The GRACO 16D669 is a stainless steel top inlet block assembly designed for use with the PD44 metering valve system. It functions as a critical component for directing and controlling the flow of materials in GRACO’s meter, mix, and dispense equipment, ensuring reliable and precise material delivery.

Key Features:

• Top Inlet Block Assembly
• PD44, Left Hand
• Stainless Steel
• Maximum Outlet Fluid Working Pressure: 2000 psi (metal sleeves), 400 psi (plastic sleeves); Maximum Air Working Pressure: 100 psi
• Designed for use with GRACO PD44 Meter, Mix, and Dispense Valve systems
• CE approved for standard models (custom configurations may not be CE approved unless specified)
• Stainless steel construction for durability and corrosion resistance
• Precision-engineered for reliable material flow control
• Supports a wide range of material viscosities (water thin to paste)
• Supports various drive options (micrometer, LRT, motor driven)
• Designed for easy integration with PD44 valve assemblies

Applications:
Used in industrial applications requiring precise metering, mixing, and dispensing of adhesives, sealants, and other materials. Suitable for automated and manual dispensing systems in manufacturing, assembly, and maintenance environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment. Non-genuine parts may compromise system integrity and void warranties.
• Ensure all connections are clean and free of debris before assembly
• Use appropriate thread sealant (e.g., Loctite #242 blue or equivalent) on threaded connections
• Torque fasteners to manufacturer specifications (e.g., 67–70 in-lb for piston rod connections)
• Verify compatibility with your specific PD44 configuration before installation
• Follow all safety and operational guidelines provided in the GRACO manual
