Valve ya overcenter(Hydraulic Balance Valve) ndi gawo lofunikira kwambiri la hydraulic. Ntchito yake ndikukwaniritsa kuwongolera kolondola mu hydraulic system, kukhalabe ndi mphamvu ya hydraulic system ndikuthana ndi zovuta zowongolera.
valavu ya overcenter (HydraulicBalanceValve) ndi yogwira ntchito kwambiri komanso yodalirika ya hydraulic component. Lili ndi ubwino wa kuthamanga kwa ntchito, kulondola kwambiri komanso kuchita bwino kwambiri. Amagwiritsidwa ntchito kwambiri pamakina omanga, kukumba makina, makina opusher, makina a thalakitala, makina amafuta amafuta ndi magawo ena.
Mfundo yogwira ntchito ya hydraulic balance valve ndi yakuti mu hydraulic system, pamene madzi amadzimadzi amadzimadzi akuyenda ku pistoni kumene valve yotsalira imayikidwa, pisitoni mkati mwa valve balance idzasinthidwa ndi kupanikizika kwa mkati, kotero kuti kuthamanga kufalikira. kuchokera kunja kwa sitiroko kupita mkati mwa sitiroko, kupangitsa ma hydraulic system Kukwaniritsa bwino. Pamene kupanikizika kumaposa mtengo wochuluka wokhazikitsidwa ndi valve balance, hydraulic flow flow idzasefukira, kusunga dongosolo la hydraulic pa mlingo wogwira ntchito bwino.
