I think its value goes to helping to make others feel comfortable that someone who is more than willing to subject themselves to questioning at any time, an interrogation, and a polygraph, and if they do all that and pass the polygraph, they are considered someone who isn't trying to hide anything.
Most people (and not just LE) upon hearing someone took and passed a polygraph test tend to take the person off their list of possible suspects. Of course nothing in life is 100% except death & taxes, but we're talking about why someone would be considered a suspect versus what would help eliminate them as a suspect. It does make an impression on people.
While polygraphs may not be admissible in court, there's no denying they have some value and provide some information. A passed polygraph often means innocence in the eyes of the public (rightly or wrongly).
