Product Overview
The SMC 25A-ITV2050-312CS is a high-precision electro-pneumatic proportional regulator from the SMC ITV series, engineered to deliver stepless, infinitely variable pressure control in response to an analog electrical input signal. Unlike conventional pressure regulators that rely on manual adjustment, this unit utilizes an internal closed-loop feedback system with a pressure sensor and proportional solenoid to continuously compare the commanded setpoint against actual downstream pressure, adjusting the internal valve spool to maintain accurate output regulation. The 25A prefix denotes an SMC special specification variant, while the ITV2050 body indicates a 1/4-inch ported regulator with an integrated pressure display and analog command interface. This device serves as a critical control element in pneumatic process loops, enabling remote setpoint programming, electronic pressure profiling, and seamless integration with PLC or DCS-based automation architectures.

Engineering Features & Advantages
- Precision Proportional Control: The closed-loop electro-pneumatic architecture delivers highly repeatable output pressure that tracks the analog command signal with minimal hysteresis, enabling accurate electronic pressure regulation in dynamic process loops.
- Remote Setpoint Programmability: Accepts analog voltage or current commands from PLC, DCS, or dedicated controllers, allowing full remote operation and integration into automated pressure profiling sequences without manual intervention.
- Integrated Pressure Feedback: An internal pressure sensor continuously monitors downstream output, providing real-time closed-loop correction that compensates for supply pressure fluctuations and downstream flow variations.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust spool and solenoid construction designed to withstand the rigors of 24/7 pneumatic process control.
- Direct Fit Replacement: Precision-manufactured to original SMC specifications for direct replacement, minimising downtime and eliminating fitment issues.
Typical Industrial Applications
This electro-pneumatic proportional regulator (process & pneumatic valve) is widely used in industrial hydraulic power units, machine tools, presses, and general automation systems where reliable, precise performance is required.
