Nelson Valve Not Turning On

I have two Nelson valves that will not turn on. I have tested the wires and it is receiving a signal. I can't seem to find where the bleed screw is located or how to manually turn on the valves?

The controller is a Nelson SmartZone E-Z.

Thank you.

No bleed screw - manually operate them with a partial turn of the solenoid in a counter-clockwise direction.

I have successfully replaced Nelson solenoids with Irritrol solenoids.
