This valve assembly is found on Hot Spot and Limelight spa models from 2008 through 2014. It is used to turn on and off the bar top Amur water feature that runs off one of the jet pumps in the spa. This valve turns 270 degrees, for 2014 Limelight tubs, please verify how far your existing valve turns. If it turns 270 degrees, this is the correct replacement. If your existing valve only turns 90 degrees, the correct replacement is part number 77430.
