Irritrol Valve Setting

Having recently moved house I wanted to save the lawn and replace the watering system. I just purchased and installed a manifold holding 6 off 25mm Irritrol Model 2500MTF valves. They all seem to actuate with the controller but the water pressure delivered to the sprinklers seems low and some of the valves seem to allow water passage even when not activated. The valves have a centrol flow control screw, which I have backed off to allow the valves to open fully, but they also have what look like On/Off switches under the solenoid and smaller plastic adjuster screws in the valve topnear the solenoids. I can find nothing to tell me what these things do. Can anyone out there help me?
