The GRACO 564325 is a soft seat single ball check valve designed for use in high-pressure hydraulic or lubrication systems. It features a stainless steel (SST) body and a Viton ball, ensuring compatibility with oil and grease applications. This valve is engineered to allow flow in one direction while preventing backflow, making it ideal for maintaining system integrity in demanding industrial environments.

Key Features:

• Check Valve
• 1/8 NPTF x 1/4 NPSF
• Stainless Steel (SST) Body, Viton Ball
• Maximum working pressure: 7500 psi
• Oil, Grease
• Soft seat design for improved sealing and reliability
• Single ball check mechanism for efficient flow control
• High-pressure capability for demanding applications
• Durable SST and Viton construction for long service life

Applications:
Used in hydraulic and lubrication systems where reliable one-way flow and high-pressure resistance are required, such as in industrial machinery, mining, and agricultural equipment.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment, reducing the risk of leaks or system failures.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape as recommended for NPTF connections
• Tighten connections to manufacturer specifications to prevent leaks
• Inspect valve and seat for damage before installation
• Regularly check for signs of wear or leakage during routine maintenance
