The GRACO 237112 VALVE, RELIEF is a pressure relief valve designed to prevent system over-pressurization in select GRACO proportioners, pumps, and spray systems. It is intended for professional use and helps protect equipment and operators by safely venting excess pressure. While specific material details for the 237112 are not listed in available documentation, similar GRACO relief valves are constructed with wetted parts made from 304 stainless steel, graphite-filled PTFE, UHMWPE, and tungsten carbide (nickel binder) for durability and chemical resistance.

Key Features:

• Pressure relief valve
• 237112 VALVE, RELIEF
• Maximum working pressure: 2250 psi (155 bar, 15.5 MPa) (based on similar model reference in GRACO documentation; confirm for exact model)
• For use with select GRACO proportioners, pumps, and spray systems
• Spring-loaded needle design for reliable pressure relief
• Designed for ease of maintenance (replaceable seals if leakage observed)
• Robust construction for professional and industrial environments
• Low noise level (<70 dBA) for operator comfort

Applications:
Used in industrial and professional fluid handling systems to prevent over-pressurization, ensuring safe operation of GRACO pumps, proportioners, and spray equipment.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety. Non-genuine parts may compromise system integrity and safety.
• Read all warnings and instructions in the manual before installation or maintenance.
• Be familiar with proper control and usage of the equipment.
• Replace seals if leakage is observed.
• Apply appropriate lubricant as specified in the manual.
• Torque fittings to manufacturer-recommended specifications (e.g., 50–60 ft-lb for 1/2 NPT(f) inlet/outlet, 13–15 ft-lb for 1/2 NPT(m) relief port, 75–85 ft-lb for other specified fittings; confirm for exact model).
• Use a 9/16 in. drag-link socket for installation if required.
• Regularly inspect for leaks and replace seals as needed.
• Follow GRACO’s recommended maintenance schedule.
• Keep documentation and manuals for reference.
