The GRACO 563051 is a single ball check valve designed for use in high-pressure lubrication and fluid handling systems. Constructed from steel, it ensures reliable one-way flow control and is intended for integration into GRACO equipment to prevent backflow and maintain system integrity.

Key Features:

• Single Ball Check Valve
• 1/8 inch NPTF (M) x 1/8 inch NPSF (F)
• Steel
• Maximum working pressure: 5,000 psi (345 bar); Nominal cracking pressure: 360 psi
• Compatible with GRACO lubrication and fluid handling systems; suitable for use with compatible fluids as specified by GRACO
• Single ball design for reliable one-way flow
• High-pressure tolerance for demanding applications
• Robust steel construction for durability
• Ease of maintenance and replacement

Applications:
Used in industrial lubrication systems, hydraulic circuits, and other high-pressure fluid handling applications where backflow prevention is critical. Suitable for mining, agriculture, and manufacturing environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and safety in high-pressure systems.
• Ensure threads are clean and undamaged before installation
• Apply appropriate thread sealant as recommended by GRACO
• Tighten to recommended torque specifications to prevent leaks
• Inspect regularly for wear or damage and replace as needed
• Regularly check for leaks and proper function
• Replace seals or O-rings as part of routine maintenance
