The SMC ITV2010-312L is a compact electro-pneumatic regulator designed to control compressed-air pressure in proportion to an electrical input signal. It belongs to SMC’s ITV1000/2000/3000 series, a product family developed for applications where stable, repeatable, and remotely adjustable pressure control is more effective than a conventional manual regulator. SMC’s official catalog describes the ITV series as a regulator for stepless control of air pressure in proportion to electrical signals, and distributor listings identify ITV2010-312L as a valid model in that series.
Within the ITV family, the ITV2010 model is the low-pressure version in the ITV2000 size class. SMC’s catalog places ITV2010 in the 0.001 to 0.1 MPa pressure range, making it appropriate for applications that require fine pressure control rather than higher-force pneumatic output. The same SMC documentation lists the ITV2000 body class as IP65 and gives an approximate weight of 350 g without options, which is the standard weight reference for this size group.
Model coding for this specific unit indicates a defined electrical and mechanical configuration. In the ITV1000/2000/3000 ordering structure, the code pattern shows that “2” corresponds to 0 to 5 VDC input, “3” corresponds to 1 to 5 VDC analog monitor output, and “L” indicates a right-angle cable connector option. The exact part number ITV2010-312L is also listed by industrial distributors, confirming that it is a market-recognized configuration rather than an improvised decoding exercise.
This model is well suited to automated systems where low-pressure air must be controlled accurately and repeatedly. In practical industrial use, that can include delicate clamping, light pressing, film handling, precision air blowing, small-force actuator control, test fixtures, and laboratory-style automation. The main value of the ITV2010-312L is that it allows the machine controller to adjust pressure electronically, which reduces manual setup, improves consistency across cycles, and makes process settings easier to store in recipes or control logic. These use cases are consistent with SMC’s series positioning and with the low-pressure range assigned to ITV2010.

Product Weight
For installation planning, transport reference, and machine-layout design, the SMC ITV2010-312L has an approximate product weight of 350 g without options. SMC’s official product literature states that the ITV20m0 class is approximately 350 g, while the ITV10 class is lighter and the ITV30 class is heavier. Since ITV2010 belongs to the ITV2000 body size, that 350 g reference applies here.
This weight matters more than it may appear at first glance. In compact automation systems, regulator mass affects mounting stability, bracket sizing, panel layout, and the overall weight of moving or modular subassemblies. A regulator that offers closed-loop electronic control while remaining around the 350 g level is easier to integrate than a larger separate arrangement built from a manual regulator, external transducer, and additional control hardware. SMC’s catalog also presents the ITV series as a compact product line intended to save space and reduce weight in machine design.
Operating Principle
The ITV2010-312L works by receiving an electrical command signal and converting that command into a proportional output pressure. In this model, the command signal is 0 to 5 VDC. The internal control circuit interprets the voltage level as a target pressure, then adjusts the regulator’s internal valve action until the measured downstream pressure matches the requested value. SMC’s official documentation describes the ITV series exactly in these terms: it controls air pressure steplessly in proportion to an electric signal.
This closed-loop method is what separates the ITV2010-312L from a manual pressure regulator. A manual regulator can only hold a mechanically adjusted setting until someone changes it. The ITV2010-312L can follow commands from the automation system in real time. That makes it useful for machines where different process steps require different low-pressure levels. For example, one stage may require gentle positioning pressure, while another may require a slightly higher holding pressure. In systems built around repeatability, that difference is not minor; it determines whether the process behaves consistently from cycle to cycle. The low-pressure range of ITV2010 is particularly relevant in applications where excessive force would damage the product or disturb process stability.
The regulator also provides a 1 to 5 VDC analog monitor output, which allows the control system to observe regulator behavior rather than just command it. That monitor signal can be used for diagnostics, process feedback, recipe verification, and alarm logic. SMC’s documentation notes the analog-output option in the ITV-series ordering structure, and this model’s code indicates that the monitor-output configuration is included.
