The GRACO 501867 Check Valve is a precision-engineered component designed to prevent backflow in fluid delivery systems. It is constructed from stainless steel and PTFE materials, making it compatible with a wide range of finishing materials, including catalysts and waterborne solutions. This valve is intended for use within GRACO equipment to ensure reliable, contamination-free fluid transfer.

Key Features:

• Check Valve
• Stainless steel body with PTFE components
• Maximum working pressure: 3000 psi (207 bar, 20700 kPa, 20.7 MPa)
• Catalyst, waterborne, and other finishing materials
• Prevents fluid backflow to maintain system integrity
• Durable stainless steel and PTFE construction for chemical resistance
• Compact design for easy integration into existing systems
• Reliable performance in high-pressure environments

Applications:
Used in fluid delivery systems for coatings, adhesives, and other finishing materials where backflow prevention is critical. Suitable for industrial, automotive, and manufacturing environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO equipment.
• Ensure the system is depressurized before installation
• Use appropriate thread sealant for NPT connections
• Inspect O-rings and seals for wear before installation
• Follow manufacturer torque specifications for secure fitting
• Regularly inspect for leaks or signs of wear
• Replace O-rings and seals as needed
• Clean valve components to prevent buildup of contaminants
