The GRACO 187851 STEM VALVE is a precision-engineered component designed for use in GRACO fluid pressure regulators and related equipment. It is a critical internal part that helps control the flow and pressure of fluids within the system. The specific material is not specified in available documentation, but it is typically made from durable metals or alloys to withstand operational stresses. Its intended function is to regulate or shut off fluid flow as part of the valve assembly in GRACO equipment.

Key Features:

• Stem valve
• Compatible with select GRACO fluid pressure regulators and related equipment
• Precision fit for reliable operation
• Designed for easy replacement and maintenance
• Critical for accurate pressure and flow control

Applications:
Used in GRACO fluid pressure regulators and similar equipment for controlling fluid flow and pressure in industrial lubrication, maintenance, and fluid handling systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of equipment. Non-genuine parts may compromise system integrity and void warranties.
• Always refer to the equipment manual for specific installation instructions
• Ensure the system is depressurized before replacing or installing the stem valve
• Inspect the valve seat and surrounding components for wear or damage during installation
• Use appropriate tools and follow torque specifications if provided
• Regularly inspect the stem valve for signs of wear or leakage
• Replace the stem valve as part of routine maintenance or if performance issues arise
• Keep spare parts on hand to minimize downtime
