teoretic poate fi ok piesa ! practic insa ar fi fost infinit mai desteapta daca era proiectata mai inteligent adica exact invers... Mai concret, pe NORMAL INCHIS, adica la disparitia , caderea, avaria, economisirii alimentarii etc valva sa se inchida automat. Asta intrucat in general fluxul de apa implica un consum, utilizarea apei este in cele mai multe cazuri pe intervale mai scurte decat starea de nefolosire (deschizi robinetul sa te speli, sa cureti ceva, sa irigi dupa un anume program ca doar nu inunzi iar apa trebuie la randul ei si contorizata dar si pompata deci alte consumuri si energii). Nu mai punem situatiile oricand incidente posibile de cadere alimentari, epuizare baterii de control si monitorizare etc si atunci ce faci, lasi vana deschisa??? In concluzie astept si versiunea cealalta...
Buna ziua, exista si varianta N/C, Normal Inchisa, disponibila. Nu este o greseala de proiectare, asa a fost facuta pentru cazurile unde este nevoie de acest tip de functionare, de tip N/O.
