The GRACO 563163 is an automatic relief indicator designed for use with MSP, MXP, MHH, and MJ divider valves. It is typically constructed from carbon steel or 303 stainless steel and is intended to detect and indicate lube line blockages while allowing the lubrication system to continue operating. This helps maintain system reliability and prevents damage from overpressure.

Key Features:

• Automatic Relief Indicator
• 563163 (also referenced as 508-310-075)
• Carbon steel or 303 stainless steel
• 750 psi (52 bar) ± 20%
• MSP, MXP, MHH, and MJ Divider Valves
• Automatically indicates lube line blockages
• Allows system to continue supplying lubricant during blockage
• Spring-loaded piston resets after pressure relief
• Pressure rating stamped on body for easy identification
• Reliable operation in demanding environments

Applications:
Used in automatic lubrication systems to monitor and indicate blockages in lube lines, ensuring continuous lubrication and preventing equipment damage.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Install according to GRACO equipment manual instructions
• Ensure correct thread type (1/8" NPTF for MJ, 1/8" NPSF w/O-ring for MHH, MSP, MXP)
• Check pressure rating compatibility before installation
• Use appropriate tools and follow safety procedures
• Regularly inspect for signs of wear or malfunction
