A DIDNLIK check valve ndi mtundu wosavuta kwambiri wa valavu yowongolera yomwe imagwiritsidwa ntchito m'makina a hydraulic. Ma valve owunika amayimitsa kutuluka kwamadzi kunjira imodzi ndikulola kuyenda kwaufulu kumbali ina. Amadziwikanso kuti ma valve osabwerera. Ma valve owunika atha kugwiritsidwa ntchito ngati ma valve odzaza, ma bypass valve, pre-tensioning kapena kuteteza zida za hydraulic motsutsana ndi kuthamanga kwamphamvu.
Ma valve ambiri amatchera masika ndipo amagwiritsa ntchito mpira kapena mbale kuti asindikize kutuluka kumbali imodzi. Ma valve owunika amapangidwa ndi mipando ndipo motero amatha kusiyanitsa mabwalo popanda kutayikira. Mipira, mbale, ma poppets kapena ma poppet okhala ndi zisindikizo zofewa amagwiritsidwa ntchito ngati zinthu zodzipatula.
Pali mtundu wapadera wa valavu yomwe imalepheretsa ma pistoni kapena ma cylinder plungers kuti asatsike ndikuyambitsa ngozi. Izi zimatchedwa valve rupture valve. Pamene mzerewo ukuphulika, kuthamanga kwa valve rupture valve kumawonjezeka kwambiri, kumayambitsa kutsika kwapakati. Izi zimapanga mphamvu yamphamvu pa mpira, yomwe idzatseke nthawi yomweyo.
Mitundu ina yapadera ya ma check valves ndi ma valve oyendetsa oyendetsa ndege ndi ma shuttle valves. Valavu yoyendera yoyendetsedwa ndi woyendetsa imalola kuyenda kumbali iliyonse pogwiritsa ntchito chizindikiro champhamvu cha woyendetsa wakunja. Valve ya shuttle imalola kuyenda kwaulere pamagetsi othamanga kwambiri.
