The GRACO 6311-177 is a check valve constructed from EPDM (ethylene propylene diene monomer) rubber, designed for use in GRACO fluid handling equipment. Its primary function is to allow fluid flow in one direction while preventing backflow, ensuring system integrity and safety in various industrial applications.

Key Features:

• Check Valve
• EPDM (ethylene propylene diene monomer) rubber
• Designed for GRACO fluid handling equipment
• Prevents backflow to protect equipment
• Durable EPDM construction for chemical resistance
• Reliable performance in demanding environments

Applications:
Used in industrial fluid handling systems where prevention of backflow is critical, such as in lubrication, chemical transfer, and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of your equipment.
• Ensure the valve is installed in the correct flow direction as indicated on the valve body
• Inspect for any damage or debris before installation
• Follow GRACO equipment manual for specific installation procedures
• Regularly inspect the valve for wear or chemical degradation
• Replace if signs of leakage or reduced performance are observed
• Use only compatible fluids as recommended by GRACO
