The GRACO 558933 is a magnetically-operated proximity cycle switch designed for use with MS, MX, and MH series divider valves. It is constructed for robust industrial environments and is intended to provide reliable cycle rate monitoring and control within GRACO lubrication and fluid handling equipment.

Key Features:

• Field Sensitive Magnetic Proximity Cycle Switch
• 3-Pin, for MS, MX, and MH Divider Valves
• Industrial-grade, explosion-proof (where specified)
• Up to 10,000 psi (690 bar) in some configurations; check specific valve compatibility
• MS, MX, and MH series divider valves
• Explosion-proof (where specified)
• Magnetically-operated for reliable sensing
• Cycle rates up to 200 CPM
• Available in 115 VAC or 12-32 VDC versions
• Robust construction for harsh environments
• Easy visual cycle indicator pin

Applications:
Used in industrial lubrication systems, progressive lubrication, and fluid handling applications where precise cycle monitoring and control are required.

Installation Notes:

• Ensures compatibility, reliability, and safety within GRACO equipment.
• For MS and MH valve sections, torque to 6-8 ft/lbs for o-ring seal; 10 ft/lbs for gasket seals.
• Leave cycle indicator pin installed for visual cycle monitoring.
• Ensure proper electrical connections for 115 VAC or 12-32 VDC as required.
