The GRACO 563166 Automatic Relief Indicator is a performance indicator designed to detect lube line blockages while allowing the lubrication system to continue supplying other points. It is typically constructed from robust materials such as carbon steel or stainless steel, and is intended for use with MSP, MXP, MHH, and MJ divider valves in automatic lubrication systems.

Key Features:

• Automatic Relief Indicator
• 563166
• Carbon steel or stainless steel (specific material may vary by application)
• 1500 psi (103 bar)
• MSP, MXP, MHH, and MJ Divider Valves
• Automatically resets after blockage is cleared
• Allows machine to continue running while non-critical bearings are lubricated
• No time or effort required for reset after blockage is cleared
• Easy information on blockage location
• Pressure rating stamped on body for easy identification

Applications:
Used in automatic lubrication systems to monitor and indicate blockages in lube lines, ensuring continued lubrication to unaffected points and minimizing downtime.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure correct pressure rating and compatibility with the divider valve type
• Follow manufacturer’s instructions for installation and maintenance
• Use a separate pressure switch connected to an audible or visual alarm to warn of high pressure, as recommended by GRACO
• Regularly inspect indicators for signs of wear or malfunction
• Replace indicators with the same or next higher pressure rating if original is unavailable
• Consult equipment manual for detailed installation and maintenance procedures
