The GRACO 25P086 is a valve kit designed for use in GRACO diaphragm pumps, specifically as a flapper valve check kit. It is constructed from 316 stainless steel (SST), making it highly resistant to corrosion and suitable for demanding industrial environments. This kit is intended to replace or upgrade the check valve components within compatible GRACO pump models, ensuring reliable fluid control and preventing backflow.

Key Features:

• Flapper Valve Check Kit
• 4-inch
• 316 Stainless Steel (SST)
• Compatible with GRACO SaniForce 4150, 4-inch HS SST Pneumatic Diaphragm Pump and similar models
• Corrosion-resistant 316 SST construction for durability
• Designed for easy replacement and maintenance
• Reliable check valve function to prevent backflow
• Suitable for high sanitation and industrial applications

Applications:
This kit is used in high sanitation and industrial fluid handling applications, particularly in GRACO SaniForce 4150 and similar diaphragm pumps. It is ideal for industries requiring robust, corrosion-resistant valve solutions, such as food and beverage, pharmaceutical, and chemical processing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of the equipment. Non-genuine parts may compromise pump reliability and safety.
• Ensure the pump is depressurized and isolated before installation
• Follow the manufacturer’s instructions for valve orientation and assembly, especially for horizontal pumps where flapper orientation is critical
• Inspect all components for damage before installation
• Use appropriate tools and safety equipment during installation
• Refer to the equipment manual for detailed installation and maintenance procedures
