HydroAir / Balboa Water Group Air control valve with 1/2" inlet. This air control valve draws air from the top of the valve when the handle is turned counterclockwise. The air is then drawn to your jet body via a pipe or manifold system. The air then gets mixed with the water to create a more powerful hydrotherpy massage.
