The GRACO 564336 Terminal Check Valve is a critical component designed for use in the HP-50 High Pressure Lubricator system. It is constructed from hardened and ground alloy steel, featuring a poppet-type valve with a flat face for reliable sealing. This valve is intended to control the flow of lubricant at the terminal point of the lubrication system, ensuring one-way flow and preventing backflow in high-pressure environments.

Key Features:

• Terminal Check Valve
• HP-50, 3/8 in O.D. Tube
• Hardened and ground alloy steel (valve and seat), poppet-type, flat face
• Up to 50,000 psi (344 MPa, 3,447 bar) as part of HP-50 system
• HP-50 High Pressure Lubricator, 3/8 in O.D. tube systems
• Poppet-type valve for reliable sealing
• Hardened and ground alloy steel construction for durability
• Designed for high-pressure lubrication systems
• Ease of maintenance and replacement
• Reliable performance in demanding industrial environments

Applications:
Used in high-pressure lubrication systems for industrial machinery, including mining, manufacturing, and heavy equipment applications. Ensures controlled, one-way flow of lubricant at the terminal point of the system.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system. Non-genuine parts may compromise system integrity and safety.
• Ensure the system is depressurized before installation or maintenance
• Inspect the valve and seat for wear or damage before installation
• Follow the manufacturer’s torque specifications for gland nuts and collars
• Use appropriate tools and safety equipment when working with high-pressure systems
• Regularly inspect and maintain check valves to prevent leaks and ensure proper function
