Product Overview
The SMC ITV2050-31F2BN3-Q is a high-precision electro-pneumatic proportional valve from the SMC ITV2000 series, engineered to deliver continuously variable, stepless pressure control proportional to an analog electrical input signal. Unlike conventional solenoid on/off valves, this unit integrates a proportional solenoid actuator, a precision spool and poppet metering assembly, and an internal pressure feedback sensor that continuously compares output pressure against the command signal to maintain exceptional linearity and repeatability. The valve functions as an electronic pressure regulator within pneumatic circuits, converting a 0–10 VDC or 4–20 mA command into a corresponding regulated air pressure output. Its compact modular body, threaded port connections, and bracket-mountable housing make it a direct-fit solution for OEM and MRO replacement in automated industrial systems requiring accurate, closed-loop electro-pneumatic pressure regulation.

Engineering Features & Advantages
- Precision Proportional Metering: The proportional solenoid and precision spool assembly deliver stepless pressure output that tracks the analog command signal with high linearity, low hysteresis, and excellent repeatability for critical pneumatic control loops.
- Closed-Loop Pressure Feedback: An integrated pressure sensor continuously monitors output and corrects for supply fluctuations and downstream load changes, ensuring stable regulated pressure without manual re-adjustment.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust valve body, wear-resistant spool and seat geometry, and protection against typical plant air contamination.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original SMC ITV2000 series OEM standards, including port layout, bracket mounting, and electrical connector interface.
- Fast Dynamic Response: Quick actuation and settling characteristics support high-cycle automated processes requiring rapid, accurate pressure changes.
