Kingston Brass HKB1638DFL is a pressure balancing valve tub and shower unit that is designed to provide a consistent water temperature, even when there are changes in water pressure. This can help to prevent scalding or cold showers, and can also save water by reducing the amount of time spent adjusting the water temperature. The valve is also equipped with a diverter handle that allows you to switch between the tub and showerhead, and a temperature regulator that allows you to set the maximum water temperature.
