Kodi Valavu ya Mpira ndi Chiyani?

A valavu ya mpiraAmalamulira kuyenda kwa madzi pogwiritsa ntchito mpira wozungulira wopanda kanthu wokhala ndi njira yoyendera madzi pakati. Zigawo zazikulu ndi izi:

- Thupi la valavu

- Mpira (wokhala ndi dzenje loboola bwino)

- Tsinde la valavu

- Mphete yotsekera

- Chogwirira/choyendetsera

Kuzungulira mpira pa 90° kumatsegula/kutseka njira yoyendera madzi. Ma valve a mpira amapereka kutseka kwabwino kwambiri komanso kugwira ntchito mwachangu, zomwe zimapangitsa kuti akhale abwino kwambiri pantchito zamafakitale.
