Mavavu a DBD ochepetsa kuthamanga ndi ma valve a poppet omwe amagwiritsidwa ntchito mwachindunji. Amagwiritsidwa ntchito kuchepetsa kupanikizika mu hydraulic system. Ma valve makamaka amakhala ndi manja, masika. poppet yokhala ndi damping spool (magawo opanikizika 2.5 mpaka 40 MPa) kapena mpira (kupanikizika siteji 63 MPa) ndi chinthu chosinthira. Kuyika kwa kupanikizika kwadongosolo kumasinthasintha mopanda malire kudzera pa chinthu chosinthira. Masika amakankhira poppet pampando. Njira ya P imalumikizidwa ku dongosolo. Kupanikizika komwe kulipo mu dongosolo kumagwiritsidwa ntchito kumalo a poppet (kapena bail)

Ngati kupanikizika mu njira P kukwera pamwamba pa valve yomwe imayikidwa pa kasupe, poppet imatsegulidwa motsutsana ndi kasupe. Tsopano kuthamanga kwamadzimadzi kumayenda kupanga njira P mu tchanelo T. Kugunda kwa poppet kumachepetsedwa ndi pini. Kuti mukhalebe ndi mphamvu zoyendetsera bwino pamtundu wonse wa kuthamanga kwamtundu uliwonse wamtunduwu umagawidwa m'magawo 7. Gawo limodzi loponderezedwa limafanana ndi kasupe wina wake kuti azigwira ntchito kwambiri zomwe zitha kukhazikitsidwa nazo.
