Wiring diagram

Proportional valve description 008

Black wire is commen wire.

Brown wire is open wire, when power is on, valve will turn counterclock wise, valve open.

Red wire is close wire, when power is on, valve will turn clock wise, valve close.

When power failure, valve will stay at current position. So, the open angle can be fixed according to the time of power supply.
