The GRACO 563203 is a double ball check valve constructed from stainless steel (SST), designed to allow fluid flow in one direction while preventing backflow. It is intended for use in high-pressure fluid handling systems within GRACO equipment, ensuring reliable operation and system integrity.

Key Features:

• Double Ball Check Valve
• Twin Tandem, 1/4 in NPTF (M) x 1/8 in NPTF (M)
• Stainless Steel (SST)
• Nominal cracking pressure: 45 psi; Maximum working pressure: 10,000 psi
• Compatible with GRACO equipment requiring 1/4 in NPTF (M) inlet and 1/8 in NPTF (M) outlet connections
• Double ball design for enhanced reliability and leak prevention
• High-pressure tolerance for demanding industrial applications
• Twin tandem configuration for robust performance
• Stainless steel construction for durability and corrosion resistance

Applications:
Used in high-pressure fluid transfer systems, lubrication systems, and other industrial applications where reliable check valve performance is critical.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape for NPTF connections
• Tighten connections to recommended torque specifications
• Inspect valve for proper operation after installation
• Regularly inspect for leaks or signs of wear
• Replace valve if performance degrades or leaks are detected
• Follow GRACO maintenance guidelines for system longevity
