Near Intersection of I-35 & I-90 Southern Mn. | Yes, that is the control valve I would recommend. The 2123 is the suggested valve cal when used with a Raven 440 type controller. It will be fine with EZ-Boom since EZ-Boom was designed as a drop in replacement for a Raven 440 style controller. The 4 digits affect how the control circuit behaves in the 440. These numbers affect how close is good enough, how fast to move the butterfly etc. The number 2123 is a good starting point but can be changed to alter the response if necessary.
This control valve has the limit switches that I refer to. If you would connect the 2 pin connector to a 12V battery, you should hear the motor run and the butterfly would move slowly open or closed unless it happens to be at the extreme end of its travel. Reversing the wires should cause the butterfly to turn in the opposite direction. It should go from completely closed (straight across) to about 90% open and then stop. The reason the butterfly is not allowed to go that last 10% is that it wouldn't change the flow much and then if it needed to go the opposite direction, it would take quite a while until the butterfly had much effect.
It should take 8 seconds for the valve to go from one extreme to the other.
This control valve can be plumbed inline and act as a throttling valve to alter the flow that gets through the flow meter and eventually to the ground.
This control valve can also be plumbed on a branch of tee ahead of the flow meter. The flow that exits the tee and goes through the control valve is plumbed back to the tank. This is called bypass control. To get more flow to the ground, the control valve would be closed somewhat forcing more of the flow to the ground. The wires leading to the control valve would need to be reversed compared to the other arrangement. This is likely the way your sprayer is plumbed now.
This plumbing arrangement is necessary if your pump is a positive displacement type where the flow must go somewhere. If you are using a centrifugal pump, the inline plumbing arrangement is commonly used since it requires less parts and restricting the pump doesn't cause damage if there is some product flow for cooling.
Remember when plumbing a system such as this that all the flow that passes through the flow meter must get to the ground. If there are any return paths back to the tank after the flow meter, its indications will not be correct.
