The GRACO 560340 is a hardened and ground alloy steel valve seat designed for use in HP50 High Pressure Lubricators. It serves as a critical sealing component within the lubricator’s valve assembly, ensuring reliable operation under high pressure conditions.

Key Features:

• Valve Seat
• HP50 High Pressure Lubricator
• Hardened and ground alloy steel (CRS AISI A2 Med Alloy)
• Up to 50,000 psi (344 MPa, 3,447 bar) for HP50
• HP50 High Pressure Lubricators; also referenced as Lubriquip 463-910-020 and Manzel HP-60-1-6
• Hardened and ground for durability and wear resistance
• Precision-machined for reliable sealing
• Designed for high-pressure environments
• Integral to the reliable operation of the lubricator

Applications:
Used in high-pressure lubrication systems for industrial machinery, mining, and heavy equipment where reliable, high-pressure grease delivery is required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the HP50 High Pressure Lubricator. Non-genuine parts may compromise system integrity and safety.
• Ensure the lubricator is depressurized and isolated before servicing
• Inspect the valve seat and mating surfaces for wear or damage prior to installation
• Follow the manufacturer’s recommended torque specifications for assembly
• Use appropriate tools to avoid damaging the hardened surfaces
• Refer to the equipment manual for detailed installation and maintenance procedures
