The 24F456 is a stainless steel spool valve assembly designed for the GRACO PD44 series, intended for precise metering and dispensing of two-component materials such as epoxies, urethanes, and silicones. It is engineered for high-volume applications and is constructed from stainless steel for durability and chemical resistance.

Key Features:

• Spool Valve Assembly
• PD44, High Volume (HV), Stainless Steel (SS), Type A
• Stainless Steel
• Maximum Outlet Fluid Working Pressure: 2000 psi; Maximum Material Inlet Pressure (Metal Sleeves): 1200 psi
• Designed for use with GRACO PD44 metering and dispensing systems
• Balanced inlet/outlet spool assemblies for precise material control
• Improved low viscosity spool design
• Rod positive displacement metering for accurate shot size and mix ratio
• Eliminates cleaning and potential hardening of materials in the valve
• Reliable, easy to maintain, and suitable for high duty cycles

Applications:
Used for micro-dispensing of two-component reactive materials such as epoxies, urethanes, and silicones in industrial, manufacturing, and assembly applications. Suitable for applications requiring precise mix ratios and repeatable shot sizes from 0.005 cc to 5.0 cc.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the PD44 system.
• Ensure all components are clean and free of debris before installation
• Lubricate metering rod ports and spool valve ports with compatible lubricant such as mesamoll or silicone oil
• Follow manufacturer guidelines for assembly and torque specifications
• Regularly inspect and maintain seals and O-rings for optimal performance
• Use only compatible lubricants and replacement parts
• Monitor system for leaks and wear
• Refer to the GRACO PD44 manual for detailed installation and maintenance procedures
