A pressure relief valve (110) for a fluid power assist steering system. The valve includes a housing (116) and a spool (120) disposed in the housing. The spool defines a cavity (136) and has a first end (140) and a second end (141). The spool is movable in the housing to limit an output pressure of the pump. A poppet seat (138) is secured to the second end of the spool. A poppet (142) is disposed in the cavity. A poppet spring (144) biases the poppet into engagement with the poppet seat. A set screw (200) is received in the first end of the spool. The set screw is rotatable relative to the spool to adjust a compression level of the poppet spring.
