The GRACO 26B490 is a high-reliability, non-heated, direct mount solenoid valve designed for single-component sealant and adhesive dispensing applications. It features a stainless steel housing and is engineered for use in robotic and automated systems, offering consistent performance and minimal maintenance.

Key Features:

• Snuff-Back Dispense Valve
• 26B490
• Stainless steel housing, wear-resistant seals, hardened components
• Maximum working pressure: 4000 psi (28 MPa, 276 bar) for standard models; up to 5000 psi (34.5 MPa, 345 bar) for ball-seat configurations (note: 26B490 is not a ball-seat valve, but some sources list 345 bar/5000 psi for stainless steel housing; confirm with manual for exact rating)
• For use with GRACO Precision Swirl Valves; compatible with low to high viscosity materials
• Snuff-back action to prevent dripping
• Reliable and consistent performance
• Easy, repeatable mounting for robotic and automated applications
• Maximizes dispense time while minimizing maintenance costs and effort
• Wear-resistant seals and hardened components for long life

Applications:
Single-component sealant and adhesive dispensing in industrial, manufacturing, and automated environments. Ideal for applications requiring precise, drip-free dispensing of 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
• Follow manufacturer guidelines for inlet and outlet port connections (1/4 in. NPT inlet ports, 45° outlet port)
• Use compatible materials and check for wear-resistant seals and hardened components for long service life
• Regularly inspect and maintain seals and moving parts to prevent leaks and ensure consistent performance
