The GRACO 564335 is a discharge check valve designed for use with HP-50 high pressure lubricators. It is constructed with hardened and ground alloy steel components for durability and is intended to control the flow of lubricant within the system, ensuring reliable operation and preventing backflow.

Key Features:

• Discharge check valve
• HP-50, 3/8 in O.D. Tube
• Hardened and ground alloy steel (valve and seat), poppet type, flat face
• HP-50 Maximum Operating Pressure: 50,000 psi (344 MPa, 3,447 bar)
• HP-50 High Pressure Lubricators
• Poppet type, flat face design for reliable sealing
• Hardened and ground alloy steel construction for durability
• Designed for high-pressure lubrication systems
• Ease of maintenance due to robust construction

Applications:
Used in high-pressure lubrication systems, particularly with GRACO HP-50 lubricators, suitable for industrial environments requiring reliable and durable lubrication solutions.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure the system is depressurized before installation
