Mavavu gha Solenoidkanandi vikwiza mu mitundu yiŵiri yikuru mwakuyana na ntchito yawo:
Mwachizoloŵezi (NO) Valve ya Solenoid: Mu mtundu uwu, vavu yikukhala yakujulika apo solenoid yilije nkhongono. Para solenoid yagwira ntchito, yikujara vavu. Mavalvu agha ghakugwiriskirika nchito para maji ghakunjira mu maji ghakukhumbikwira kuti ghaleke kuphwanyika mpaka apo solenoid yileke kukhwaskika kuti yilekeske.
Mwakumanyikwa (NC) Valve ya Solenoid: Mu mtundu uwu, vavu yikukhala yakujalika para solenoid yilije nkhongono. Para solenoid yayamba nchito, yikujura vavu kuti maji ghajumphe. Ivi vikugwiriskirika nchito para maji ghakusunkhunyika ghakukhumbikwira kuti ghalekeskeke mwa kuŵika pa malo ghake m’paka apo solenoid yiŵe na nkhongono kuti yizomerezgeke.
Mitundu iyi yingasazgikaso mu mavalvu ghanyake kuti yichitenge vinthu vyakupambanapambana, nga ni .2- nthowaolo3- nthowamavalvu gha solenoid, agho ghakung’anamura unandi wa madowoko gha maji.
