Valves - Manually Opening a Valve

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

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.

Open the Bleed Screw

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