Description
The GRACO 802-20 is a positive displacement pinch tube dispense valve designed for precise, repeatable dispensing of materials ranging from very thin fluids to high-viscosity epoxies and metal-filled pastes. It is constructed with robust materials for industrial use and is intended for integration into automated dispensing systems for applications requiring dot-to-dot volumetric consistency.
Key Features:
- Positive displacement pinch tube dispense valve
- 802-20
- Industrial-grade materials; disposable wetted parts for easy maintenance
- Do not exceed 100 psi (6.9 bar) on operating system; 60 psi (4.1 bar) on dispense tube
- Accepts several sizes of pinch tubes for desired volumetric output; compatible with automated dispensing equipment
- Micrometer adjustment for precise shot size
- Disposable dispense tubes for easy maintenance and cleaning
- Fail-safe design to prevent material dumping in case of power failure
- Lightweight, compact design for easy integration
- Repeatable, accurate dispensing for dot or bead applications
Applications:
Ideal for low volume, single-component dispensing in industries such as electronics, automotive, and general manufacturing. Suitable for applications requiring precise dot-to-dot volumetric consistency, including adhesives, sealants, and pastes.
Installation Notes:
- Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
- Ensure only trained personnel install and operate the valve
- Do not exceed specified pressure limits on the operating system or dispense tube
- Use appropriate tools for installation and avoid sharp objects when handling U-cups
- Regularly replace disposable wetted parts for consistent performance and hygiene
- Consult the manual for detailed installation and maintenance procedures
