About Dymax 826 Disposable Fluid Path Pinch Tube Valve

The pneumatically operated Dymax 826 Pinch Tube Dispensing Valve handles low to high viscosity materials with ease and is particularly capable at dispensing thicker, stringy materials. The valve obtains its precision from lockable controls that facilitate the adjustment of three critical parameters: the flow rate through the valve, the level of tube closure, and suck-back.

The Dymax 826 Pinch Tube Dispensing Valve features an easily changeable, disposable fluid path that carries materials from the material reservoir to the dispensing tip. The disposable fluid path is valuable when dispensing materials which are curing, or reactive, or abrasive. It makes is easier to change to a different material without extensive valve cleaning, or if your protocol requires a change for different material batches.

An in-built suck-back feature prevents the formation of material droplets at the end of the dispensing tip, avoiding dripping and mess when working with stringy or low viscosity materials.

The dispensing valve can be integrated into an automated dispensing system or paired with a dispensing controller and a material reservoir to create a bench-top dispensing system.

Operation

Model 826 Pinch Valve User Guide

The valve is opened to its adjustable stop by an air pressure pulse supplied by a valve controller. A spring assists with the closure of the upper piston (A) immediately after the supply of air is stopped, pinching the tube, preventing more material from passing into the valve.

An additional lower, blunt ended piston is pushed into position by a further spring, creating suck-back and preventing material from running on.
