The GRACO 563276 is an air-lube control valve and nozzle assembly designed for use in centralized lubrication systems. It is constructed to handle oil and grease (NLGI #2), and is intended to precisely control and distribute lubricant over a wide area, specifically with an 8-inch spray diameter.

Key Features:

• Control Valve and Nozzle Assembly
• 563276 (8 in. spray diameter, wide)
• Maximum air pressure: 1100 kPa (150 psi)
• Oil and grease (NLGI #2)
• Conserves air—air required only during spray interval
• Versatile—can be used with any centralized lube system
• Reliable performance in industrial environments

Applications:
Used in centralized lubrication systems for industrial equipment, suitable for applications requiring wide-area lubricant distribution such as conveyor systems, mining equipment, and large machinery.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure system is depressurized before installation
• Follow manufacturer’s guidelines for mounting and connection
• Regularly inspect for leaks and proper operation
• Periodically check for blockages or wear in the nozzle
• Use only compatible lubricants (oil or NLGI #2 grease)
• Replace worn or damaged parts promptly
