I uploaded that PVB photo for a reason, and that is because it will closely match what you should end up with. The DCVA you were told about is "old tech" from the days when a lawn sprinkler system was not considered a possible source of toxic backflow. Since then, your lawn sprinkler system has graduated to "toxic" status, and that new status gets you a PVB for protection, height requirements included.
