Agasanduku ka valve ntarengwa, nanone bita Valve Position Monitor cyangwa ingendo ya valve, ni igikoresho gikoreshwa mugushakisha no kugenzura gufungura no gufunga umwanya wa valve. Igabanijwemo ubwoko bwa mashini na hafi. icyitegererezo cyacu gifite Fl-2n, Fl-3n, Fl-4n, Fl-5n. Umupaka uhindura agasanduku guturika-kurinda no kurinda urwego rushobora kuba rwujuje ubuziranenge bwisi.
Imashini ntarengwa yo guhinduranya irashobora kugabanywa muburyo butaziguye, kuzunguruka, micro-icyerekezo hamwe nubwoko bukomatanyije ukurikije ibikorwa bitandukanye. Imashini ya valve igabanya ubusanzwe ikoresha micro-moteri ihinduranya hamwe na pasiporo itajegajega, kandi impapuro zabo zahinduwe zirimo pole imwe-ebyiri (SPDT), pole imwe-imwe (SPST), nibindi.
Guhindura imipaka yegeranye, bizwi kandi nkurugendo rudafite aho ruhurira, magnetiki induction valve ntarengwa ikoreshwa mubisanzwe ikoresha electromagnetic induction yegereyegere hamwe na pasiporo. Ifishi yo guhinduranya irimo pole imwe-ebyiri-guta (SPDT), inkingi imwe-imwe (SPST), nibindi.
