The GRACO PD44 Meter Mix Dispense Valve is a motor-driven metering and mixing valve designed for precise dispensing of two-component materials. It is typically constructed from robust industrial materials suitable for handling adhesives, sealants, and similar fluids. Its primary function is to accurately meter, mix, and dispense materials in industrial applications, ensuring consistent ratios and reliable performance within GRACO dispensing systems.

Key Features:

• Meter Mix Dispense Valve
• PD44, Motor Driven
• Max Outlet Fluid Working Pressure: 2000 psi (14 MPa, 138 bar); Max Inlet Working Pressure: 1200 psi (8 MPa, 83 bar); Max Air Working Pressure: 100 psi (0.7 MPa, 7 bar)
• Designed for use with GRACO dispensing systems and compatible with a range of two-component materials
• CE approved for standard models (custom models may not be CE approved unless specified)
• Balanced inlet/outlet spool assemblies for material isolation and pressure feeding
• Rod displacement metering technology for precise volume control
• Purge timer, cycle counter, and totalizer for process monitoring
• Motor driven controls with NEMA 23 stepper motor for shot size and flow rate adjustment
• Reliable, easy-to-maintain design for industrial environments

Applications:
Industrial dispensing of two-component adhesives, sealants, and similar materials where accurate metering and mixing are required. Suitable for manufacturing, assembly, and maintenance operations across various industries.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure compressed air supply meets requirements (0.1 to 2.58 CFM at 80 psi)
• Follow manufacturer guidelines for mounting and connecting the valve to the dispensing system
• Regularly inspect and maintain the valve and associated components to prevent leaks and ensure consistent operation
• Monitor cycle counters and totalizers for usage tracking
• Perform routine cleaning and inspection of the valve and mixer
• Replace disposable mixers as recommended
