The GRACO 563211 is a single ball check valve constructed from steel, designed to allow fluid flow in one direction while preventing backflow. It is intended for use within GRACO pumping and fluid handling equipment to ensure reliable, leak-free operation under high pressure.

Key Features:

• Single Ball Check Valve
• 1/4 in NPSF (F) x 1/4 in NPTF (M)
• Steel
• Maximum working pressure: 5,000 psi (34.5 MPa, 345 bar)
• Designed for use with GRACO pumps and compatible fluid handling systems
• Single ball design for reliable sealing
• High-pressure capability for demanding applications
• Robust steel construction for durability
• Easy to maintain and replace

Applications:
Used in industrial fluid handling systems, lubrication equipment, and high-pressure pumping applications where reliable check valve performance is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Ensure threads are clean and undamaged before installation
• Use appropriate thread sealant or tape as recommended for the application
• Tighten securely but avoid over-torquing to prevent damage
• Inspect valve and seals regularly for wear or damage
