Pali mapulani ambiri a valve, mitundu ndi mitundu, yomwe imagwiritsidwa ntchito kwambiri m'makampani. Zonse zimakwaniritsa ntchito imodzi kapena zingapo zomwe zili pamwambapa. Mavavu ndi zinthu zodula. Ndikofunika kutchula ma valve olondola a ntchitoyi, ndipo ayenera kukhala ndi deta yolondola yogwiritsira ntchito zakumwa.
