Zotsatizanazi ndi mavavu awiri owonjezera. Kupyolera mu ma valves ndizotheka kuyendetsa katundu wa bidirectional, kutsimikizira kukhazikika pa malo ogwira ntchito ndi kulamulira kayendetsedwe kawo ngakhale pamaso pa zolemetsa zomwe sizimapanga kupanikizika. Thupi la valavu lomwe lili ndi ma Cetop 3 flanging awiri limalola kuti ma valvewa agwiritsidwe ntchito pamakina a hydraulic kutengera Cetop 3, kuwayika pakati pa modular base ndi valavu yolowera solenoid. Kuthamanga kwakukulu kogwira ntchito ndi 350 bar (5075 PSI) ndipo mlingo woyenera kwambiri wothamanga ndi 40 lpm (10,6 gpm).
Kuwongolera kwamayendedwe kumachitika chifukwa cha kutsegulidwa kwapang'onopang'ono kwa mzere woloweranso wa actuator, womwe umayendetsedwa ndi hydraulic piloting mbali inayi ndipo kumapangitsa kuti kumbuyo kukhale kokwanira kuwongolera kuthamanga kwa actuator ngakhale pamaso pa mphamvu yokoka, motero kupewa kuchitika kwa chodabwitsa chotchedwa cavitation.
Ma valve otsutsana ndi VBCS amathanso kugwira ntchito ya anti-shock valve, kuteteza ma hydraulic system ndi makina opangidwa ndi makina omwe amagwirizanitsidwa ndi nsonga zamtundu uliwonse zomwe zingachitike chifukwa cha katundu wochuluka kuchokera ku zochitika mwangozi. Ntchitoyi ndi yotheka pokhapokha ngati mzere wobwerera pansi pa valve ukugwirizana ndi thanki. VBCS ndi valavu yosalipidwa yotsutsana: zopinga zilizonse zimawonjezeredwa ku makonzedwe a valve ndikutsutsa kutsegula. Kwa mtundu uwu wa valve ndiye akulimbikitsidwa kuti agwiritse ntchito machitidwe omwe amaphatikizapo valavu ya cetop directional valve ndi spool yapakati yotseguka, ndi ogwiritsa ntchito omwe amalumikizidwa kuti atuluke m'malo osalowerera ndale.
Chisamaliro chapadera chimatengedwa ndi VBCS pomanga ndi kutsimikizira zigawo zamkati zomwe zimazindikira chisindikizo cha hydraulic, kutsimikizira miyeso ndi kulekerera kwa geometric, komanso chisindikizo chokha pamene valve imasonkhanitsidwa. Thupi ndi zigawo zakunja zimapangidwa ndi chitsulo champhamvu kwambiri ndipo zimatetezedwa kuti zisawonongeke ndi zinc plating. Kukonzekera kwa thupi pazigawo zisanu ndi chimodzi kumatsimikizira kuchitidwa bwino kwa mankhwala apamwamba kuti apindule bwino.
Pazifukwa zomwe zimakhudzidwa ndi zinthu zowononga kwambiri (monga zapamadzi) mankhwala a zinki-nickel amapezeka ngati afunsidwa. Mitundu yosiyanasiyana ya makonzedwe ndi mawonedwe osiyanasiyana oyendetsa amapezeka kuti agwirizane bwino ndi mitundu yonse ya mapulogalamu. Pogwiritsa ntchito kapu ya pulasitiki ndizothekanso kusindikiza zoikamo, kuziteteza kuti zisasokonezeke. Kuti mugwiritse ntchito bwino ndi bwino kuti muyike valve yotsutsana ndi mtengo wa 30% kuposa kuchuluka kwa ntchito.
