The GRACO 237074 is a pressure relief valve designed to prevent system over-pressurization in GRACO proportioners, pumps, and spray systems. It is constructed with robust materials suitable for industrial environments and is intended for professional use only.

Key Features:

• Pressure relief valve
• 237074
• Max working pressure: 34.5 MPa (5000 psi)
• For use with select GRACO proportioners, pumps, and spray systems
• Prevents system over-pressurization
• Designed for professional use
• Reliable operation in demanding environments
• Ease of maintenance (replaceable seals if leakage is observed)

Applications:
Used in industrial fluid handling systems, including lubrication, paint, and spray applications, to protect equipment from excessive pressure.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety in high-pressure systems.
• Read all warnings and instructions in the manual before installation
• Apply lubricant to seals and torque connections as specified (e.g., inlet/outlet: 50–60 ft-lb, relief port: 13–15 ft-lb)
• Replace seals if leakage is observed
• Use appropriate tools (e.g., 9/16 in. drag-link socket)
