The GRACO 181947 Seat Valve is a replacement part designed for use in GRACO air-powered diaphragm pumps. It is typically constructed from durable materials such as stainless steel or other robust alloys to withstand harsh industrial environments. The seat valve functions as a critical sealing component within the pump assembly, ensuring proper flow control and preventing backflow during operation.

Key Features:

• Seat Valve
• Designed for GRACO air-powered diaphragm pumps (specific models not listed in available sources)
• Critical sealing component for pump operation
• Reversible design (stainless steel seats are reversible per GRACO manual)
• Ease of maintenance and replacement
• Reliable performance in demanding industrial environments

Applications:
Used in GRACO air-powered diaphragm pumps for fluid transfer and metering in industrial, mining, agricultural, and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the equipment. Non-genuine parts may compromise pump efficiency and reliability.
• Inspect all components for wear or damage before installation
• Lubricate o-rings and place them in the groove on each valve seat
• Install the valve seat with the o-ring facing down into the outlet housing
• Follow torque specifications for reassembly (55 to 85 ft-lb or 75 to 115 N•m for caps)
• Clean all parts thoroughly before reassembly
• Replace worn or damaged parts as needed
