ITV1050-01F2N: Electro-Pneumatic Regulator, The Pressure Control Expert for Precise Analog Signal Regulation
2026-02-25
Product Positioning
The ITV1050-01F2N is an electro-pneumatic regulator from SMC’s ITV1000 Series, capable of continuously and steplessly controlling compressed air pressure based on an electrical input signal. It precisely converts input electrical signals (such as 4-20mA current or 0-10V voltage) into a corresponding output pneumatic pressure, achieving high-precision, high-response pressure regulation. It is ideal for automation scenarios requiring remote pressure control or precise adjustment of force or speed, such as welding control, painting equipment, tension control, and precision assembly.
Core Highlights: Electronically Controlled Pneumatics, Precise and Stepless
Electro-Pneumatic Control, Pressure Follows the Signal
By using an input electrical signal (current or voltage), it enables stepless, continuous adjustment of the output air pressure, replacing traditional manual regulators and enabling remote automated control.
High Precision and Sensitivity
Sensitivity is as high as 0.2 kPa (for the 100 kPa specification), responding acutely to minute signal changes.
Linearity is within ±1% F.S., and hysteresis is within 0.5% F.S., ensuring a highly consistent linear relationship between output pressure and input signal, with excellent repeatability.
Selectable Set Pressure Range
This model corresponds to a pressure range of 0.1 MPa (the ITV1050 designation represents the 0.1 MPa specification), suitable for low-pressure precision control needs. The same series also offers 0.5 MPa and 0.9 MPa specifications.
IP65 Enclosure Rating for Environmental Adaptability
With an IP65 enclosure rating, it offers excellent dust and water resistance, making it suitable for harsh environments commonly found in general industrial settings.
Oil-Free Lubrication Design
The ITV1000 series uses a non-lube type (no grease) design, preventing oil mist contamination and making it suitable for clean environments.
Pressure Maintenance on Power Failure
If a power failure occurs while pressurized, the valve temporarily maintains the output pressure. This enhances system safety by preventing equipment damage or workpiece ejection caused by sudden pressure loss.
Multiple Monitoring Output Options
Analog output (e.g., DC1-5V) or switch output is available, allowing pressure status feedback to higher-level control systems like PLCs for closed-loop control.

Operating Principle
The ITV1000 series utilizes a closed-loop control principle:
- Input Signal: An electrical signal (e.g., DC4-20mA) is sent to the internal control circuit.
- Comparison and Control: The control circuit compares the input signal with the actual output pressure fed back by the internal pressure sensor.
- Valve Actuation: Based on the deviation signal, it drives either the supply solenoid valve or the exhaust solenoid valve.
- Pressure Adjustment: Opening the supply valve increases output pressure; opening the exhaust valve decreases output pressure.
- Stable Output: This continues until the output pressure is proportional to the input signal, at which point the valves close, maintaining a stable pressure.
This closed-loop control ensures the output pressure always precisely follows the input signal, unaffected by fluctuations in the air supply or changes in the load.
Application Scenarios
- Welding Control: Precise control of welding gun electrode force ensures consistent weld quality.
- Painting Equipment: Remote adjustment of atomizing air pressure for spray guns adapts to different paints and workpieces.
- Tension Control: Precise tension control for winding materials (paper, film, wire).
- Precision Assembly: Control of press-fitting force, adjustment of gentle gripping force.
- Medical Equipment: Precise air pressure regulation for ventilators and anesthesia machines.
- Energy Saving Management: Dynamically adjusting system pressure based on demand, achieving supply-on-demand.
Summary: The Precision Bridge from Analog Signal to Pneumatic Pressure
The ITV1050-01F2N electro-pneumatic regulator serves as the intelligent interface connecting electronic control systems and pneumatic actuators. Its high-precision, high-sensitivity closed-loop control capability accurately converts a standard 4-20mA current signal into a pneumatic output pressure within 0.1 MPa, enabling remote, stepless pressure regulation. The IP65 enclosure rating and oil-free design allow it to adapt to a wide range of industrial and clean environments, while the pressure maintenance function on power failure enhances system safety. Choosing the ITV1050-01F2N means equipping your automation system with a precise, reliable, and intelligent “electro-pneumatic conversion core,” making pressure control as simple, accurate, and controllable as adjusting volume—a key technological component for enhancing equipment automation levels and process stability.
