Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo komanso kukulitsidwa kosalekeza kwa magawo ogwiritsira ntchito, chiyembekezo chogwiritsa ntchito ma coil a valve solenoid chikuchulukirachulukira. M'munda wamlengalenga, ma valve a solenoid amagwiritsidwa ntchito poyang'anira machitidwe ovuta monga mafuta opangira mafuta ndi ma hydraulic systems a ndege kuti atsimikizire chitetezo cha ndege. Pazida zankhondo, ma valavu a solenoid amagwiritsidwa ntchito kuwongolera zida, makina amagetsi agalimoto, ndi zina zambiri, kuti apititse patsogolo zida zankhondo. Kuphatikiza apo, pankhani ya mphamvu, makampani opanga mankhwala komanso kuteteza chilengedwe, ma valavu a solenoid amakhalanso ndi gawo lofunikira pakuwongolera kayendedwe ka mapaipi amafuta ndi gasi ndikuwongolera kayendedwe ka madzi. Ntchitozi sizimangowonetsa kusiyana ndi kusinthasintha kwa solenoid coil, komanso zimasonyeza malo ake ofunikira pa chitukuko chamakono cha mafakitale ndi chikhalidwe cha anthu.
