The GRACO 916154 is a manual back pressure regulator designed for low-pressure, corrosion-resistant applications. Constructed from stainless steel and carbide, it is intended to control upstream fluid pressure in fluid circulation systems, particularly for use with catalysts and waterborne materials in industrial finishing processes.

Key Features:

• Back Pressure Regulator
• 1-1/4 in (31.75 mm) inlet/outlet
• Stainless Steel, Celcon Diaphragm, Nylon Fabric Base with Impregnated Buna-N, PTFE
• 15 GPM
• Maximum Regulated Pressure: 200 psi (14 bar); Minimum Regulated Pressure: 5 psi (0.3 bar); Maximum Working Pressure: 300 psi
• Catalyst, Waterborne materials
• Low-pressure, corrosion-resistant design
• Manual operation
• Includes gauge for pressure monitoring
• Reduces paint shear for consistent finish quality
• Reliable for demanding industrial environments

Applications:
Used in industrial fluid circulation systems to maintain consistent upstream pressure, especially in paint and coating applications where low shear and corrosion resistance are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO equipment.
• Ensure proper thread engagement (NPT) for both inlet and outlet connections
• Install gauge in the provided 1/4 in NPT gauge port for pressure monitoring
• Follow manufacturer guidelines for maximum and minimum pressure settings
• Regularly inspect for leaks and wear, especially in corrosive environments
