Amavalvu e-overcenter eyodwa ochungechunge aklanyelwe ukuqinisekisa ukuzinza endaweni yokusebenza ye-hydraulic actuator enomthwalo omisiwe, kanye nokulawula ukunyakaza kwayo ohlangothini olulodwa kuphela (ngokuvamile isigaba sokwehla), okushiya uhlangothi oluphambene namandla okugeleza okukhululekile; ngenxa yamachweba anentambo ye-BSPP-GAS, ingafakwa kumugqa ohlelweni lwe-hydraulic.

Ngokuphakela ulayini obhekene nomthwalo, ulayini womshayeli ulawula ukuvuleka kwengxenye yesiteshi sokwehla okuvumela ukulawula ukunyakaza kwe-actuator futhi kugwenywe ukwenzeka kwe-cavitation ngenxa yesenzo sokuqhathanisa amandla adonsela phansi. Imbobo elinganiselwe ithobisa isignali yomshayeli ukuze ivalvu ivuleke futhi ivaleke ngokulinganayo, igwema ukuzungeza komthwalo. I-valve   yodwa ye-overcenter iphinda isebenze njenge-valve evimbela ukuthuthumela lapho kukhona iziqongo zokucindezela okubangelwa imithelela noma imithwalo eyeqile. Ukuze lokhu kwenzeke, umugqa wokubuyisela kumsabalalisi kufanele uxhunywe ku-drain. I-valve enxeshezelwe kancane: izingcindezi eziyinsalela emugqeni wokubuyisela awazithinti ukumiswa kwevalvu ngenkathi zinyusa amanani okuhlola.

Ngakho-ke ukusetshenziswa kwalolu hlobo lwe-valve kungenzeka ezinhlelweni ezine-DCV ezine-spool ephakathi nendawo evaliwe. I-hydraulic leakproof iyisici esibalulekile samavalvu angaphezulu. Ukuze kuqinisekiswe ukusebenza okuhle kakhulu, i-Oleoweb ikhiqiza izingxenye zangaphakathi zama-valve ayo ngensimbi enamandla amakhulu, eqinile futhi egayiwe, futhi, ngesikhathi senqubo yokukhiqiza, ihlola ngokucophelela ubukhulu nokubekezelelana kwejometri kwezakhi zokuvala, kanye nophawu ngokwalo. i-valve ehlanganisiwe.   ama-valve ezingxenye-emzimbeni: zonke izakhi zifakwe ngaphakathi kwe-hydraulic manifold, isisombululo esivumela ukuphatha amazinga okugeleza okuphezulu ngenkathi kukhawulwa ubukhulu obuphelele.

I-manifold yenziwe ngensimbi yokucindezela kokusebenza kuze kufike ku-350 bar (5075) nokumelana nokugqoka okuphezulu; ivikelwe ekugqwaleni ngokwelashwa kwe-zinc plating futhi yenziwa ngomshini ebusweni obuyisithupha ukuze kwenziwe ukwelashwa okungaphezulu okuyimpumelelo. Ngezinhlelo zokusebenza ezichayeke kuma-ejenti adlayo anamandla (isb. izicelo zasolwandle) Ukwelashwa kwe-Zinc-Nickel kuyatholakala uma ucelwa. Amavaluvu atholakala ngosayizi BSPP 3/8" kanye ne-BSPP 1/2” kumazinga okugeleza anconyiwe okufika ku-60 lpm (15,9 gpm). Izinkambu zokulinganisa ezihlukene nezilinganiso zomshayeli. Ukuze usebenze kahle, kunconywa ukuthi usethe i-overcenter. ama-valve anenani elingama-30% ngaphezu komthwalo omkhulu wokusebenza.
