Ma valves solenoidNthawi zambiri amabwera m'mitundu iwiri yayikulu kutengera opaleshoni yawo:
Nthawi zambiri amatsegulidwa (ayi) solenoid valavu: Mu mtundu uwu, valavu imakhalabe yotseguka pomwe solenoid sinalimbikitsidwe. Pamene solenoid yatsegulidwa, imatseka valavu. Mauvuwa amagwiritsidwa ntchito ngati kutuluka kwa madzimadzi kumafunikira kuti chisasokoneze mpaka solenoid kumathandizidwa kuyimitsa.
Nthawi zambiri amatseka (nc) solenoid valavu: Mu mtundu uwu, valavu imatseka pomwe solenoid sinalimbikitsidwe. Pamene solenoid yatsegulidwa, imatsegula valavu kuti iloke madzi. Izi zimagwiritsidwa ntchito ngati kutuluka kwa madzimadzi kumafunikira kuyimitsidwa ndi kusakhazikika mpaka solenoid imathandizidwa kuti ilole.
Mitundu iyi imathanso kuphatikizidwanso mu mavamu ena kuti azisamalira zojambula zosiyanasiyana, mongaMwanjirakapena3-njiraMa valvels a solenoid, omwe amatchulapo madoko otuluka madzi.
