Valve ya solenoid ni mtundu wa chipangizo cha electromechanical icho ŵakugwiliskira ntchito pakulaŵilira umo maji ghakuchitira, nga ni mphepo, maji, panji gasi. Lili na soleonid, iyo ni coil iyo yikupangika na magesi, na nthowa ya vavu. Para magesi ghakuŵikika pa solenoid, ghakupanga magnetic field agho ghakusuntha plunger panji armature, kujura panji kujara vavu kuti ghalongozge umo maji ghakuchitira.
Valve ya solenoid ya pneumatic ni mtundu unyake wa vavu ya solenoid iyo yikupangika kuti yigwiriskike nchito na ndondomeko za pneumatic, izo zikukhwaskana na kugwiliskira nchito mphepo yakufinyikizgika. Kupambana kwakuzirwa kuli mu mtundu wa maji agho ŵakukhumba kuti ŵawulongozge. Nangauli vavu ya solenoid yakumanyikwa yingagwiliskirika nchito pa maji ghakupambanapambana, vavu ya pneumatic solenoid yikupangika mwakupambanapambana kuti yiŵe na mphepo panji mphepo zinyake zakufinyikizgika.
Mukudumura, mavavu gha pneumatic solenoid ni mavavu gha solenoid, kweni ni mavavu gha solenoid ghose yayi ni mavavu gha pneumatic solenoid. Kupambana uku kukuthemba pa kugwiriskira ncito uko kukukhumbikwa na mtundu wa maji (pneumatic panji vinyake) kuti vavu yikupangika kuti yilongozge.
