Part of GRACO's pressure relief valve family with various pressure ratings. Manual reference 308547. Wetted parts are 304 SST and tungsten carbide. This relief valve is part of a selection table for determining appropriate relief valve based on maximum pump fluid pressure. Working pressure range is 950-1150 psi (6.6-7.9 MPa) and cracking pressure range is 1425-1725 psi (9.8-11.9 MPa). Part of relief valve family with different pressure ratings. Selection should be based on maximum pump fluid pressure with lowest pressure relief valve that exceeds system requirements.
