The GRACO 563156 Automatic Relief Indicator is a performance monitoring device designed for use with MX divider valves in lubrication systems. It is constructed from robust materials (typically carbon steel or stainless steel, depending on variant) and is intended to detect and indicate lube line blockages while allowing the lubrication system to continue supplying other points. This helps maintain machine uptime and protects critical components from lubrication failure.

Key Features:

• Automatic Relief Indicator
• For MX Divider Valves, 1/4" NPT
• Carbon steel or stainless steel (depending on variant)
• 750 psi (52 bar)
• MX Divider Valves
• Pinpoints lube line blockages
• Allows lubrication system to continue supplying other points
• Reliable operation under high pressure
• Easy to identify pressure rating (stamped on body)
• Spring resets piston after pressure relief

Applications:
Used in industrial lubrication systems to monitor and indicate blocked lubrication lines, ensuring continuous lubrication to critical machine points and preventing equipment damage due to lubrication failure.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure correct pressure rating and thread size (1/4" NPT for MX Divider Valves)
• Install in accordance with GRACO equipment manual
• Use a separate pressure switch connected to an audible or visual alarm to warn of high pressure
• If replacing an indicator with a pressure rating no longer available, select the next higher available rating
• Regularly inspect for signs of wear or damage
• Monitor for proper reset of the indicator after pressure relief
• Replace as needed to maintain system integrity
