Vinthu vinandi ivyo vikupangika na mafakitale vikugwira ntchito na mavalvu gha solenoid mu mawonekero ghanandi na kukura ndipo ni mtundu wakwamba wa chigaŵa cha makina icho chikugwiriskirika nchito mu mitundu yose ya vipangizo, makina, na ndondomeko.
Mavalves gha solenoid electro elempain -mechanical ndondomeko kuti ŵaŵawovwire, kuŵawovwira kuti ŵalongozgeke kufuma ku malo ghakutali na awo ŵakugwira ntchito panji ndondomeko zakulongozgera, na kujura vinthu vinandi ivyo vingachitika.
Nthowa yimoza ya actuation ya mavavu yikugwiriskira ncito electro-mechanical solenoids kuti yigwirenge nchito mwaluŵiro panji mwambura kumanyikwa. Solenoid yakwamba yili na magesi ghakuzungulira, agho ghakuchemekaso coil, ghakuŵikika kuzingilizga chitsulo cha chisulo panji pisitoni iyo yikusunkhunyika, iyo yingaŵa ya spring - loaded. Para mphamvu yakulaŵilira—kanandi 12VDC, 24VDC, 24VAC, panji 120VAC pa vinthu vya mafakitale—yikugwiriskirika nchito, coil yikuŵa electromagnet ndipo yikusuntha mtima.
