The GRACO 562647 is a stainless steel double ball check valve designed to allow fluid flow in one direction while preventing backflow. It is intended for use in high-pressure fluid handling systems, such as lubrication and maintenance equipment, to ensure reliable and leak-free operation.

Key Features:

• Check Valve
• 1/8” NPT(F) x 1/8” NPT(M)
• Stainless steel body and ball
• Maximum working pressure: 8000 psi
• Compatible with oil and grease applications
• Double ball design for enhanced reliability and leak prevention
• High-pressure tolerance for demanding industrial environments
• Stainless steel construction for corrosion resistance and durability

Applications:
Used in high-pressure lubrication, maintenance, and fluid handling systems where reliable one-way flow and backflow prevention are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO equipment.
• Ensure threads are clean and free from debris before installation
• Use appropriate thread sealant or tape for NPT connections
