The GRACO 563058 is a double ball check valve designed to allow fluid flow in one direction while preventing backflow. It features a brass body and ball construction, making it suitable for use in high-pressure fluid handling systems within GRACO equipment.

Key Features:

• Double Ball Check Valve
• 1/4 in IP (F) x 1/4 in IP (M)
• Brass body and ball
• Maximum working pressure: 3000 psi (207 bar); Nominal cracking pressure: 20-60 psi
• Designed for use with GRACO fluid handling systems and compatible with standard 1/4 in NPT fittings
• Double ball design for reliable sealing and reduced leakage
• Brass construction for durability and corrosion resistance
• Suitable for high-pressure applications

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

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape for NPT connections
• Install in the correct flow direction as indicated on the valve body
• Tighten securely but avoid over-torquing to prevent damage
• Inspect regularly for signs of wear or leakage
• Replace if cracking pressure or sealing performance degrades
• Clean or replace as part of routine maintenance schedules
