The GRACO 116306 is a safety valve designed to regulate and limit air pressure to a maximum of 50 psi (3.4 bar) within GRACO air-operated diaphragm pump (AODD) systems, particularly those used for Diesel Exhaust Fluid (DEF) dispensing. It is typically constructed from robust materials suitable for industrial environments and is intended to ensure safe operation by preventing over-pressurization of the system.

Key Features:

• Safety Valve
• 116306
• 50 psi (3.4 bar)
• GRACO Standard AODD Pump Packages for DEF (e.g., 24V678)
• Prevents system over-pressurization
• Compact and lightweight (approx. 0.11 lbs)
• Reliable operation in industrial settings
• Easy to integrate into existing GRACO DEF dispensing systems

Applications:
Used in GRACO DEF dispensing systems for automotive, heavy-duty dealerships, mining, service and fast lube centers, and fleet maintenance. Ensures safe operation of air-operated diaphragm pumps by limiting air pressure to 50 psi.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and maintains system safety and warranty.
• Install the safety valve in-line with the air supply to the pump as specified in the GRACO equipment manual.
• Ensure all connections are secure and leak-free.
