The GRACO 557738 is a modular divider valve assembly designed for use in automatic lubrication systems. It is constructed from corrosion-protected steel (with optional stainless steel available) and is intended to precisely distribute lubricant (oil or grease up to NLGI #2) to multiple points in heavy-duty equipment. The assembly requires three tie rods and tie rod nuts for installation.

Key Features:

• Divider Valve
• 9 Section Tie Rod
• Corrosion-protected steel (stainless steel optional)
• Up to 3,500 psi (241 bar)
• For use with Trabon® MSP Divider Valves; compatible with oil or grease up to NLGI #2
• Modular, stackable design for flexibility and easy installation
• Fluoroelastomer o-ring sealing for leak prevention and reduced maintenance
• Built-in check valves to prevent lube re-entry and keep lines full
• Individual valve outputs vary by a maximum ratio of 16:1
• Field-installable crossport or singling plates for increased flow or odd-numbered lube points
• Bypass section available for future expansion or to eliminate a piston section

Applications:
On-road vehicles, off-road equipment, and other heavy-duty machinery requiring precise, multi-point lubrication

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and longevity of the lubrication system.
• Assemble with three tie rods and tie rod nuts as specified
• Ensure all sections are properly aligned and torqued to recommended specifications
• Use field-installable crossport or singling plates if needed for specific flow requirements
• When using bypass sections, ensure a minimum of 3 working sections are present in addition to any bypass sections
• Regularly inspect o-rings and seals for wear and replace as needed to prevent leaks
