Ama-valve okusiza ukucindezela kwe-DBD ama-valve e-poppet asebenza ngokuqondile.Asetshenziselwa ukukhawulela ukucindezela ohlelweni lwe-hydraulic. Ama-valve ngokuyinhloko ahlanganisa umkhono, intwasahlobo. i-poppet ene-damping spool (izigaba zokucindezela 2.5 kuya ku-40 MPa) noma ibhola (isiteji sokucindezela 63 MPa) kanye nesici sokulungisa. Ukusetha kwengcindezi yesistimu kuyashintshashintsha ngokungenamkhawulo nge-elementi yokulungisa.Intwasahlobo iphushela i-poppet esihlalweni. Isiteshi esingu-P sixhunywe ohlelweni.Ingcindezi ekhona ohlelweni isetshenziswa endaweni ye-poppet (noma ibheyili)

Uma ingcindezi esiteshini P ikhuphuka ngaphezu kwe-valve ebekwe entwasahlobo, i-poppet ivula ngokumelene nentwasahlobo. Manje uketshezi olucindezelayo lugeleza lwakha isiteshi esingu-P kusiteshi T. Ukushaywa kwe-poppet kunqunyelwe iphini. Ukuze kugcinwe izilungiselelo ezinhle zokucindezela phezu kwalo lonke uhla lokucindezela uhla lokucindezela luhlukaniswa ngezigaba zokucindezela ezingu-7. Isiteji esisodwa sokucindezela sihambisana nentwasahlobo ethile yokucindezela okukhulu kokusebenza okungenzeka kusethwe nayo.
