Mavavu opangira zipata ndivalavu yachipata chachitsulondi zitsanzo zabwino za mavavu a pachipata okhala ndi zinthu zotsatirazi.
Choyamba,valavu yachipata chachinyengondi ma valve opangidwa ndi zitsulo zopangira zipata amapangidwa pogwiritsa ntchito njira yopangira mphamvu zambiri, choncho amakhala ndi mphamvu yotsutsa kwambiri. Mavavu opangidwa ndi zinthu izi amatha kupirira kutentha kwambiri komanso kutentha kwambiri, ndipo ndi oyenera kugwiritsa ntchito mafakitale omwe amafunikira kuthamanga kwambiri, monga mafakitale amafuta, mafuta, ndi gasi.
Kachiwiri, ma valve opangidwa ndi globe ndi ma valve opangidwa ndi zitsulo zopangapanga amakhala ndi ntchito yabwino yosindikiza. Mapangidwe apangidwe ndi kusankha kwa zinthu za valve kumatsimikizira kuti chisindikizo cholimba ndikuteteza bwino kutayikira kulikonse. Kusindikiza kodalirika kumeneku kumapangitsa kuti valavu yapadziko lonse lapansi ikhale yogwira ntchito bwino m'malo ovuta komanso kuteteza chitetezo cha mapaipi amadzimadzi.
Kuphatikiza apo, ma valve opangidwa ndi globe ndi ma valve opangidwa ndi zitsulo zachitsulo ali ndi mawonekedwe otsika okana. Mapangidwe amkati a valve ndi mapangidwe a njira zamadzimadzi amalola kuti madzi azitha kuyenda bwino, kuchepetsa kukana kuyenda. Izi sizimangowonjezera kuyendetsa bwino kwa dongosolo, komanso kumachepetsa kugwiritsa ntchito mphamvu ndi ndalama zogwiritsira ntchito.
