Choyamba, mapangidwe a vavu agulugufe ndi osavuta kugwiritsa ntchito komanso osavuta kugwiritsa ntchito ndikuwongolera. Mapangidwe ake apadera a gudumu lamanja amalola ogwiritsa ntchito kusinthana mosavuta ndikusintha magwiridwe antchito popanda kugwiritsa ntchito zida zapadera kapena luso. Kuonjezera apo, valve imagwiritsa ntchito zipangizo zamakono komanso njira zopangira kuti zitsimikizire kuti zimakhala zokhazikika komanso zodalirika.

Kachiwiri, valavu yagulugufe yachitsulo chosapanga dzimbiri imakhala ndi ntchito yabwino yosindikiza komanso kusintha kolondola. Kugwiritsa ntchito kwake mkati mwa zida zapadera zosindikizira ndi kapangidwe kake, kumatha kuteteza bwino kutulutsa mpweya, ndikuonetsetsa kuti mpweya ukuyenda bwino komanso wofanana. Panthawi imodzimodziyo, valve imakhalanso ndi mphamvu zambiri zosinthira, zomwe zingathe kusinthidwa molondola malinga ndi kufunikira kwenikweni kwa kuyenda ndi kupanikizika.
