The GRACO 557227 is a grease zone valve designed for use in automatic lubrication systems. It is constructed for reliable shut-off and control of grease flow in zoned lubrication applications. The valve features BSPP (British Standard Pipe Parallel) ports, operates at 24 VDC, and is intended for use with up to NLGI #2 grease. Its robust design ensures zero-leak performance and compatibility with demanding industrial environments.

Key Features:

• Grease Zone Valve
• Inline BSPP Ported, 1/4 in. Ports, M12 Male
• For use with up to NLGI #2 grease; compatible with zoned shut-off systems
• Zero-leak valve assembly for reliable shut-off
• 24 VDC operation for integration with automated systems
• BSPP ported for secure, leak-resistant connections
• M12 male connector for easy electrical integration
• Same dimensions as GRACO grease reservoirs for streamlined installation
• Includes oil fill cap for maintenance convenience

Applications:
Used in automatic lubrication systems for industrial machinery, particularly where zoned shut-off and precise grease delivery are required. Suitable for environments demanding reliable, leak-free operation and easy integration with automated controls.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper alignment and secure connection of BSPP ports to prevent leaks
• Verify electrical compatibility with 24 VDC systems before installation
• Use appropriate tools and follow torque specifications for fittings
• Regularly inspect for leaks and proper valve operation as part of routine maintenance
• Consult GRACO documentation for specific installation and maintenance procedures
