Snuf-Bak™ Dispense Valve Range

The 2600-041 Series Snuf-Bak® Dispense Valve is designed for fast and clean shut-off of thixotropic and cohesive materials such as viscous silicones, epoxies and urethanes. The all new design incorporates the trademark Snuf-Bak action of fluid materials in a small, compact KISS® Series valve body. The Snuf-Bak feature provides a suction-action when the valve closes to eliminate or reduce strings and fluid drips from the dispense tip.

The new 2600-041 Snuf-Bak Dispense Valve is only 1.5 inches (38 mm) square and 3.5 inches (89 mm) long and is rated for 4,000 psi (275 bar). The valve is double air actuated with two 1/8 NPTF ports for a 4-way pneumatic valve connection. The divorced-design fluid body has two 1/4 NPTF fluid inlet ports and a 1/4 NPTF dispense port to accept a wide variety of available nozzles.

The 2600-041 Dispense Valve has two user features. The body has two holes for #10 or M6 screw and two 1/4" dowel holes for accurate mounting. The valve may be mounted to robot tooling, automation fixtures or available manual handle assemblies. Also, the fluid suction volume can be controlled and locked in place with a set-screw adjustment.

The 2600-041 Snuf-Bak Dispense Valves are robotically, automatically and manually used to dispense 1-part epoxy, urethane, silicone, PVC and acrylic for bonding, gasketing, coating, potting and filling applications in aerospace, appliance, contractor, defence, electronics, filters, marine, medical, sporting goods, automotive, truck and bus assembly dispensing applications.
