Kugonjetsa kukana kwa kasupe kumapangitsa kuti valavu ikhale yotseguka kapena yotseka.Pamene kupanikizika kwapakatikati kumapeto kwa cholowera kumakhala kotsika kuposa kolowera, valavu yoyang'ana yoyang'ana: chifukwa cha kupanikizika kwa sing'anga kumapeto kwa payipi.Kasupe amakankhira pachimake cha valve kumpando wa valve kuti atseke valavu, kuteteza sing'anga kuti isabwererenso, choncho imakhala ndi ntchito yosabwerera.Ma vertical check valves amagwiritsidwa ntchito kwambiri mu mankhwala, liquefied petroleum gasi, madzimadzi ndi mafakitale ena.Malinga ndi kapangidwe ka valavu cheke, akhoza kugawidwa mu mitundu itatu: kukweza valavu cheke, kukweza valavu cheke ndi valavu butterfly.
Valavu yomwe imagwiritsidwa ntchito poletsa sing'anga kuti isabwerere mmbuyo imatchedwanso valavu yoyendera, valavu yanjira imodzi, valavu yobwerera kumbuyo, ndi valavu yakumbuyo yakumbuyo.Valve yowunikira ndi mtundu wa valve yodziwikiratu, ntchito yake yayikulu ndikuletsa kutuluka kwapakati kwa sing'anga, kuteteza mpope ndi mota yoyendetsa kuti zisabwerere, komanso kutulutsa kwapakati pa chidebe.Ma valve owunika amathanso kugwiritsidwa ntchito popereka mapaipi pomwe kukakamiza kumatha kukwera kunjira yothandizira yomwe imapitilira kuthamanga kwa dongosolo.Ma valve owunikira amatha kugawidwa kukhala ma valve oyendera (ozungulira molingana ndi pakati pa mphamvu yokoka) ndikukweza ma valve (akuyenda mozungulira).Ntchito ya valavu yamtundu uwu ndikungolola kuti sing'anga ipite kumbali imodzi ndikuletsa kuyenda kwa njirayo.Kawirikawiri valavu yamtunduwu imangogwira ntchito pansi pa mphamvu yamadzimadzi yomwe ikuyenda kumbali imodzi, valavu ya valve imatsegula;pamene madzi amadzimadzi akuyenda mosiyana, kuthamanga kwamadzimadzi ndi kudzidzidzimutsa kwa valavu ya valve kumachita pampando wa valve, motero kumadula kutuluka.Pakati pawo, valavu yoyang'ana ulusi wamkati ndi valavu yoyang'ana yoyima imatanthawuza kutsegula ndi kutseka kwa valve clack malingana ndi kutuluka kwa sing'anga yokha.Ma valve olumikizidwa ndi ma valavu amtundu uwu, kuphatikiza ma valve oyendera ma cheki ndi ma valve okweza.Chovala choyang'ana cha swing chimakhala ndi makina ochezera apakati ndi ma disc a valve ngati chitseko chomwe chimakhazikika momasuka pamwamba pa mpando wokhazikika wa valve.Pofuna kuonetsetsa kuti phokoso la valve likhoza kufika pamalo oyenera a mpando wa valavu nthawi zonse, valavu ya valve imapangidwa mu makina a unyolo kuti valavu ikhale ndi malo okwanira kuti atembenuke ndipo imapangitsa kuti valavu ikhale yolimba komanso yogwirizana ndi mpando wa valve.Chovala cha valve chikhoza kupangidwa ndi chitsulo, chikopa, mphira, kapena chophimba chopangira chikhoza kuikidwa pazitsulo, malingana ndi zofunikira za ntchito.Pamene swing check valve yatsegulidwa kwathunthu, kuthamanga kwamadzimadzi kumakhala kosalekeza, kotero kuti kuthamanga kutsika kudzera mu valve kumakhala kochepa.Disiki ya valve ya valve yokweza valavu imakhala pamtunda wosindikizira wa mpando wa valve pa thupi la valve.Pokhapokha kuti diski ikhoza kukwezedwa ndikutsitsa momasuka, valavu yonseyi ili ngati valve yotseka.Kuthamanga kwamadzimadzi kumakweza diski kuchokera kumalo osindikizira a mpando wa valve, ndipo kubwerera kumbuyo kwa sing'anga kumapangitsa kuti diski ibwerere ku mpando ndikudula kutuluka.Malinga ndi momwe amagwiritsidwira ntchito, ma disc a valve amatha kukhala zitsulo zonse, kapena akhoza kukhala ngati mphira wa rabara kapena mphete ya mphira yomwe imayikidwa pa disk frame.Monga valavu yoyimitsa, njira yamadzimadzi kudzera muzitsulo zoyendetsa galimoto imakhalanso yopapatiza, kotero kuti kuthamanga kutsika kupyolera mu valavu yowunikira ndi yaikulu kuposa ya valavu yoyang'ana swing, ndipo kutuluka kwa valavu yowunikira kumakhala kochepa.

Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
