The GRACO 563174 is an automatic relief indicator designed for use with MSP, MXP, MHH, and MJ divider valves. It features a 1/8 in. NPT connection with an O-ring seal and is rated for 2000 psi (138 bar). Its primary function is to indicate when excessive pressure is relieved in lubrication systems, helping to prevent equipment damage and maintain system integrity.

Key Features:

• Automatic Relief Indicator
• 1/8 in. NPT
• 2000 psi (138 bar)
• MSP, MXP, MHH, and MJ Divider Valves
• Automatic relief indication for blocked lube points
• O-ring seal for leak prevention
• Allows system to continue operating during blockages
• Pressure rating stamped on body for easy identification
• Reliable spring reset mechanism

Applications:
Used in lubrication systems to monitor and indicate relief of excessive pressure, particularly in industrial and heavy equipment applications where divider valves are employed.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure correct thread size (1/8 in. NPT) and O-ring seal are used for leak-free installation
• Install in accordance with GRACO equipment manual instructions
• Regularly inspect for signs of wear or damage and replace as needed
• If replacing an indicator with a discontinued pressure rating, select the next higher available rating
