Ivalve engaphezulu(I-Hydraulic Balance Valve) yinto ebaluleke kakhulu ye-hydraulic component. Umsebenzi wayo kukufezekisa ulawulo oluchanekileyo kwi-hydraulic system, ukugcina ibhalansi ye-hydraulic system kunye nokuxazulula iingxaki zokulawula eziyinkimbinkimbi.
ivalve engaphezulu (i-HydraulicBalanceValve) yinto esebenza ngokufanelekileyo kwaye ithembekileyo ye-hydraulic component. Ineenzuzo zoxinzelelo oluphezulu lokusebenza, ukuchaneka okuphezulu kunye nokusebenza kakuhle. Isetyenziswa kakhulu koomatshini bokwakha, ukugrumba oomatshini, oomatshini bokutyhala, oomatshini betrektara, oomatshini bepetroleum kunye namanye amacandelo.
Umgaqo osebenzayo we-valve ye-hydraulic balance kukuba kwinkqubo ye-hydraulic, xa i-hydraulic fluid igeleza kwi-piston apho i-valve ye-balance ifakwe khona, i-piston ngaphakathi kwe-valve yokulinganisa iya kulungiswa ngoxinzelelo lwangaphakathi, ukwenzela ukuba uxinzelelo luhanjiswe. ukusuka ngaphandle kwe-stroke ukuya ngaphakathi kwe-stroke, ukwenza inkqubo ye-hydraulic ifezekise ibhalansi. Xa uxinzelelo ludlula ixabiso eliphezulu elibekwe yi-valve yebhalansi, ukuhamba kwe-hydraulic kuya kuphuphuma, ukugcina inkqubo ye-hydraulic kwinqanaba elikhuselekileyo lokusebenza.
