The GRACO U60339 is a spool/sleeve valve assembly designed for the PD44 Meter, Mix, and Dispense Valve system. It is typically constructed from high-strength materials such as nitrided tool steel for the spool and sleeve, ensuring durability and resistance to wear. This assembly is intended to control the precise metering, mixing, and dispensing of two-component materials (such as epoxies, urethanes, and silicones) in automated industrial applications.

Key Features:

• Spool/Sleeve Valve Assembly
• PD44, RH (Right Hand)
• Nitrided tool steel spool and sleeve (standard); stainless steel metering rods (for other components)
• Up to 1200 psi (82.7 bar) material feed pressure; up to 2000 psi (138 bar) max outlet fluid working pressure for some models
• Compatible with GRACO PD44 Meter, Mix, and Dispense Valve systems
• CE approved for standard models; custom assemblies may not be CE approved unless specified
• Precise metering and mixing of two-component materials
• Improved seal life with matched metering rods and machined seals
• No material hoses between rod pump outlets and mixer inlet, eliminating ratio or shot size problems due to hose expansion/contraction
• Balanced inlet/outlet spool assemblies for reliable operation
• Designed for easy maintenance and cleaning
• High reliability and repeatability for industrial automation

Applications:
Automotive electronics, consumer electronics, medical devices, sporting goods, automotive components (e.g., lighting), appliances, product assembly, potting, gasketing, sealing, encapsulation, syringe filling

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems, reducing downtime and maintenance costs.
• Follow the manufacturer’s installation and maintenance procedures as outlined in the GRACO PD44 Metering Valves and Feed Systems Operation and Maintenance manual.
• Ensure all connections are secure and free from leaks before operation.
• Regularly inspect and maintain seals and spool/sleeve components to prevent material buildup and ensure consistent performance.
• Use only compatible materials and fluids as specified by GRACO.
• Perform routine maintenance checks as recommended by GRACO.
• Replace worn or damaged components promptly to avoid system failure.
• Keep detailed records of maintenance and part replacements.
