Product Overview
The SMC ITV2050-31F3BN3-Q is a high-precision electro-pneumatic proportional valve from the SMC ITV2000 series, engineered to deliver stepless, continuously variable pressure control proportional to an electrical input signal. Unlike conventional on/off solenoid valves, this unit employs a closed-loop electro-pneumatic pressure regulator design in which an internal pressure sensor continuously monitors the secondary (outlet) pressure and feeds it back to the control circuit, ensuring exceptional linearity, repeatability, and minimal hysteresis. The valve accepts a standard analog command signal (0–10 VDC or 4–20 mA, depending on configuration) and modulates the internal pilot mechanism to regulate output pressure with high resolution. Its compact, manifold-mountable body and integrated pressure display make it a preferred choice for precision pneumatic control loops in automated industrial machinery, where accurate force, tension, or flow regulation is critical to process quality.

Engineering Features & Advantages
- Precision Proportional Control: Closed-loop electro-pneumatic architecture delivers highly linear pressure output proportional to the command signal, with low hysteresis and excellent repeatability for demanding control loops.
- Integrated Feedback Sensing: An internal pressure sensor continuously corrects the output, compensating for supply fluctuations and load changes to maintain stable regulated pressure.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust solenoid actuation and durable spool/pilot construction.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original SMC OEM standards, ensuring drop-in interchangeability.
Typical Industrial Applications
Ideally suited for precision pneumatic tension and force control in web handling and converting lines, proportional pressure regulation in plastic injection molding and blow molding machines
