Mtundu wotsekedwa kapena mtundu wotseguka umatha kusankhidwa molingana ndi nthawi yopitilira yogwira ntchito.
1.
2. Nthawi yayitali yotsegulira ndi kutseka ndizofunikira, motero kudziyimira pawokha.
3. Mtundu wotseguka mtundu wa solekoid ndi woyenera kutsegulidwa komwe akufunika kutsegulidwa kwa nthawi yayitali, ndipo nthawi yotsegulira ndiyotalikirapo kuposa nthawi yotseka, ndipo nthawi yotseguka siyitali kwambiri.
4. Kutseguka kwa solenoid kumagwiritsidwa ntchito pakudulidwa kwadzidzidzi {{1} kuchokera ku Shenoleid valavu. Koma, nthawi zina, nthawi zambiri valavu ya solenoid singasankhidwe, monga ng'anjo yowunikira moto,
