The GRACO 563504 is a switch assembly designed for use with the Lube Sentry Valve, constructed primarily from steel. It is intended to provide electrical shutdown capability for machinery in series-type lubrication systems, ensuring safety and equipment protection when oil flow is interrupted.

Key Features:

• Electric Lube Sentry Valve Switch Assembly
• Steel
• Up to 6,000 psi (414 bar) system compatibility
• Designed for use with GRACO Lube Sentry Valves in series-type lubrication systems
• Simple, compact design
• Easily removable for maintenance without disturbing existing lines or shutting down equipment
• Reliable electrical shutdown function
• No check valves to avoid trapping contamination

Applications:
Used in series-type lubrication systems for compressors, pumps, and engines to provide automatic warning and shutdown when oil is not flowing properly to primary dividers.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and maintains system safety and performance.
• Install the switch assembly as part of the Lube Sentry Valve between the lube pump and master divider, downstream from any meters or filters
• Ensure proper electrical connections according to system requirements
• Regularly inspect and maintain the switch assembly to ensure reliable operation
• Follow manufacturer guidelines for installation and maintenance
• Use only compatible lubricants (oil with viscosity 450–2,000 SUS)
• Keep seals and components clean to prevent contamination
