Product Overview
The SMC ITV2050-31F2N3 is a high-precision electro-pneumatic proportional valve (electro-pneumatic regulator) from SMC’s ITV series, engineered to deliver continuously variable, stepless pressure control proportional to an analog electrical input signal. Unlike conventional solenoid valves that provide only on/off switching, this unit modulates its internal poppet and exhaust mechanism to maintain an output pressure that tracks the command signal in real time, achieving closed-loop pressure regulation without the need for a separate feedback controller. The valve is a process and pneumatic control component, not a pump, and is designed for inline installation within compressed air circuits where accurate, repeatable pressure setting is critical. Its compact body, integrated pressure sensor, and electrical signal interface make it a preferred choice for industrial automation systems requiring dynamic pressure profiling, soft-start/soft-stop control, and remote setpoint adjustment via PLC or analog controller.

Engineering Features & Advantages
- Precision Proportional Control: Continuously variable output pressure tracks the analog command signal, enabling fine metering and repeatable pressure regulation rather than simple on/off switching.
- Closed-Loop Stability: An internal pressure sensor provides real-time feedback, compensating for supply fluctuations and load changes to hold the set pressure accurately.
- Fast Dynamic Response: Quick response to command signal changes supports soft-start, soft-stop, and dynamic pressure profiling in automated processes.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with a robust body and sealed pneumatic construction.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original SMC OEM standards for drop-in service.
Typical Industrial Applications
This electro-pneumatic proportional valve is widely deployed in plastic injection molding machines for clamp and injection pressure control, CNC machine tools and automated assembly stations for precision air actuation, packaging and web-tensioning systems requiring dynamic pressure regulation, and general factory automation where remote or PLC-driven pneumatic pressure setpoints are needed. It is also suited to semiconductor and electronics manufacturing equipment demanding stable, repeatable low-pressure control.
