The GRACO 902-20 Piston, Pinch, Lower is a precision-engineered component designed for use in the GRACO 902-20 Positive Displacement Pinch Action Dispense Valve. It is typically constructed from durable materials suitable for industrial environments and is intended to control the flow and dispensing of materials ranging from low to high viscosity, such as epoxies and metal-filled pastes. Its primary function is to ensure volumetric consistency and reliable shut-off within the dispensing system.

Key Features:

• Piston, Pinch, Lower
• 902-20, 0.090 (specific size may refer to orifice or piston diameter)
• Designed for use with GRACO 902-20 Positive Displacement Pinch Action Dispense Valve
• Precision fit for consistent material dispensing
• Designed for easy maintenance and cleaning (wetted parts are disposable)
• Fail-safe design to prevent material dumping in case of power failure
• Micrometer adjustment for precise volumetric control

Applications:
Used in industrial dispensing applications requiring precise, consistent dot-to-dot volumetric dispensing, such as in electronics, automotive, and manufacturing industries.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety of the dispensing system.
• Ensure the system is depressurized before installation or maintenance
• Follow all safety instructions and warnings in the GRACO manual
• Use only trained personnel for installation and maintenance
• Regularly inspect and replace disposable wetted parts as needed
