Product Overview
The SMC ITV1150-312L is a high-precision electro-pneumatic proportional valve (electro-pneumatic regulator) manufactured by SMC Corporation, a global leader in pneumatic and industrial automation technology. This component functions as a pressure control valve that continuously modulates its output pressure in direct proportion to an analog electrical input signal (typically 0–10 V DC or 4–20 mA). Unlike simple on/off solenoid valves, the ITV1150-312L employs a closed-loop feedback mechanism with an internal pressure sensor, ensuring highly stable and repeatable output pressure regulation independent of supply pressure fluctuations or downstream flow variations. It serves as a critical control element in industrial systems requiring precise, stepless air pressure regulation, such as tension control, force-controlled actuation, and proportional pneumatic positioning.
