The GRACO 563061 is a double ball check valve designed to allow fluid flow in one direction while preventing backflow. It features a stainless steel (SST) body and Viton (FKM) balls, making it suitable for use with oil and grease in high-pressure environments. This valve is commonly used in compressor equipment and lubrication systems to ensure reliable, leak-free operation.

Key Features:

• Check Valve
• 1/4 in NPSF (F) x 1/4 in NPSF (F)
• Stainless steel (SST) body, Viton (FKM) balls
• Maximum working pressure: 7500 psi (517 bar); Maximum cracking pressure: 48 psi nominal (50 psi max)
• Oil, grease
• Double ball design for enhanced reliability and leak prevention
• High-pressure capability suitable for demanding industrial applications
• Corrosion-resistant stainless steel construction
• Viton balls for chemical and temperature resistance

Applications:
Used in compressor equipment and lubrication systems where reliable, one-way flow and high-pressure resistance are required. Suitable for industrial environments such as mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO equipment. Non-genuine parts may compromise system integrity and safety.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape compatible with the application
• Tighten to manufacturer-recommended torque specifications
• Verify correct orientation for flow direction
• Inspect for leaks after installation and during routine maintenance
• Regularly inspect for signs of wear, leakage, or damage
• Replace valve if performance deteriorates or if leaks are detected
• Follow GRACO’s recommended maintenance schedule for the specific equipment
