Needle dispensing valve DELO-DOT RE

volumetricpneumatic actuator

The DELO-DOT RE pneumatic retraction valve strikes the balance between the repeatability and control of high-quality volumetric or jetting systems and the simple, direct dispensing of cartridges. After dispensing, the needle retracts to reverse adhesive flow. The resulting vacuum effect prevents dripping. Pneumatic retraction valve Bubble- and drip-free dispensing Good reasons why you should choose the DELO-DOT RE for the highest quality: Precise Dispensing: Bubble-free dispensing of liquids at volumes as low as 0.09 µl Process Accuracy: Maximum reproducible dispensing accuracy of up to 97% Retraction Effect: Prevents dripping Customer-Tailored Solutions: One-stop shop for high-tech adhesives, dispensing systems, and UV lamps Consulting Services: Our experts help to find a solution tailored to your requirements The valve dispenses adhesives bubble-free, at volumes as low as 0.09 µl with a standard deviation of less than 3%. This almost corresponds to the dosing consistency of high-quality jet valves. Therefore, it is capable of dispensing at significantly lower quantities than direct cartridge dispensing. Thanks to its small size and weight of just over 50 grams, DELO-DOT RE can be easily integrated into almost any production line. Its actuator and fluid system are separate, so that the valve does not have to be removed from the system when changing. In addition, the fluidics can be changed without tools, making assembly and disassembly easy. The retraction valve is ideal for applications in semiconductor and camera production due to its described properties.
