ka madigiri 90, koma kusiyana kwake ndikuti valavu ya mpira ndi bwalo lozungulira lomwe lili ndi dzenje lozungulira kapena njira yodutsa mu mzere wake. Chiŵerengero cha pamwamba pa bwalo ndi kutsegula kwa njira chiyenera kukhala chofanana, ndiko kuti, pamene mpirawo ukuzungulira madigiri 90, malo onse ozungulira ayenera kukhalapo pakhomo ndi potulukira, motero kudula kuyenda. Valavu ya mpira ikhoza kutsekedwa mwamphamvu ndi kuzungulira madigiri 90 okha ndi mphamvu yaying'ono. Mphepete mwa valavu yofanana kwathunthu imapereka njira yolunjika yoyendera popanda kukana kwakukulu kwa sing'anga.
Kawirikawiri amakhulupirira kuti valavu ya mpira ndi yoyenera 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 komanso kukonza, koyenera kugwiritsidwa ntchito pazinthu zonse monga madzi, zosungunulira, asidi ndi gasi wachilengedwe, komanso koyenera pazinthu zomwe zimakhala zovuta kugwira ntchito, monga mpweya, hydrogen peroxide, methane ndi ethylene. Thupi la valavu ya mpira likhoza kukhala logwirizana kapena losakanikirana.
