Part of GRACO's pressure relief valve family with various pressure ratings. Wetted parts are 304 stainless steel and tungsten carbide. Manual reference 308547. Relief valve selection should be based on Maximum Pump Fluid Pressure with lowest pressure relief valve that has maximum working pressure exceeding the Maximum Pump Fluid Pressure Pressure relief valve prevents system overpressurization. Choose the valve model with the suggested working pressure range appropriate for your equipment and application. Cracking pressure is the pressure at which the valve will relieve pressure to the system.
