1. Chimbale chavalavu yokhala ndi mphiraimakhala yooneka ngati diski ndipo imazungulira tsinde lozungulira la valavu. Chifukwa njira mu valavu ndi streamlined, kukana kuyenda ndi yaying'ono kuposa agulugufe mtundu valavu. Valavu yoyang'ana gulugufe imagawidwa kukhala mtundu umodzi wa disc, mtundu wamtundu wapawiri ndi theka la mtundu wachitatu, mitundu itatuyi imagawika makamaka molingana ndi m'mimba mwake ya valve, cholinga chake ndikuletsa sing'anga kuyimitsa kutuluka kapena kubwereranso, kufooketsa mphamvu ya hydraulic.
2, Valavu yoyang'ana mphira: valavu ya valve ikuyendayenda pakatikati pa mzere wa valve body check valve, phokoso loyang'ana phokoso likhoza kuikidwa pa chitoliro chopingasa, mu mpira wothamanga kwambiri wa caliber check valve ungagwiritsidwe ntchito mpira. Maonekedwe a thupi la valve yochepetsera phokoso ndi yofanana ndi ya valavu yapadziko lonse (ikhoza kukhala yapadziko lonse lapansi ndi valavu ya globe), kotero kuti mphamvu yake yotsutsa madzi ndi yaikulu. Mapangidwe ake ndi ofanana ndi valavu yapadziko lonse lapansi, ndipo thupi ndi disc ndizofanana ndi valavu yapadziko lonse lapansi. Kumtunda kwa diski ndi kumunsi kwa chivundikiro cha valve kumakonzedwa ndi manja otsogolera, ndipo chiwongolero cha disc chikhoza kukwezedwa ndikutsitsa momasuka mu kalozera kapu ya valve. Pamene sing'anga ikuyenderera, diski imatsegulidwa ndi kukankhira kwapakatikati, ndipo pamene sing'anga imasiya kuyenda, diski ya valve imagwera pampando pambali yowongoka kuti zisawonongeke. Kuwongoka kupyolera mu gulugufe cheke valavu sing'anga polowera ndi kutulukira njira njira ndi mpando njira njira perpendicular; Valavu yokweza yoyima, njira yolowera ndi njira yotulutsiramo ndi njira yapampando ndi yofanana, kukana kwamayendedwe ndikocheperako kuposa mowongoka.
3. Valavu yoyang'ana mphira: valavu ya valve imayenda pakati pa mzere wapakati wa thupi la valve.valavu yowunika mtundu wa chitolirondi valavu yatsopano, kukula kwake kochepa, kulemera kwake, teknoloji yabwino yopangira, ndi imodzi mwa njira zachitukuko za valavu. Koma mphamvu yokoka yamadzimadzi ndiyokulirapo pang'ono kuposa ya mavavu a swing cheque.
