The GRACO 255977 is a recirculation valve assembly designed for use in GRACO PR70 two-component liquid dispensing systems. It is constructed from stainless steel (SST) and is intended to facilitate the recirculation of materials within the system, ensuring consistent flow and preventing material settling or degradation.

Key Features:

• Recirculation Valve Assembly
• PR70, 1/8NPT
• Stainless Steel (SST)
• GRACO PR70 and PR70v two-component liquid dispensing systems
• Stainless steel construction for durability and corrosion resistance
• Designed for recirculation to maintain material consistency
• Reliable performance in high-pressure, two-component applications

Applications:
Used in GRACO PR70 and PR70v systems for accurate metering, mixing, and dispensing of two-component materials such as adhesives, sealants, and coatings in industrial environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the dispensing system.
• Ensure the system is depressurized before installation
• Use appropriate tools and follow GRACO installation guidelines
• Inspect O-rings and seals for wear before assembly
• Tighten fittings to recommended torque specifications
• Regularly inspect for leaks or wear
• Replace worn or damaged components promptly
• Follow manufacturer-recommended maintenance schedules
