EXPFLEX ITV Series Electro-Pneumatic Proportional Regulator is a high-tech control valve designed for precise, stepless, and dynamic air pressure control using electrical signals in industrial automation systems. The system adjusts the output line pressure instantly based on the electrical data (voltage or current) received from an external PLC or controller.
Operating Principle and Technology
The device operates on a closed-loop feedback mechanism:
  • Input Signal: A command signal (e.g., 0-10V or 4-20mA) is sent to the device from a PLC or analog card.
  • Air Supply: The internal supply solenoid valve opens to increase the output pressure.
  • Feedback: The integrated pressure sensor inside the regulator measures the output pressure in real-time and transmits it to the control circuit.
  • Correction: Internal valves continue to supply or exhaust air until the output pressure perfectly matches the input signal, then lock the pressure in place.
Technical Specifications and Wiring Diagram
The general technical structure of popular EXPFLEX models, such as the widely available ITV205-312S, is as follows:
  • Supply Voltage: DC 24V
  • Input Control Signal: DC 0-10 V (proportional voltage control)
  • Monitor Output Signal: DC 1-5 V (to report pressure status back to the PLC)
  • Operating Pressure Range: Generally 0.005 to 0.9 MPa (precise adjustment between 0.05 - 9 Bar)
  • Port Size: 1/4" Pneumatic Thread
  • Power Consumption: Very low due to its compact design (4W or less)
Standard Cable Wiring Colors:
  • Brown: DC 24V (+) Positive Supply
  • White: INPUT (0-10V Control Signal from PLC)
  • Blue: GND (-) Ground / Common
  • Black: OUTPUT (1-5V Status Feedback Signal to PLC)
Typical Application Areas

  • Laser Cutting Machines: Dynamically adjusting the pressure of auxiliary gases (Oxygen, Nitrogen) based on material thickness.
  • Tension Control Systems: Controlling the cylinder pressure that keeps web tension constant in paper, textile, or plastic packaging lines.
  • Robotics and Automation: Adjusting the precise gripping force of robot hands and controlling atomizing air in paint booths.
  • Test Benches: Applying gradual pressure profiles in leak-testing and durability-testing equipment.
