The GRACO 15R145 is a relief valve designed to protect equipment from overpressure by releasing excess pressure at a set point. It is constructed with a male 1/4 NPT connection and is set to relieve at 40 PSI. The material is not explicitly stated, but typical GRACO relief valves are made from durable metals and elastomers suitable for industrial environments. This valve is intended for use within GRACO lubrication and fluid handling systems to ensure safe operation and prevent damage to pumps and downstream components.

Key Features:

• Relief Valve
• 1/4 NPT, Male, 40 PSI, SIL
• 40 PSI (relief setting)
• GRACO lubrication and fluid handling systems
• Compact size for easy integration
• Reliable pressure relief at set point
• Designed for industrial duty cycles

Applications:
Used in GRACO lubrication systems to protect pumps and downstream equipment from overpressure, suitable for industrial and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and maintains warranty coverage.
• Ensure the system is depressurized before installation
• Use appropriate thread sealant for NPT connections
• Verify correct orientation and secure tightening
• Test the valve after installation to confirm proper relief function
• Regularly inspect for leaks or damage
• Replace if relief function is compromised
• Follow GRACO’s recommended maintenance schedule
