Product Description
The Festo VOVK is an extremely narrow miniature valve with a 5.9 mm grid dimension, specifically designed for applications where the MHA1 is too large . This 3/2-way normally closed (NC) valve offers very high performance with a wide pressure range from -0.9 bar for vacuum operation up to 7 bar, making it ideal for controlling small air flows in high-density configurations . Depending on the connection type, up to 20 valves can be connected in a row, providing exceptional component density for space-constrained applications .
Key Features & Advantages:
Extremely Narrow 5.9 mm Grid Dimension: At only 5.9 mm wide, this miniature valve enables unparalleled component density, allowing up to 20 valves to be mounted side-by-side in a single manifold assembly .
Variable Connection Concepts: Available in three connection configurations to suit different installation requirements: flanged connection underneath (VOVK-FB for manifold mounting up to 10 valves), flanged connection at the front (VOVK-FF for up to 20 valves in a row), and barbed fitting connection at the front (VOVK-Q3F for individual valve mounting) .
Very Low Power Consumption: Consumes only 0.5 W at 12 or 24 V DC, making it ideal for battery-operated and portable devices, with integrated LED and overvoltage protection circuitry .
Vacuum Capable & Wide Pressure Range: Operates from -0.9 bar (vacuum) up to 7 bar positive pressure, providing exceptional versatility for applications requiring both suction and blow-off functions in a single valve platform .
Fast Switching Times: Delivers switching times of ≤6 ms at pressures 0 < p < 6 bar and ≤13 ms under vacuum conditions (-1 < p < 0 bar) for responsive pneumatic control .
Extremely Small and Lightweight: The ultra-compact form factor and minimal weight make the VOVK suitable for portable and mobile applications where mass and space are critical constraints .
