Model 826 disposable fluid path valve (pinch valve) features adjustable suck-back control to provide clean shut-off for tacky, stringy materials, and prevents material drool from forming at dispense tip with low viscosity fluids. Ensures accurate and consistent part-to-part shot volume. Disposable fluid path technology protects fluids from contamination and air entrapment, while facilitating rapid material changeover with minimal clean-up. Suitable for low-to-high viscosity materials. Valve possesses flow control and over-stroke adjustment that permit fluid deposits ranging from micro liter shots to continuous beads.
