The GRACO 116643 is a safety relief valve designed for air systems, typically constructed from durable materials suitable for industrial environments. Its primary function is to automatically relieve excess air pressure in GRACO spray equipment, ensuring safe operation and protecting system components from overpressure damage.

Key Features:

• Safety Relief Valve
• 116643
• 90 PSI (as referenced in some listings; may vary by application)
• Designed for use with GRACO spray equipment, particularly in systems requiring a 90:1 pump package
• Automatic pressure relief
• Compact design (approx. 1.75 in length, 0.7 in height and width)
• Reliable operation for industrial spray applications
• Easily accessible for maintenance

Applications:
Used in GRACO spray foam and spray application systems to prevent overpressure and ensure safe operation of air-driven equipment.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety in your spray equipment system.
• Install the safety relief valve in a location that is easily accessible from the pump and downstream from the air regulator.
• Ensure the valve is properly integrated into the air system to relieve trapped air and prevent overpressure.
• Regularly inspect and maintain the valve to ensure reliable operation.
