Mavavu a single overcenter a   mndandanda amapangidwa kuti atsimikizire kukhazikika kwa malo ogwirira ntchito a hydraulic actuator yokhala ndi katundu woyimitsidwa, ndikuwongolera kusuntha kwake kumbali imodzi yokha (kawirikawiri gawo lotsika), kusiya mbali ina yoyendetsedwa ndi kuyenda kwaulere; chifukwa cha madoko a BSPP-GAS, imatha kukhazikitsidwa pamzere mu hydraulic system.

Podyetsa mzere moyang'anizana ndi katundu, woyendetsa ndegeyo amayang'anira kutsegula pang'ono kwa njira yotsika yomwe imalola kuyendetsa kayendedwe ka actuator ndikupewa zochitika za cavitation chifukwa cha kusiyanitsa mphamvu yokoka. Bowo lolinganizidwa limatsitsa chizindikiro choyendetsa kuti valavu itseguke ndikutseka molingana, kupewa kutsika kwa katundu. Vavu ya   single overcenter imagwiranso ntchito ngati valavu yoletsa kugwedezeka pakakhala kukwera kwamphamvu komwe kumachitika chifukwa champhamvu kapena kulemedwa kwambiri. Kuti izi zitheke, mzere wobwerera kwa wogawa uyenera kulumikizidwa ndi kukhetsa. The  ndi valavu yolipiridwa pang'ono: kukanikiza kotsalira pamzere wobwerera sikukhudza makonzedwe a valavu pamene kumawonjezera mayendedwe oyendetsa.

Kugwiritsiridwa ntchito kwa mtundu uwu wa valavu kotero n'kotheka mu machitidwe omwe ali ndi DCV ndi spool yotsekedwa pakati. Ma hydraulic leakproof ndi chinthu chofunikira kwambiri pamavavu opitilira muyeso. Pofuna kuonetsetsa kuti ntchito yabwino, Oleoweb imapanga zigawo zamkati za ma valve ake muzitsulo zamphamvu kwambiri, zowumitsidwa ndi kupukutidwa, ndipo, panthawi yopanga, imayang'anitsitsa miyeso ndi kulolerana kwa geometric kwa zinthu zosindikizira, komanso chisindikizo chokha. valavu yophatikizidwa.   ndi ma valve m'thupi: zigawo zonse zimayikidwa mkati mwa ma hydraulic manifold, yankho lomwe limalola kuyendetsa kuthamanga kwambiri ndikuchepetsa miyeso yonse.

Zobweza zambiri zimapangidwa ndi zitsulo zogwirira ntchito mpaka 350 bar (5075) ndi kukana kwambiri kuvala; imatetezedwa ku dzimbiri ndi chithandizo cha zinc plating ndipo imapangidwa pankhope zisanu ndi imodzi kuti ipangitse bwino chithandizo chapamwamba. Pazogwiritsa ntchito zokhala ndi zinthu zowononga kwambiri (monga zapamadzi) Chithandizo cha Zinc-Nickel chilipo mukafunsidwa. Mavavu akupezeka mu makulidwe a BSPP 3/8" ndi BSPP 1/2” pamiyezo yovomerezeka yogwirira ntchito mpaka 60 lpm (15,9 gpm). Magawo osiyanasiyana owongolera ndi mawonedwe oyendetsa. Kuti mugwire bwino ntchito, tikulimbikitsidwa kukhazikitsa chowongolera. mavavu kuti mtengo 30% apamwamba kuposa pazipita ntchito katundu.
