Description
Hadley next-generation height control valve (H01501UD) with integral normally-open dump function for Mack, Volvo, and International cab air-suspension systems. The valve modulates air to and from the cab air bags as the chassis articulates, holding ride height and dumping cab pressure on command. Replaces International 2607243C91/2607243C92, Volvo 85124912, and Mack 4069-H01501MS.
