The GRACO 16A570 is a stainless steel, lightweight top inlet block assembly designed for use with the PD44 Metering Valve system. It serves as a critical component for connecting and directing fluid flow within GRACO’s precision metering, mixing, and dispensing equipment, particularly for two-component materials such as epoxies, urethanes, and silicones.

Key Features:

• Top Inlet Block Assembly
• PD44, 1/4 NPT inlet (as referenced in related documentation)
• Stainless Steel, Lightweight
• Compatible with GRACO PD44 Metering Valve systems
• Stainless steel construction for durability and corrosion resistance
• Lightweight design for ease of handling and installation
• Engineered for reliable performance in precision metering, mixing, and dispensing applications
• Designed for use with reactive resin systems and a wide range of viscosities

Applications:
Used in precision dispensing of two-component materials such as epoxies, urethanes, silicones, and other reactive resin systems. Suitable for applications requiring accurate, repeatable shot sizes from 0.005 cc to 5 cc.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the PD44 metering system.
• Ensure all connections are clean and free of debris before installation
• Follow torque specifications for fasteners as outlined in the PD44 manual (e.g., torque fasteners to 67-70 in-lb for certain components)
• Use appropriate tools and safety equipment during installation
• Refer to the PD44 manual for detailed assembly and maintenance procedures
• Regularly inspect for leaks or wear
• Clean components as recommended by GRACO
• Replace worn or damaged parts with genuine GRACO components
