Valavu yoyesera ndi valavu yomwe zigawo zake zotsegulira ndi kutseka ndi ma disc, zomwe chifukwa cha kulemera kwawo komanso kuthamanga kwa ntchito zimaletsa cholumikiziracho kuti chisabwererenso. Ndi valavu yodziyimira yokha, yomwe imatchedwanso valavu yodzipatula, valavu yobwerera, valavu yolowera njira imodzi, kapena valavu yoyesera. Mtundu wokweza ndi mtundu wozungulira ndi magulu awiri omwe diski imatha kusuntha.

Chitsinde cha valavu chomwe chimayendetsa diski mu valavu yozungulira ndi chokwezavalavu yoyezeraali ndi kapangidwe kofanana. Cholumikizira chimalowa kudzera m'mbali yolowera pansi ndikutuluka kudzera m'mbali yotulukira pamwamba (mbali yapamwamba). Valavu imatsegulidwa pamene mphamvu yolowera ipitirira kulemera konse kwa diski ndi kukana kwake kuyenda. Valavu imatsekedwa pamene cholumikizira chikuyenda mbali ina.

Ntchito ya valavu yoyezera kukweza ndi yofanana ndi ya valavu yoyezera kugwedezeka chifukwa zonsezi zimaphatikizapo mbale zozungulira za swash. Pofuna kuletsa madzi kuti asayende mmbuyo, mavalavu oyezera nthawi zambiri amagwiritsidwa ntchito ngati mavalavu apansi pazida zopopera. Ntchito yodzipatula yachitetezo ikhoza kuchitika kudzera mu kuphatikiza kwa valavu yoyezera ndi valavu yozungulira. Kukana kwambiri komanso kutseka kosakwanira kukatsekedwa ndi vuto.

Mu mizere yotumikira machitidwe othandizira komwe kupanikizika kungakwere pamwamba pa kupanikizika kwa dongosolo,ma valve owunikiraMa valve oyesera ozungulira ndi ma valve oyezera okweza ndi mitundu iwiri yayikulu ya ma valve oyezera. Ma valve oyezera ozungulira amazungulira pakati pa mphamvu yokoka (kusuntha motsatira mzere).

Ntchito ya valavu iyi ndikuletsa kuyenda kwa sing'anga kupita mbali imodzi pomwe ikuletsa kuyenda mbali ina. Vavu iyi nthawi zambiri imagwira ntchito yokha. Disiki ya valavu imatseguka pamene kuthamanga kwa madzi kukuyenda mbali imodzi; pamene kuthamanga kwa madzi kukuyenda mbali ina, mpando wa valavu umakhudzidwa ndi kuthamanga kwa madzi ndi kulemera kwa valavu, zomwe zimatseka kuyenda.

Gulu la ma valve awa limaphatikizapo ma valve owunikira, monga ma valve owunikira ozungulira ndi kukwezama valve owunikiraChidebe chooneka ngati chitseko cha valavu yoyezera swing chimatsamira bwino pamwamba pa mpando wotsetsereka chifukwa cha hinge mechanism. Valvu yotsekera imapangidwa mu hinge mechanism kotero kuti imakhala ndi malo okwanira ozembera ndipo imatha kukhudzana kwathunthu ndi mpando wa valve clack kuti zitsimikizire kuti nthawi zonse imatha kufika pamalo oyenera pamwamba pa mpando.

Kutengera ndi momwe zimagwirira ntchito, ma disc amatha kupangidwa ndi chitsulo chonse kapena kukhala ndi zikopa, rabala, kapena zophimba zopangidwa ndi chitsulocho. Kupanikizika kwa madzi kumakhala kopanda choletsa chilichonse valavu yowunikira swing yatsegulidwa kwathunthu, motero kutayika kwa kuthamanga kudzera mu valavu kumakhala kochepa.

Malo otsekera a mpando wa valavu pa thupi la valavu ndi komwe kuli diski ya valavu yoyezera kukweza. Valvu yotsalayo ndi yofanana ndi valavu yozungulira, kupatulapo kuti diskiyo imatha kukwera ndikugwa momasuka. Ngati pali kuyenda kwa medium, valavu imabwerera ku mpando wa valavu, ndikudula madzi. Kupanikizika kwamadzimadzi kumakweza valavu kuchokera pamwamba pa mpando wa valavu. Disikiyo ikhoza kupangidwa ndi chitsulo chokha, kapena ikhoza kukhala ndi mphete za rabara kapena ma pad olowetsedwa mu chimango cha diski, kutengera momwe imagwiritsidwira ntchito.

Valavu yoyezera kukweza ili ndi njira yopapatiza yamadzimadzi kuposa valavu yoyezera kugwedezeka, zomwe zimapangitsa kuti kuthamanga kwa mpweya kuchepe kwambiri kudzera mu valavu yoyezera kukweza komanso kuti madzi ayambe kuyenda pang'onopang'ono.
