Kufotokozera mwatsatanetsatane valavu cheke:
Ma valve owunika ndi ma valve odzichitira okha, omwe amadziwikanso kuti ma cheke, ma valve a njira imodzi, ma valve obwerera kapena ma valve odzipatula.Kusuntha kwa disc kumagawidwa kukhala mtundu wokweza ndi mtundu wa swing.Valve yowunikira ndi yofanana ndi mawonekedwe a valve yotseka, koma ilibe tsinde la valve lomwe limayendetsa diski.Sing'anga imayenda kuchokera kumapeto (mbali yakumunsi) ndikutuluka kuchokera kumapeto (kumtunda).Pamene kulowetsedwa kolowera kumakhala kwakukulu kuposa kuchuluka kwa kulemera kwa diski ndi kukana kwake, valve imatsegulidwa.M'malo mwake, valavu imatsekedwa pamene sing'anga ikubwerera.Chovala choyang'ana cha swing chili ndi diski yomwe imapendekera ndipo imatha kuzungulira mozungulira, ndipo mfundo yogwira ntchito ndi yofanana ndi ya valve yokweza.Valve yowunikira nthawi zambiri imagwiritsidwa ntchito ngati valavu pansi pa chipangizo chopopera kuti madzi asabwererenso.Kuphatikizika kwa valavu ya cheki ndi valavu yoyimitsa kumatha kutenga gawo la kudzipatula kwachitetezo.Choyipa ndichakuti kukana ndi kwakukulu ndipo ntchito yosindikiza imakhala yoyipa ikatsekedwa.
