The SMC ITV2030-312N is an electro-pneumatic regulator designed for precise electronic pressure control in industrial automation systems. It belongs to the SMC ITV1000/2000/3000 series, a well-established product family used when compressed air pressure must be set remotely, adjusted automatically, or stabilized more accurately than with a manual regulator. SMC’s web catalog lists ITV2030-312N under the ITV electro-pneumatic regulator series, confirming it as a standard cataloged model.
Unlike a conventional pressure regulator that relies on manual adjustment, the ITV2030-312N converts an electrical input signal into proportional output pressure. This makes it suitable for modern machinery where pressure settings need to change according to recipes, product formats, machine cycles, or PLC commands. In practical use, this type of regulator is widely selected for pneumatic clamping, air blowing, tension control, actuator force adjustment, leak testing, and test benches where repeatable air pressure directly affects process stability and product quality. SMC family documentation identifies the ITV2000 range as a compact, electronically controlled regulator platform with environmental protection up to IP65 and a normal operating temperature range of 0 to 50°C.

SMC’s public series documents provide the core family specifications used above, including the ITV20 body weight of approximately 350 g without options, IP65 enclosure, and 24 VDC current consumption of 0.12 A or less. The SMC family catalog also shows that the ITV2000 series standard port size is 1/4 only in the referenced catalog version. Public distributor listings for ITV2030-312N commonly decode the suffix as 0 to 10 VDC input, 1 to 5 VDC analog monitor output, 1/4 port, and without cable connector. That suffix mapping is useful in practice, but final procurement should still follow the latest official ordering confirmation.
Detailed Product Introduction
The SMC ITV2030-312N is intended for users who need stable and controllable air pressure in automated equipment. In many factories, pneumatic pressure is not just a utility value but an active process parameter. It influences clamping force, cylinder output force, nozzle pressure, sealing pressure, test pressure, and handling stability. If pressure drifts or varies from one operator to another, product quality becomes inconsistent. That is why electro-pneumatic regulators such as the ITV2030-312N are increasingly preferred over manual regulators in automated systems.
A major strength of this model is that it allows pressure to be controlled by an electrical reference signal rather than by a hand-adjusted knob. In a PLC-based machine, the controller can send a command value and the regulator adjusts the output pressure accordingly. This makes it possible to store recipes, automate changeovers, and fine-tune force or airflow without physical manual intervention. In production environments with multiple product sizes or variable operating steps, this is a practical advantage because it reduces setup time and improves repeatability.
The ITV2000 family is also valued for control quality. SMC’s catalog for this series specifies linearity within ±1% full span, hysteresis within 0.5% full span, repeatability within ±0.5% full span, and temperature characteristics within ±0.12% full span per °C. These figures explain why the series is used in precision pneumatic applications where users need more than basic air regulation. When pressure accuracy affects sealing results, pressing force, or controlled airflow, that level of control performance becomes commercially important.
Another practical benefit is compact size and moderate weight. The ITV20 family weight is listed at approximately 350 g without options, which is light enough for machine mounting, compact manifolds, and panel integration. For OEMs and system integrators, this reduces mechanical burden and simplifies bracket design. The product family is also designed for industrial use, with IP65 protection stated in the catalog, which supports installation in many machine environments where dust and water spray resistance are important. Even so, good engineering practice still applies: cable routing, fitting sealing, and exhaust-side noise or relief measures should be considered during installation.
Typical Industrial Applications
| Application | Why ITV2030-312N Is Suitable |
|---|---|
| Pneumatic clamping systems | Enables precise and repeatable gripping or holding force |
| Leak testing equipment | Supports stable pressure setting for more consistent test conditions |
| Air blow and nozzle control | Allows pressure optimization for different products or cleaning stages |
| Packaging machinery | Helps adjust actuator force and pneumatic timing according to product format |
| Assembly stations | Makes recipe-based pressure changes easier through electronic control |
| Robotic end-of-arm tooling | Provides compact regulated pressure for grippers and handling circuits |
| Test benches and labs | Improves pressure control accuracy compared with manual regulators |
In clamping and holding applications, the regulator can reduce the risk of over-pressurizing delicate products while still maintaining adequate force. In test systems, it helps stabilize pressure input so measurement conditions are more consistent. In packaging or assembly lines, different product sizes often require different air pressures, and a regulator like the ITV2030-312N allows those values to be changed directly from the control program. These are practical reasons why electro-pneumatic regulators are common in flexible manufacturing systems.
Why ITV2030-312N Is a Valuable Choice
The value of the SMC ITV2030-312N lies in the combination of electronic controllability, compact form, and stable pneumatic performance. For machine builders, it supports automation logic and recipe management. For maintenance teams, it reduces dependence on manual adjustments and helps standardize machine setup. For end users, it can improve process consistency, reduce changeover time, and support better quality control in pneumatic operations.
Another point in its favor is family maturity. The ITV series has been established in the industrial market for many years, and SMC remains one of the most recognized names in pneumatic automation. That does not automatically mean every suffix variant is interchangeable, but it does mean the platform is widely understood by engineers, integrators, and maintenance personnel. In practical procurement terms, that lowers selection risk compared with obscure or poorly documented alternatives.
Selection Note
One technical note should be kept clear. The part number ITV2030-312N is confirmed as a valid SMC catalog item. The family-level specifications such as 350 g weight, 0.005 to 0.5 MPa pressure range, 1.0 MPa maximum supply pressure, IP65 enclosure, and 24 VDC family power specification are well supported by SMC series literature. The more detailed suffix interpretation often shown by distributors indicates 0 to 10 VDC input, 1 to 5 VDC monitor output, 1/4 port size, and without cable connector, but for final order placement it remains prudent to confirm that suffix definition against the current official ordering matrix or the actual product label.
Conclusion
The SMC ITV2030-312N is a practical and technically capable electro-pneumatic regulator for applications requiring remote and repeatable pressure control. As part of the ITV2000 family, it offers a published approximate weight of 350 g, IP65 protection, 0 to 50°C operating conditions, and a 0.005 to 0.5 MPa control range for the relevant pressure version. These characteristics make it suitable for machine automation, process control, assembly systems, test equipment, and pneumatic applications where electronic pressure adjustment improves consistency and operating efficiency.
