The GRACO 964000 Base, PD44, Pneumatic Micrometer is a precision metering valve base unit designed for use with the PD44 series. It is typically constructed from industrial-grade materials suitable for handling a range of low to high viscosity fluids. The part is intended to provide accurate and repeatable dispensing of materials such as adhesives, epoxies, urethanes, and silicones within GRACO dispensing systems.

Key Features:

• Pneumatic micrometer metering valve base
• PD44
• Compatible with PD44 series valves and various feed systems (cartridge, transfer pumps, reservoir tanks)
• Precise mix ratio and shot repeatability
• Improved low viscosity spool design
• Rod positive displacement metering
• Eliminates cleaning and potential hardening of materials in the valve
• Reliable and easy to maintain

Applications:
Accurate dispensing of two-component epoxies, urethanes, silicone, and most reactive resin systems in small amounts (0.005 cc to 5 cc per shot). Suitable for industrial, manufacturing, and maintenance applications requiring precise material application.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems.
• Ensure proper alignment and secure mounting of the base unit
• Connect to a suitable compressed air supply as per system requirements
• Follow manufacturer guidelines for material feed system integration
• Regularly inspect and maintain the valve and base for optimal operation
