The GRACO A1000164 is a piston pinch lower component, specifically designed for use in GRACO’s positive displacement pinch action dispense valves. It is typically constructed from durable materials suitable for industrial environments and is intended to ensure reliable operation and volumetric consistency in dispensing applications. This part is critical for the proper functioning of the valve assembly, particularly in systems requiring precise dot-to-dot dispensing of materials ranging from low to high viscosity.

Key Features:

• Piston, Pinch, Lower
• 902-20, 0.090
• Compatible with GRACO 902-20 positive displacement pinch action dispense valves
• Designed for volumetric consistency in dispensing
• Critical for fail-safe operation and preventing material dumping
• All wetted parts are disposable for easy maintenance and cleaning (system feature)
• Micrometer adjustment for precise control (system feature)

Applications:
Used in industrial dispensing systems for precise application of adhesives, sealants, epoxies, and metal-filled pastes. Suitable for applications requiring dot-to-dot volumetric consistency and reliable operation in automated or manual dispensing environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the dispensing system. Non-genuine parts may compromise system integrity and safety.
• Ensure the system is depressurized before installation or maintenance
• Follow all safety instructions and warnings in the GRACO manual
• Replace all wetted parts as recommended for maintenance and cleaning
• Use appropriate tools and training for installation and maintenance
• Regularly inspect and replace worn or damaged components
• Keep spare parts on hand to minimize downtime
• Train personnel on proper handling and installation procedures
