Udindo wa 2 kapena 2 njira ya solenoid solekoid nthawi zambiri amakhala otsekedwa, kugwirira ntchito ma valve a solenoid ndipo safuna kukakamizidwa kochepa kuti mugwiritse ntchito. Monga taonera mu chithunzi chomwe chili pansipa, pomwe coil ndiye de {{3} Ngati coil imalimbikitsidwa (chojambula choyenera), Solenoid imakweza kakang'ono ndikulola kuti sing'anga wogwira ntchito kuti ayende mu orifice. Kuwongolera kwapakatikati ndi koyenda kumasonyezedwa kufiirira mu chithunzi.
