Product Overview
The SMC ITV1050-312L is a precision electro-pneumatic proportional valve (electro-pneumatic regulator) manufactured by SMC Corporation, a global leader in pneumatic and industrial automation control technology. This component functions as an electronically controlled pressure regulator that continuously modulates output air pressure in direct proportion to an analog electrical input signal (typically 0–10 V DC or 4–20 mA). Unlike conventional on/off solenoid valves, the ITV1050-312L employs a closed-loop feedback control circuit with an internal pressure sensor, enabling stepless, highly repeatable pressure regulation independent of supply pressure fluctuations or flow demand variations. It serves as a critical control element in industrial pneumatic systems requiring precise, dynamic pressure modulation, such as tension control, force-controlled actuation, and proportional pneumatic positioning.
