The SMC ITV2050-312N is an electro-pneumatic regulator designed for industrial systems that need compressed air pressure to be controlled by an electrical signal rather than by manual adjustment. It is part of SMC’s ITV1000/2000/3000 Series, a product family developed for stepless pressure control in proportion to an input signal. For automated machinery, this matters because pressure can become part of the control logic instead of remaining a fixed mechanical setting. That makes the ITV2050-312N suitable for packaging machines, assembly equipment, test benches, clamping systems, and other pneumatic applications where pressure must change accurately and repeatably during operation.
From SMC’s ordering structure, the model code ITV2050-312N can be decoded in a straightforward way. “2” identifies the 2000 type, “5” identifies the 0.9 MPa pressure-range class, “0” identifies 24 VDC power supply, “3” identifies a 0 to 10 VDC input signal, “1” identifies an analog monitor output of 1 to 5 VDC, “2” identifies the 1/4 port size, and the suffix “N” identifies NPT thread type. SMC’s web catalog also confirms that ITV2050-312N is a valid product in the ITV1000/2000/3000 regulator series.
A major commercial advantage of this regulator is that it supports programmable pressure control. In traditional pneumatic systems, pressure is often adjusted once with a manual regulator and then left unchanged. That approach is acceptable for basic air circuits, but it becomes inefficient when one machine must run different products, multiple process steps, or variable force conditions. With the ITV2050-312N, pressure can be adjusted electronically through a voltage signal, which allows the control system to store, repeat, and switch pressure values automatically. This is one of the main reasons electro-pneumatic regulators remain common in OEM machine building and automated production environments.

The 0.005 to 0.9 MPa pressure range is an important part of this model’s positioning. In the ITV family, SMC defines three standard positive-pressure classes: 0.1 MPa, 0.5 MPa, and 0.9 MPa. The ITV2050 belongs to the highest of those standard ranges, which gives it broader working flexibility than lower-range variants. In practical use, that makes the model suitable for pneumatic circuits where outlet pressure may need to cover a wide setpoint window, such as clamping, pressing, leak testing, fixture control, or other applications that benefit from electronically adjustable force.
The 0 to 10 VDC input signal is also commercially relevant. Many PLC analog output cards and industrial controllers use voltage-based command signals, so a regulator with this input format can usually be integrated directly into the machine without additional signal conversion hardware. That reduces wiring complexity and simplifies commissioning. The 1 to 5 VDC analog monitor output provides a feedback signal for supervision, diagnostics, or control-system verification, which is useful when the machine needs confirmation that the regulator is operating within the expected range.
Product Weight and Installation Value
| Feature | Practical Meaning |
|---|---|
| Approx. 350 g body weight | Light enough for compact machine integration |
| ITV2000 body size | Middle-size platform with practical flow capability |
| 1/4 NPT port | Suitable for many export-oriented and North America-oriented pneumatic installations |
| IP65 enclosure | Appropriate for typical industrial machine environments |
| 0 to 10 VDC command | Easy match for common controller architectures |
For quotation work, product listing, and logistics planning, the weight is one of the most requested specifications. SMC lists the ITV20 class at approximately 350 g, and the catalog states that this is the weight without brackets. Because the ITV2050-312N is an ITV2000-series unit, 350 g is the correct working net product weight for commercial descriptions and BOM use. This should not be confused with gross shipping weight, which will be higher once carton, label, and packaging materials are included.
The environmental specification is also useful for real machine design. SMC lists the ITV series with an IP65 enclosure rating and an ambient/fluid temperature range of 0 to 50°C without condensation. That means the ITV2050-312N is suited to general industrial automation environments where dust resistance and splash protection are necessary. It is not a specialist washdown or corrosive-environment device, but for standard factory applications it is a practical and established choice.
Typical Industrial Applications
| Application | Why ITV2050-312N Fits |
|---|---|
| Packaging machinery | Pressure can be changed automatically by recipe |
| Assembly equipment | Pressing or clamping force can be adjusted electronically |
| Leak testing | Repeatable regulated pressure improves test consistency |
| End-of-arm tooling | Gripping force can be tuned for different workpieces |
| Fixture systems | Pressure settings can be stored and recalled by the PLC |
| OEM machine building | Easier integration than a manual regulator |
In packaging machinery, pressure often needs to be adjusted according to product size, film type, or cycle mode. In assembly systems, excessive pneumatic force can damage components, while insufficient force can reduce process stability. In leak test equipment, repeatable pressure control directly affects result consistency. In each of these cases, the ITV2050-312N offers an advantage because it allows pressure to be controlled electrically, not manually. That reduces operator dependence and improves repeatability from one batch or cycle to the next. The regulator’s proportional-control design is intended for precisely this type of automated duty.
Another technical point worth noting is the ITV2000 platform size. Within SMC’s ITV family, the 2000 series occupies the middle position between the smaller ITV1000 and the larger ITV3000. This gives the ITV2050-312N a useful balance between compact dimensions and practical industrial capacity. For machine builders, that balance matters because it helps preserve cabinet or frame space without forcing a compromise to the smallest possible regulator size.
Performance Characteristics
| Characteristic | SMC Published Value |
|---|---|
| Linearity | ±1% F.S. or less |
| Hysteresis | 0.5% F.S. or less |
| Repeatability | ±0.5% F.S. or less |
| Sensitivity | 0.2% F.S. or less |
| Maximum supply pressure | 1.0 MPa for 0.5 MPa and 0.9 MPa types |
| Minimum supply pressure | Set pressure + 0.1 MPa |
SMC publishes a set of performance characteristics for the ITV series that explain why these regulators are used in controlled automation rather than only in simple air preparation duty. The catalog lists 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. It also lists a maximum supply pressure of 1.0 MPa for the 0.5 MPa and 0.9 MPa types, and a minimum supply pressure of set pressure plus 0.1 MPa. These figures indicate a regulator intended for stable proportional control under proper pneumatic supply conditions.
For buyers, the selection logic is simple. The ITV2050-312N is not the best choice for a basic air circuit that only needs one fixed pressure and no electrical control. In that situation, a conventional mechanical regulator is usually more economical. This model becomes valuable when the machine requires programmable pressure, repeatable setpoint control, PLC integration, and signal-based monitoring. In those situations, the higher initial component cost is often justified by better process consistency, faster setup, and easier automation.
