Description
The GRACO 237073 is a pressure relief valve designed to prevent system over-pressurization in select GRACO proportioners, pumps, and spray systems. It is constructed with wetted parts typically made from 304 stainless steel, graphite-filled PTFE, UHMWPE (model 24W475), and tungsten carbide with a nickel binder. This valve is intended for professional use only and helps maintain safe operating pressures within GRACO equipment.
