The GRACO 25R488 is a mechanical back pressure regulator designed to minimize shear and prevent paint degradation, ensuring consistent finish quality in industrial coating applications. It is constructed from stainless steel (SST) and features a sanitary inlet/outlet for compatibility with demanding environments. Its primary function is to maintain constant back pressure in fluid delivery systems, particularly in paint and coating equipment.

Key Features:

• Back Pressure Regulator
• 25R488, 1.5 in inlet/outlet (38 mm)
• Stainless Steel (SST), ceramic coated seat and flow directors
• 10 gpm (38 lpm) max
• Max working pressure: 300 psi (21.1 bar); Regulated pressure range: 25–250 psi (1.8–17.6 bar)
• Waterborne and solventborne materials
• Low shear flow path geometry for minimal paint degradation
• Ultralife series ceramic coated parts for increased wear resistance and service life
• Sanitary flange inlet/outlet for easy cleaning and maintenance
• Compact, low profile design for easy installation and replacement
• Mechanical operation for reliability and durability

Applications:
Used in industrial paint and coating systems where consistent finish quality and minimal shear are required. Suitable for both waterborne and solventborne materials.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of equipment.
• Ensure proper alignment of sanitary flanges for leak-free operation
• Check compatibility with system pressure and flow requirements before installation
• Regularly inspect and maintain ceramic coated components for wear
• Follow manufacturer guidelines for cleaning and maintenance to prevent contamination and ensure consistent performance
• Use only compatible fluids as specified by GRACO
• Monitor pressure and flow rates during operation to maintain system integrity
• Schedule preventative maintenance to extend service life and minimize downtime
