The GRACO 563157 is an automatic relief indicator designed for use with MX divider valves. It is constructed to handle oil and grease, and is intended to detect lube line blockages while allowing the lubrication system to continue supplying other points. This helps maintain equipment uptime and reliability.

Key Features:

• Relief Valve / Automatic Relief Indicator
• MX Divider Valves, 1/4 in NPTF thread
• Maximum working pressure: 1000 psi (69 bar, 6900 kPa, 7 MPa)
• Works with MSP, MX, MXP, MJ, and MHH divider valves; compatible with oil and grease
• Automatically resets after blockage is cleared
• Pinpoints blocked lines, high system pressure, or blocked bearings
• No time or effort required for reset after blockage is cleared
• Allows lube system to continue supplying lubrication to non-blocked points

Applications:
In-plant machinery, off-road equipment, compressor equipment, and other industrial lubrication systems where continuous lubrication is critical.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure correct thread type (1/4 in NPTF for MX divider valves)
• Install in accordance with GRACO equipment manual
• Regularly inspect for signs of blockage or pressure issues
• Use a separate pressure switch connected to an audible or visual alarm to warn of high pressure (recommended by GRACO)
