Product Description
The Festo VEAB is a high-precision proportional-pressure regulator that controls both vacuum and overpressure with a single valve—highly dynamic in the range of -1 bar to 6 bar with low flow rates, ideal for electronics, life sciences, textiles, and battery production . This 3 way piezo /valve offers extremely short switching times, silent operation, and very low heat generation, delivering maximum performance for demanding compact applications .
Key Features & Advantages:
Control Vacuum and/or Overpressure with a Single Valve: Unique ability to regulate both negative and positive pressure in a single device, eliminating the need for separate vacuum and pressure control components .
Highly Dynamic Piezo Technology – Silent & Efficient: Directly actuated piezo bending strip provides ultra-fast response, near-zero mechanical wear (>300 million switching cycles), and virtually silent operation with low heat generation .
Selectable Performance Classes with Four Presets: Choose from four predefined application-specific performance classes that provide the optimum control combination: balanced control, low overshoot, highly dynamic, or high pneumatic resistance .
IO-Link® Features: Customizable Parameters & Diagnostics: Optional IO-Link® interface enables customizable control parameters, real-time diagnostics (cycle counter, temperature, switching status), 2 point calibration, and easy parameter presets .
Flexible Installation – In-Line or Sub-Base: Available with QS push-in fittings for 4 mm tubing (in-line) or as a sub-base valve; supports mounting via through-holes, H-rail, or mounting plates; IP65 protection, weight approx. 70–85 g .
