The SMC ITV2050-313N is an electro-pneumatic regulator engineered for industrial applications that require compressed air pressure to be controlled continuously by an electrical command signal. Instead of relying on manual adjustment like a conventional regulator, this model is designed to provide stepless control of air pressure in proportion to an electric signal, which makes it suitable for automated machinery, test equipment, packaging systems, assembly stations, and other pneumatic processes where pressure must change accurately during operation. SMC identifies the ITV family as a proportional pressure-control series and publishes key performance figures for the range, including linearity within ±1% F.S., hysteresis within 0.5% F.S., repeatability within ±0.5% F.S., and sensitivity within 0.2% F.S. under standard conditions.
Within the ITV product family, the ITV2050 belongs to the ITV2000 size class and the 0.005 to 0.9 MPa pressure-range group. SMC’s official catalog shows that the ITV2000 series is available in 1/4 and 3/8 port sizes, and that the ITV2050 designation corresponds to the 0.005 to 0.9 MPa pressure range rather than the lower 0.1 MPa or 0.5 MPa classes. This makes the model suitable for pneumatic systems that need a relatively broad usable pressure window while still remaining more compact than the larger ITV3000 platform.
For practical buyers and engineers, the attraction of the ITV2050-313N is straightforward: it allows a machine controller to adjust air pressure electronically as part of the control logic. That matters in systems where different products, recipes, fixtures, or cycle steps require different pressures. In a packaging machine, grip or sealing pressure may need to change between formats. In an assembly cell, clamping or pressing force may need to be tuned for different components. In a leak test station, pressure stability and repeatability are essential for reliable results. Because the ITV family is designed specifically for pressure output proportional to an electrical input, it is much better suited to these tasks than a simple manual regulator that is set once and left unchanged.

The product weight is one of the easiest specifications to confirm from SMC’s official documentation. In the catalog for the ITV1000/2000/3000 series, SMC states that the ITV20 class has an approximate weight of 350 g without options. Since the ITV2050-313N is part of the ITV2000 family, 350 g is the correct net-unit weight to use in product descriptions, quotations, internal BOMs, and general catalog work. This should be understood as the regulator body weight rather than shipping weight with packaging.
For electrical behavior, SMC’s official ITV-series catalog shows that the family supports both current-type and voltage-type input signals. In the standard specifications, SMC lists 4 to 20 mA, 0 to 20 mA, 0 to 5 VDC, and 0 to 10 VDC among the supported input styles, while the monitor-output section includes both 1 to 5 VDC analog output and 4 to 20 mA current-type analog output, as well as switch-output versions. In distributor descriptions for the ITV2050-313N, the model is specifically described as a unit with analog output 4 to 20 mA, sinking type, which is consistent with the output choices shown in the SMC family catalog.
That combination is commercially useful. A regulator with electrical command control and analog monitoring is easier to integrate into a PLC-driven or controller-based machine than a manual air regulator. It allows pressure to become a programmable process variable rather than a static maintenance setting. In practice, that reduces setup time, improves repeatability, and supports recipe-based production. Where machines must switch quickly between product variants or pressure setpoints, the ITV2050-313N can eliminate repeated manual adjustment and make the pneumatic circuit easier to standardize.
Why This Model Works Well in Automation
| Application Area | Functional Benefit |
|---|---|
| Packaging equipment | Pressure can change automatically with recipe selection |
| Assembly systems | Better control of clamp and press force |
| Leak test equipment | Improved repeatability of regulated pressure |
| Handling tools | Adjustable gripping pressure for different workpieces |
| OEM machinery | Easier PLC integration than manual regulators |
| Retrofit projects | Converts fixed-pressure circuits into programmable systems |
Another important technical characteristic is the regulator’s environmental suitability. SMC specifies the ITV series for an ambient and fluid temperature range of 0 to 50°C without condensation, and the enclosure rating is listed as IP65. That makes the ITV2050-313N appropriate for most general industrial machine environments where dust resistance and splash protection are necessary. It is not a specialist hygienic regulator for aggressive washdown environments, but for standard factory automation, enclosed equipment, workstations, and machine-mounted pneumatic systems, the protection level is solid.
The pressure capability of the ITV2050 family also gives it a clear place in system design. SMC lists the maximum supply pressure for the 0.5 MPa and 0.9 MPa classes as 1.0 MPa, and the minimum supply pressure as set pressure plus 0.1 MPa. That means the regulator is intended for systems with proper compressed-air supply margins rather than marginal inlet pressure conditions. In practical engineering terms, this helps maintain stable control performance and gives the ITV2050 range enough headroom for applications that require more than low-pressure regulation.
From a mechanical-selection perspective, the ITV2000 class is often the most balanced size in the family. The official SMC series overview shows the ITV2000 range positioned between the smaller ITV1000 and the larger ITV3000, and the public SMC series page identifies ITV2000 as the version with 1/4 and 3/8 connection-port classes and set pressure ranges up to 0.9 MPa. That makes it suitable for many machine-building applications where the user wants meaningful flow capability and a useful pressure range without moving to the physically larger 3000-size regulator.

A realistic buying assessment is that the ITV2050-313N is not the best choice for every air circuit. If a system only needs one fixed pressure and there is no requirement for remote control, monitoring, or recipe changeover, a standard mechanical regulator will usually be cheaper and simpler. The value of the ITV2050-313N appears when the machine needs programmable pressure, repeatable output, and electrical integration with automation hardware. In those cases, the SMC ITV family’s proportional-control behavior, published repeatability figures, and available analog-monitoring options make it a much stronger fit.
In summary, the SMC ITV2050-313N is a practical and technically mature electro-pneumatic regulator for industrial users who need precise pressure control as part of machine logic rather than manual setup. Its ITV2000 platform, 0.005 to 0.9 MPa range, IP65 enclosure, and approximate 350 g net weight make it suitable for packaging systems, assembly equipment, test stations, handling tools, and general automation projects. For commercial use, the safest weight figure to state is 350 g, and for technical positioning, the most accurate description is that this model belongs to SMC’s proportional ITV regulator family for stepless electronic pressure control.
