What is the Graco 26B491 iQ Snuff Back Valve?

The Graco 26B491 is an iQ Snuff Back Valve designed for accurate dispensing of single-component adhesives and sealants in industrial production environments. This configuration features a 45° Outlet, Adjustable Snuff Back functionality, Remote Mount Solenoid, and ambient-temperature material capability for enhanced installation flexibility.

The adjustable snuff-back mechanism helps eliminate dripping and material stringing by slightly retracting material flow at the end of each dispense cycle. This improves application quality, reduces waste, and supports cleaner production processes.

Its remote-mounted solenoid configuration allows greater flexibility when integrating the valve into automated systems, robotic cells, and confined installation spaces where direct-mounted controls may not be ideal.
