Product Description
The Festo VTEP-8176050 is the world's first proportional valve terminal, combining ultra-compact design with high-precision piezo technology for closed-loop pressure and vacuum control . At less than 120 mm total width, this terminal supports up to 10 independent working channels, delivering extremely sensitive control down to less than 1 mbar with reproducibility as low as 0.3% FS . Available in 2, 3, or 5 valve positions with EtherCAT communication, the VTEP enables dynamic, precise, and energy-efficient pneumatic control for demanding industrial applications.
Key Features & Advantages:
World's First Proportional Valve Terminal: Combines closed-loop control of moderate air flow on up to 10 channels in an ultra-compact footprint, eliminating the need for multiple discrete proportional valves
Ultra-Compact Design: Fits 10 working channels into less than 120 mm overall width (119 mm for 5 valve positions), enabling high-density integration into space-constrained machines
Pressure and Vacuum Control: Available in two variants – P type for 0 to 6 bar positive pressure and PL type for -1 to 1 bar vacuum/positive pressure combination, covering a full 6 bar control range
Exceptional Precision and Repeatability: Delivers linearity of 0.9% FS, hysteresis of 0.4% FS, and reproducibility of <0.4% FS (standard pressure) or <0.3% FS (low pressure), with overall accuracy of 1.1% FS
Piezo Technology Benefits: Wear-free operation with no particle abrasion, no heat generation (ensuring stable control behaviour over time), extremely quiet operation, ultra-low power consumption, and minimal air consumption – can reduce compressed air usage by up to 50%
EtherCAT Real-Time Communication: Features 2x RJ45 EtherCAT interfaces with support for distributed clock function, enabling precise synchronisation of slave devices in the network. Firmware updates via FoE ("File Transfer over EtherCAT")
Integrated Pressure-Temperature Sensor per Channel: Each valve contains an embedded sensor and airflow control algorithm, providing closed-loop control to maintain target pressure automatically
"Target Reached" Status Signal: Similar to "motion complete" function in electric drive technology, each channel provides a "target reached" status for simplified control architecture
LinkedPorts Function: Allows control of multiple channels simultaneously, increasing maximum flow capacity for applications requiring higher throughput
Built-In Setpoint Curve Software: Enables precise millisecond-increment pressure profiles independent of the host controller's clock cycle, for complex pressure ramping applications
Modular and Expandable Valve Positions: Available with 2, 3, or 5 physical valve positions. Cover plates (code B) can be used to reserve positions, which can later be replaced with valve plates without changing dimensions or pneumatic connections
Individual Valve Replacement: Each valve plate is secured with two screws, allowing easy field replacement or reconfiguration without dismantling the entire terminal
Interchangeable Valve Types: Both P (positive pressure) and PL (pressure/vacuum) valve plates are mechanically interchangeable, offering flexibility for mixed applications
LED Status Indication: Each valve features an LED for immediate visual status feedback. Additional LEDs provide EtherCAT network status and load voltage diagnostics
Integrated Push-in Fittings: Pneumatic connections (QS-8 for supply/exhaust, QS-4 for working ports) are securely integrated into the manifold plate, reducing piping time and potential leak points
Clean and Sensitive Environment Compatible: Constructed with copper, zinc, and nickel-free materials, making it ideal for battery production, semiconductor manufacturing, and life sciences applications where metal ion contamination must be avoided
LABS Zone III Conformity: Complies with VDMA24364 Zone III for paint-wetting impairment substances, suitable for paint shop environments
RoHS Compliant: Manufactured with RoHS-compliant materials and NBR seals, meeting environmental standards
Reduced Energy Consumption: The combination of piezo technology and efficient control algorithms can reduce compressed air consumption by up to 50% compared to conventional solutions
Wide Operating Temperature Range: Functions reliably from 5°C to 50°C ambient temperature
