Product Overview
The SMC ITV1030-312CL is a 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, the ITV1030-312CL modulates its internal poppet and exhaust mechanism to regulate secondary air pressure in direct proportion to a 0–10 V DC or 4–20 mA command signal, achieving stable, repeatable output pressure without the need for a separate pressure feedback loop in most installations. Its integrated pressure sensor and closed-loop control circuit continuously compare the setpoint against actual downstream pressure, correcting for supply fluctuations and flow-induced droop. This makes the unit a core control element in pneumatic process regulation, tension control, force-controlled actuation, and precision air-pressure management across automated industrial systems.
