The GRACO 563199 is a single ball check valve constructed from steel, designed to allow fluid flow in one direction while preventing backflow. It is intended for use in high-pressure lubrication and fluid handling systems within GRACO equipment, ensuring reliable operation and system integrity.

Key Features:

• Check Valve
• 1/8 in NPSF (F) x 1/8 in NPTF (M)
• Steel body and ball
• Maximum working pressure: 5,000 psi (345 bar); Nominal cracking pressure: 15 psi (1 bar)
• Designed for use with GRACO lubrication and fluid handling systems
• Single ball design for reliable one-way flow
• High-pressure tolerance for demanding applications
• Compact and robust construction for durability
• Easy to maintain and replace

Applications:
Used in lubrication systems, hydraulic circuits, and other fluid handling applications where prevention of backflow and high-pressure operation are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the system.
• Ensure threads are clean and free from debris before installation
• Apply appropriate thread sealant if required
• Tighten securely to prevent leaks, but avoid over-tightening to prevent damage
• Check for proper flow direction during installation
• Regularly inspect for signs of wear or leakage
• Replace the valve if cracking pressure is not maintained or if backflow is detected
• Follow manufacturer’s recommended maintenance schedule
