The GRACO 563056 is a single ball check valve designed for high-pressure applications. It features a stainless steel (SST) body and a steel ball, ensuring durability and resistance to harsh environments. This valve is intended to allow fluid flow in one direction while preventing backflow, commonly used in lubrication and hydraulic systems within GRACO equipment.

Key Features:

• Check Valve
• 9/16-18 SAE
• Stainless Steel (SST) Body, Steel Ball
• Maximum Working Pressure: 5000 psi (as per product name; note: similar GRACO check valves may have lower pressure ratings, but this product is specified at 5000 psi)
• Compatible with oil and grease (based on similar GRACO check valve models)
• Single ball design for reliable one-way flow
• High-pressure capability for demanding applications
• Stainless steel construction for corrosion resistance
• Steel ball for durability and long service life

Applications:
Used in high-pressure lubrication and hydraulic systems, including industrial, mining, and agricultural equipment where reliable one-way flow and backflow prevention are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO systems.
• Ensure threads are clean and undamaged before installation
• Use appropriate thread sealant or tape as recommended by GRACO
• Tighten to recommended torque specifications to prevent leaks and ensure proper sealing
• Inspect valve and seals for wear or damage before installation
• Regularly inspect for leaks or signs of wear
• Replace valve if cracking pressure or sealing performance degrades
• Use only compatible fluids as specified by GRACO
