The GRACO 563209 is a single ball check valve constructed from steel, designed to allow flow in one direction and prevent backflow in hydraulic or lubrication systems. It is intended for use in high-pressure environments within GRACO equipment, ensuring reliable operation and system integrity.

Key Features:

• Check Valve
• 1/4 in NPSF (F) x 1/4 in NPTF (M)
• Steel
• Maximum working pressure: 5,000 psi (345 bar); Nominal cracking pressure: 250 psi
• Compatible with oil and grease (based on similar GRACO check valve specifications)
• Single ball design for reliable sealing
• High-pressure steel construction for durability
• Designed for use in hydraulic or lubrication systems

Applications:
Used in hydraulic and lubrication systems requiring high-pressure check valves to prevent backflow and maintain system pressure, suitable for industrial, mining, and agricultural equipment.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO equipment.
• Ensure threads are clean and undamaged before installation
• Use appropriate thread sealant for NPTF/NPSF connections
• Tighten to recommended torque specifications
• Inspect for leaks after installation
• Regularly inspect for wear or damage
• Replace if cracking pressure or sealing performance degrades
• Follow manufacturer’s maintenance schedule
