Ma valve oyesera amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana. Mu makina operekera madzi,ma valve owunikiraamagwiritsidwa ntchito poletsa madzi kubwerera m'mbuyo komanso kusunga mphamvu ya madzi kukhala yolimba. Mu makampani opanga mankhwala, ma valve oyesera amaletsa kubwerera m'mbuyo kwa mankhwala oopsa m'mapaipi, motero amateteza zida ndi chitetezo cha ogwira ntchito.
