The GRACO 24F455 is a spool valve assembly designed for use in the PD44 series of metering and dispensing systems. It is typically constructed from robust materials suitable for industrial environments and is intended to control the flow and metering of materials such as adhesives, sealants, or other fluids in precision dispensing applications.

Key Features:

• Spool Valve Assembly
• PD44, HV (High Viscosity), HS (High Speed), A Side
• Up to 1200 psi (8 MPa, 83 bar) inlet working pressure for PD44 series (specific to valve assembly may vary; consult manual for exact rating)
• Designed for use with GRACO PD44 metering and dispensing systems
• Balanced inlet/outlet spool assemblies for precise material control
• Does not displace material while shifting between reload and dispense positions
• Allows pressure feeding of materials up to 1200 psi during reloading
• Isolates materials from mixer inlet during reload
• Accurate volume metering via rod displacement technology
• Reliable and easy to maintain with accessible lubrication points

Applications:
Precision dispensing of small amounts of water-thin to paste viscosity materials (0.005 cc to 5 cc) in industrial, manufacturing, or assembly processes. Commonly used for two-component adhesives, sealants, or other reactive materials.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment, reducing downtime and maintenance costs.
• Lubricate metering rod ports and spool valve ports with compatible lubricant such as mesamoll or silicone oil before installation
• Ensure all connections are secure and free from contamination
• Follow manufacturer’s guidelines for installation and maintenance
• Regularly inspect and maintain lubrication points for smooth operation
