The GRACO 563047 is a single ball check valve designed for use in high-pressure lubrication and hydraulic systems. It features a stainless steel (SST) body and a nitrile butadiene rubber (NBR) ball, ensuring durability and resistance to harsh operating conditions. This valve is intended to allow flow in one direction and prevent backflow, making it suitable for integration into GRACO equipment for reliable fluid control.

Key Features:

• Single Ball Check Valve
• 1/4 in NPSF (F) x 1/8 in NPSF (F)
• Stainless steel (SST) body, NBR ball
• 7500 psi maximum working pressure
• Designed for use with GRACO lubrication and hydraulic equipment
• High-pressure capability (up to 7500 psi)
• Robust stainless steel construction for durability
• NBR ball for reliable sealing and chemical resistance
• Compact design for easy integration into systems

Applications:
Used in medium-duty pumps and metering lubrication equipment for applications requiring reliable one-way flow control in hydraulic or lubrication systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment, reducing the risk of leaks or system failures.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape as recommended by GRACO
• Tighten to recommended torque specifications to avoid damage
• Inspect O-rings and seals for wear during installation and maintenance
• Regularly check for leaks and replace worn components as needed
• Keep spare O-rings and seals on hand for quick replacement
• Periodically inspect the valve for signs of wear or damage
• Follow GRACO’s recommended maintenance schedule for lubrication equipment
