Iwo akatevedzana ari kaviri overcenter mavharuvhu. Kuburikidza nemavharuvhu aya zvinokwanisika kugadzirisa mitoro yebidirectional, kuvimbisa kugadzikana munzvimbo yekushanda uye kudzora mafambiro avo kunyangwe pamberi pemitoro inokwevera isingakonzereki. Muviri wevharuvhu une kaviri Cetop 3 flanging unobvumira mavharuvhu aya kuti ashandiswe muma hydraulic masisitimu akavakirwa paCetop 3, achiamisa pakati pe modular base uye inotungamira solenoid vharafu. Iyo yakanyanya kudzvinyirira kushanda ndeye 350 bar (5075 PSI) uye iyo yakanyanya kukurudzirwa kuyerera mwero ndeye 40 lpm (10,6 gpm).

Movement control inoitika nekuda kwekuvhurwa zvishoma nezvishoma kweiyo actuator re-yekupinda mutsara, iyo inotungamirwa neiyo hydraulic piloting kune yakatarisana uye iyo inoburitsa kumashure kumanikidza kunokwana kuyera kumhanya kwekufamba kweactuator kunyangwe pamberi pe giravhiti mutoro, nokudaro kudzivirira kuitika kwechiitiko chinonzi cavitation.

VBCS counterbalance valves inogonawo kuita basa re anti-shock valve, kuchengetedza hydraulic system uye mechanical structure iyo yakabatanidzwa kubva kune chero ipi zvayo yekumanikidzika inogona kuitika nekuda kwekuremerwa kwakanyanya kubva kune njodzi. Iri basa rinogoneka chete kana mutsara wekudzoka kuzasi kwevharuvhu wakabatana netangi. VBCS ivhavha isina kubhadharwa inopikisa: chero ipi zvayo yekudzokera shure inowedzerwa kugadziriro yevhavha uye inopesana nekuvhura. Kune rudzi urwu rwevhavha saka inokurudzirwa kushandisa muzvirongwa zvinosanganisira cetop directional valve ine open center spool, nevashandisi vanobatanidzwa kuti vabudise munzvimbo isina kwayakarerekera.

Kunyanya kutarisirwa kunotorwa neVBCS mukuvaka uye kuvimbiswa kwezvikamu zvemukati zvinoona hydraulic seal, verifying dimensions uye geometric tolerances, pamwe chete nechisimbiso pachayo kana valve yaungana. Muviri uye zvikamu zvekunze zvakagadzirwa nesimbi yakasimba-yakasimba uye inodzivirirwa kubva pakuora ne zinc plating. Iyo machining yemuviri pane zvinhanho zvitanhatu inovimbisa kuita kwakaringana kwekurapa kwepamusoro kune mukana wekubudirira kwayo.

Pazvikumbiro zvakafumurwa kune zvinokuvadza zvakanyanya (semuenzaniso zvikumbiro zvemugungwa) mushonga we zinc-nickel unowanikwa pakukumbira. Yakasiyana yekuseta mareshi uye akasiyana pilot ratios aripo kuti agadzirise zvirinani kune ese marudzi ekushandisa. Kushandisa chivharo chepurasitiki zvinokwanisikawo kuisa chisimbiso chekugadzirisa, kuchidzivirira kubva pakukanganisa. Nokuda kwekushanda kwakanyatsonaka zvinokurudzirwa kuisa vheji yekupikisa pamutengo we 30% yakakwirira kudarika basa guru rekushanda.
