The GRACO 563182 Rupture-to-Atmosphere Indicator is a safety device designed for use with MX Divider Valves in automatic lubrication systems. It is typically constructed from corrosion-protected steel (with optional stainless steel available for certain models). Its primary function is to protect the lubrication system by venting lubricant to the atmosphere when system pressure exceeds a predetermined threshold (1750 psi in this case), thereby preventing damage to the system and providing a visual indication of excessive pressure.

Key Features:

• Rupture-to-Atmosphere Indicator
• For MX Divider Valves, 1/4 inch-18 inch NPT(f)
• Corrosion-protected steel (optional: Type 316 Stainless Steel)
• 1750 psi
• MX Divider Valves, automatic lubrication systems
• Provides visual indication of excessive system pressure
• Vents lubricant to atmosphere to relieve pressure
• Requires replacement of rupture disc to restart system
• Easy identification of blocked lines or high system pressure
• Reliable and easy to maintain

Applications:
Used in automatic lubrication systems to protect MX Divider Valves and critical bearings from damage due to excessive pressure. Commonly applied in industrial, mining, and agricultural equipment where reliable lubrication is essential.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Install according to GRACO’s recommended procedures for MX Divider Valves
• Ensure proper torque (if specified, e.g., 5 ft-lbs for similar indicators)
• Replace rupture disc after activation
• Regularly inspect for signs of pressure spikes or blockages
• Replace rupture disc after each activation
• Regularly check for leaks or damage
• Follow GRACO’s maintenance schedule for lubrication systems
