The GRACO 26B491 is a high-reliability, non-heated dispense valve designed for single-component sealant and adhesive dispensing applications. It features a stainless steel housing and is intended for use in automated and robotic systems where consistent, drip-free dispensing is required.

Key Features:

• Snuff-Back Dispense Valve
• 26B491
• Stainless steel housing, wear-resistant seals, hardened components
• Maximum working pressure: 4000 psi (28 MPa, 276 bar) for standard models; some configurations up to 5000 psi (34.5 MPa, 345 bar) for ball-seat valves (check specific model for exact rating)
• For use with GRACO Precision Swirl Valves; compatible with low to high viscosity materials
• Snuff-back action prevents dripping
• Maximizes dispense time while minimizing maintenance
• Reliable and consistent performance
• Easy repeatable mounting for robotic and automated applications
• Wear-resistant seals and hardened components for long life

Applications:
Single-component sealant and adhesive dispensing in automated and robotic manufacturing environments, suitable for low to high viscosity materials.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting for robotic and automated applications
• Use appropriate fittings for 1/4 in. NPT inlet and outlet ports
• Follow all safety and operational guidelines in the GRACO manual
• Regularly inspect seals and components for wear and replace as needed
