Proportional directional control valve VPWI

Product Description
The Festo VPWI is a highly dynamic piezo valve, stroke controlled and adjustable in different ways, offering a dynamic range of up to 180Hz . Its full graphic display allows programming of stroke limitation, adjustable incline, and actual value feedback for pressure or stroke. Equipped with food grade NSFH1 grease, this 3 way proportional directional control valve delivers precise and highly dynamic performance for demanding industrial applications.

Key Features & Advantages:

• Dynamic Range up to 180Hz: Generates extremely short operating times and a stable valve position, enabling highly responsive pneumatic control in demanding servo-pneumatic positioning systems .

• Full Graphic Display & Programmable Settings: The integrated 1.77″ TFT colour display with 128x160 pixel resolution provides clear visual feedback for programming stroke limitation, adjusting incline, and setting actual value monitoring for pressure or stroke, eliminating the need for external configuration tools .

• Multiple Adjustable Parameters (Stroke, C value, Flow Linearisation): Offers flexible tuning to match specific application requirements, from simple volume control to an MFC like function, significantly reducing commissioning time and inventory .

• Actual Value Output for Pressure or Stroke: Provides analogue output signals (0 10V or 4 20mA) for real time monitoring of either output pressure or valve stroke, enabling closed loop control and diagnostic capabilities .

• Hygienic Design – Food Grade NSFH1 Grease: Utilises food grade lubricant compliant with NSFH1 standards, making the VPWI suitable for food and beverage processing, pharmaceutical, and other hygienic applications where contamination must be controlled .
