The GRACO 563169 is an automatic relief indicator designed for use with MSP, MXP, MHH, and MJ divider valves. It is constructed to handle high-pressure lubrication systems and is intended to pinpoint lube line blockages while allowing the system to continue supplying lubrication to non-blocked points. The material is not explicitly specified, but similar indicators are typically made from durable metals such as carbon steel or stainless steel for high-pressure applications.

Key Features:

• Automatic Relief Indicator
• 563169
• 3000 psi (207 bar)
• MSP, MXP, MHH, and MJ Divider Valves
• Pinpoints lube line blockages while allowing continued lubrication to non-blocked points
• Pressure is relieved through a vent; spring resets piston after relief
• Color indication: Purple
• No time or effort required for reset after blockage is cleared
• Allows machine to continue running while non-critical bearings are lubricated

Applications:
Used in high-pressure lubrication systems, primarily with secondary divider valves, to ensure continuous lubrication even when a lube point is blocked. Suitable for industrial environments where uninterrupted lubrication is critical, such as mining, manufacturing, and heavy equipment maintenance.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within the lubrication system.
• Ensure correct thread size (1/8" NPTF) for proper fit
• Install in accordance with GRACO equipment manual instructions
• Use a separate pressure switch connected to an audible or visual alarm to warn of high pressure
• Regularly inspect for proper operation and color indication
• Monitor for color changes or pressure relief events
• Replace indicators as needed to maintain system integrity
• Follow manufacturer guidelines for maintenance intervals
