The PAI LPR-5546 is a Benchmark pressure protection valve identified by OEM reference 286500. Pressure protection valves are heavy duty diesel truck parts that regulate air-system supply by closing when pressure reaches a specified threshold, protecting downstream circuits from loss of reservoir pressure. This valve is described with an 85 psig closing pressure and 1/4-18 NPT supply and delivery ports, details that distinguish its configuration for air-system service. Mack cross-references include 745-286500 and 745-286903.
