If the valve is equipped with an electric solenoid, the ON/OFF function can be automatic by using an electric controller. When the selector is pointed to the "AUTO" position then the electric solenoid is used to automatically open or close the valve. The 3-way electric solenoid must be energized to open the valve and de-energized to close the valve. Pointing the manual selector handle to "OPEN" or "CLOSE" will override the "AUTO" control.
