The PAI EM56780 is a safety valve adjustable to a 150 psig cracking-pressure setting. Safety valves are heavy duty diesel truck parts that protect pressurized air systems by opening when system pressure reaches the valve’s set threshold, routing excess pressure away from the protected circuit. MACK lists 745-205105 as the OEM reference for this valve.
