Product Description
The Festo VEAB is a high-precision, directly actuated 3-way proportional-pressure regulator that controls both vacuum and overpressure with a single valve, offering a pressure range from -1 bar to 6 bar with highly dynamic response for low flow rates . Featuring integrated piezo technology, this valve provides extremely short switching times, silent operation, and very low power consumption while optionally offering an IO Link® interface for advanced diagnostics and parameter customisation, making it ideal for electronics, life sciences, textiles, and battery production .
Key Features & Advantages:
Control Vacuum and/or Overpressure with a Single Valve: Unique ability to regulate both negative pressure (vacuum) and positive pressure in a single device, eliminating the need for separate components and simplifying system architecture across a regulation range of -1 bar vacuum to 6 bar positive pressure .
Highly Dynamic Piezo Technology for Low Flow Rates: Directly actuated piezo bending strip provides ultra-fast response with almost zero mechanical wear, delivering exceptional control accuracy even at low flow rates of ≤20 L/min, with near-silent operation and minimal heat generation .
IO Link® Interface for Advanced Features: Optional IO Link® communication enables customizable control parameters, real-time diagnostics (cycle counter, processor temperature, switching status), zero-point and two-point calibration, and parameter presets—significantly simplifying system integration and commissioning .
Flexible Installation – In-Line or Sub-Base Valve: Available as an in-line valve with QS-4 push-in fittings for 4 mm tubing or as a sub-base valve with flange connections, supporting multiple mounting options including through-holes, H-rail, or mounting plates .
Silent, Efficient & Sustainable Operation: Operates with virtually no audible noise (<62.5 dB(A)), very low power consumption (max. 1 /W), and minimal heat dissipation; piezo actuator ensures >300 million switching cycles for exceptional service life and reliability .
