The GRACO 563171 is an automatic relief indicator designed for use with MSP, MXP, MHH, and MJ divider valves. It features an O-ring seal and is constructed for reliable performance in lubrication systems. Its primary function is to detect and indicate lube line blockages while allowing the system to continue supplying lubrication to other points, ensuring uninterrupted machine operation.

Key Features:

• Automatic Relief Indicator
• 1/8 in. NPT
• 1000 psi (69 bar)
• MSP, MXP, MHH, and MJ Divider Valves
• Spring-loaded piston unseats when blockage occurs, venting lubricant to atmosphere
• Allows lubrication system to continue operating when a lube point is blocked
• Pressure rating stamped on the body for easy identification
• Reliable performance in demanding environments
• Easy to maintain and replace

Applications:
Used in lubrication systems to monitor and indicate blockages in lube lines, ensuring critical machine points continue to receive lubrication even if one line is blocked. Suitable for industrial, mining, and agricultural equipment.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper thread engagement and torque when installing the indicator
• Check O-ring seal for integrity before installation
• Install in a location where vented lubricant will not cause contamination or safety issues
• Regularly inspect for signs of leakage or malfunction
• Periodically check the indicator for proper operation and signs of wear
• Replace O-ring seals as needed to maintain leak-free performance
• Monitor system pressure and address any persistent high-pressure alarms
