The GRACO 563159 is an automatic relief indicator designed for use with MX divider valves. It is typically constructed from robust materials such as carbon steel or stainless steel (specific material not always specified in available documentation). Its primary function is to monitor and indicate high system pressure or blocked lubrication lines, allowing the lubrication system to continue supplying grease to other points while alerting operators to issues at specific locations.

Key Features:

• Automatic Relief Indicator
• 563159 (for MX Divider Valves)
• 2000 psi (138 bar)
• MX Divider Valves
• Automatically resets after blockage is cleared—no manual reset required
• Provides easy visual indication of blocked lines or high system pressure
• Allows lubrication system to continue operating for non-blocked points
• Reliable performance in demanding industrial environments

Applications:
Used in automatic lubrication systems to monitor and indicate blocked lubrication lines or excessive pressure, ensuring continued lubrication to critical machine points while alerting maintenance personnel to issues.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Install according to GRACO equipment manual instructions
• Ensure proper orientation and secure fitting to prevent leaks
• Regularly inspect for signs of wear or damage
• Use only GRACO-supplied replacement parts for maintenance
• Follow manufacturer’s recommended maintenance schedule
• Monitor system pressure and indicator status regularly
• Replace indicators with the same or next higher pressure rating if original is unavailable
