Detailed Product Introduction: New Original SMC ITV2050-31F3BN2 Electro-Pneumatic Proportional Regulator
1. Product Overview
The ITV2050-31F3BN2 is an original high-precision electro-pneumatic proportional regulator belonging to SMC ITV2000 series. It is also named electronic pressure regulator, which converts analog electrical control signals into stepless, proportional compressed air output pressure. This model adopts 4-20mA current input signal configuration, G1/4 port thread, built-in digital LED display, NPN alarm switch output and standard IP65 protection housing. Different from manual precision regulators, it realizes automatic continuous pressure adjustment through PLC industrial control signals without manual knob operation. It can stably maintain constant outlet pressure regardless of inlet air pressure fluctuation and flow variation. Widely applied in precision tension control, laser cutting equipment, coating spraying systems, semiconductor testing devices, injection molding auxiliary equipment, welding machinery and automated calibration platforms that require closed-loop precise pneumatic pressure control.
2. Main Functions
- Proportional electrical signal pressure conversion: Output air pressure changes linearly following 4–20mA analog input signal to achieve stepless continuous pressure regulation.
- Closed-loop pressure feedback control: Built-in high-sensitivity pressure sensor collects real-time outlet pressure data, automatically correct deviation to guarantee ultra-stable pressure output.
- Digital real-time pressure display: Onboard 3-digit LED screen shows actual output pressure value, supporting unit switching of MPa, kPa, bar and psi.
- Abnormal pressure alarm output: NPN open collector switch signal is triggered when actual pressure deviates greatly from preset value for fault prompt and equipment interlock protection.
- Internal preset pressure storage: 4 groups of fixed pressure values can be pre-stored for quick switching of different working pressure conditions.
- Automatic exhaust pressure relief: When input signal decreases, the valve automatically discharges redundant internal air to lower outlet pressure rapidly.
- Parameter lock function: All internal setting parameters can be locked to avoid accidental modification caused by vibration or misoperation.
