Funzionamento valvole a 2 vie:

Y1 in tensione apre la valvola.

Y2 in tensione chiude la valvola.

Funzionamento valvola a 3 vie:

Y1 in tensione apre la via A - chiude la via B Y2 in tensione apre la via B - chiude la via A

In assenza di tensione su Y1 e Y2 il servomotore, e quindi la valvola, rimangono nella posizione in cui si trovano.
