There are two ways to bleed a zone valve for manual operation:

FAQs, Troubleshooting, Video
1- Simply turn the Solenoid

One way is to simply turn the solenoid (the black cylinder with 2 wires) counter-clockwise a 1/4 to 1/2 turn. To shut off the valve, twist the solenoid clockwise until it is snug on the valve.

2- The Bleed Screw

The other way is to use the bleed screw the same way, loosen the screw enough to realease air (1/4 to 1/2 turn). Hand tighten the screw to shut the valve off.
