    i am trying to set the flow control on a set of these valve but am having no success. Directions say to have the flow control turned off, turn the bled screw counterclockwise to turn the water on, adjust the flow control and then tighten (clockwise) the bleed screw to turn the water off. The flow does nothing when the bleed screw has the water on and tightening it does not shut the water off. The timer will turn the station on and off. Does the value have a problem?

    Yep. It has a problem. You will find the cause of the problem stamped right on top of the valve. Look for the words "Lawn Genie" and that is the source of your issue.

    Whenever I adjust a flow control I start wide open on the flow control with the zone running either from the clock or valve and then adjust the flow control down until you see the sprinklers start to decrease.

    I don't even know what a LG 1034 is. (okay, I googled it) I do know you don't use the bleed screw to operate a valve you are fine-tuning.

    Then turn the flow control open 1 1/2 turns.

    Then close the flow control 87 degrees, followed by opening it 91 degrees, and closing it 4 degrees.

    I find it handy to make a laminated pocket chart for my guys with these exact instructions on it. Gotta keep those flow controls set EXACTLY right. :dancing:

    I have never used the flow control to regulate. Variations in water pressure greatly effects the operation. Even air temp, water temp, barometric pressure can change how they operate. It's like using the screw on spray nozzles to control distance, one day they spray 10' the next day they may not spray at all.