Performance Characteristics
SMC publishes a set of core control-performance values for the ITV1000/2000/3000 series. These include linearity of ±1% F.S. or less, hysteresis of 0.5% F.S. or less, repeatability of ±0.5% F.S. or less, and sensitivity of 0.2% F.S. or less. The catalog also lists the ambient and fluid temperature range as 0 to 50°C and the enclosure protection as IP65. These are the technical indicators that make the product suitable for precise pneumatic control rather than rough adjustment duty.
In practical terms, good linearity means the output pressure follows the input signal in a predictable way. Low hysteresis means the response remains more consistent when the command signal rises and falls. Good repeatability means the same command tends to generate nearly the same output over repeated cycles. For low-pressure applications such as film transport, small-force clamping, or test-air control, these characteristics are often more important than maximum pressure capacity. They are the reason a regulator like the ITV2010-312L is chosen over a simpler manual device.
Design Advantages
One of the strongest design advantages of the ITV2010-312L is that it combines low-pressure precision, compact ITV2000 body size, and electrical integration in one standard component. In many machines, low-pressure control is the harder requirement because the process window is smaller and overpressure can quickly create defects. The ITV2010 model addresses that by offering the lowest standard positive-pressure range in the ITV2000 family, namely 0.001 to 0.1 MPa.
Another practical advantage is the right-angle cable connector, indicated by the L suffix. In real equipment, cable exit direction affects assembly convenience and service access. A right-angle connector can be preferable in tight panels or machine frames because it reduces the space required behind the unit and can make wiring routes cleaner. SMC’s ordering structure explicitly defines L as the right-angle cable connector option.
The IP65 enclosure is also important. Industrial equipment is rarely installed in ideal laboratory conditions. Dust, light moisture, and general factory contamination are common. IP65 does not mean unlimited environmental resistance, but it does make the regulator more suitable for general industrial use than an open or lightly protected control device. SMC’s official ITV-series specification lists IP65 for this product family.
Typical Applications
| Application Area | Typical Use of ITV2010-312L |
|---|---|
| Precision Assembly Equipment | Low-force clamping and positioning pressure control |
| Packaging Machinery | Gentle air blowing or film-handling pressure regulation |
| Inspection and Test Fixtures | Stable low-pressure air for repeatable testing conditions |
| Electronics or Delicate-Part Handling | Pressure control where excessive force must be avoided |
| OEM Automation Systems | PLC-based recipe control of low-pressure pneumatic functions |
| Laboratory or Bench Equipment | Fine electronic control of compressed-air output |
These application examples are consistent with the ITV2010 low-pressure range and with SMC’s description of the ITV series as an electro-pneumatic regulator for proportional pressure control.
Why Choose the ITV2010-312L
From an engineering perspective, the ITV2010-312L is a practical choice when the process requires fine low-pressure control rather than broad high-pressure capability. Its 0.001 to 0.1 MPa range fits applications where too much pressure is more dangerous than too little. The 0 to 5 VDC input makes it compatible with common analog-control outputs, while the 1 to 5 VDC monitor output supports feedback-oriented control architecture.
From a machine-building perspective, the product also offers a good physical balance. At approximately 350 g, with IP65 protection and a right-angle cable connector, it is suited to compact layouts where space, serviceability, and installation cleanliness all matter. The fact that the exact model appears in industrial distributor catalogs is also useful, because it indicates practical availability and a recognized commercial part number.
Conclusion
The SMC ITV2010-312L is a compact ITV2000-series electro-pneumatic regulator designed for applications that require low-pressure air control by electrical signal. Based on SMC’s official ITV-series data, it provides a 0.001 to 0.1 MPa pressure range, 24 VDC power supply, 0 to 5 VDC input, 1 to 5 VDC monitor output, IP65 protection, and an approximate product weight of 350 g without options. The L suffix identifies a right-angle cable connector, which improves installation flexibility in tighter equipment layouts.
For OEM builders, integrators, and industrial users, this model is a sound selection when low-pressure pneumatic control must be repeatable, programmable, and easy to integrate into a wider automation system. Its strongest value is in processes where gentle force, clean signal control, and compact mechanical design are more important than maximum output pressure.
