The PAI LRV-3589 is an R-14H relay valve with one 1/2in-14 supply port, two 1/2in-14 delivery ports, one 1/4in-18 control port, and one 1/8in-27 balance port. Relay valves are heavy duty diesel truck parts that use a control-air signal to regulate delivery air within a pneumatic system, and the stated 4 psig cracking pressure and aluminum construction provide useful specifications for matching this configuration. MACK lists 20QE401R as the OEM reference; related MACK references include 20QE419R and 20QE460.
