Pressure relief valves prevent 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. Part number 24W475 appears as a model designation in the parts list. Related parts for this model include: 237018 (all other models), 24W476 (model 24W475) for the needle valve; 16N786 UHMWPE (model 24W475) for the seal; and 17C238 (model 24W475) for the retainer seal. The manual indicates to keep spare parts on hand to reduce down time. Part 24W475 is referenced as a model in the wetted parts specification alongside tungsten carbide (nickel binder) components. The page shows technical specifications for a spring-loaded needle valve system but does not provide detailed specifications specifically for the 24W475 relief valve.
