The SMC ITV2030-312L3 is an electro-pneumatic regulator designed for applications that require precise pneumatic pressure control through an electrical command signal. It belongs to SMC’s ITV1000/2000/3000 series, a product family developed to control air pressure steplessly in proportion to an electric signal. This makes the regulator suitable for automated machinery, test systems, assembly equipment, packaging lines, and other industrial applications where pressure must be adjusted accurately and repeatedly without manual intervention.
Within this family, the ITV2030-312L3 is part of the ITV2000 size class, which is commonly used where a compact body, stable control performance, and practical integration with PLC or analog control systems are required. SMC’s published family data identifies the ITV2000 class as having an approximate weight of 350 g without options, an IP65 enclosure rating, and an ambient and fluid temperature range of 0 to 50°C. These characteristics make the regulator suitable for many general industrial environments where space is limited but reliable pneumatic control is still necessary.
Unlike a conventional manual air regulator, the ITV2030-312L3 allows pressure setpoints to be established electronically. That means a controller can change outlet pressure during operation according to machine logic, product recipe, or process stage. In real industrial use, this capability is valuable in systems where gripping force, blowing pressure, sealing pressure, test pressure, or actuator force must be changed frequently and consistently. Instead of relying on an operator to make repeated manual adjustments, the regulator supports automatic control and better repeatability from cycle to cycle. SMC describes the ITV series as a regulator that controls air pressure in proportion to an electric signal, and that is the core operating concept of this model.

The ITV family documentation states that the series provides stepless control of air pressure in proportion to an electrical signal, supports IP65 enclosure protection, and lists ITV20x0 weight as approximately 350 g without options. Distributor listings for the exact model ITV2030-312L3 also identify it as an ITV2000 series electro-pneumatic regulator.
Product Function and Operating Principle
The SMC ITV2030-312L3 is designed to bridge the gap between electronic control systems and pneumatic output. Its function is straightforward in concept but highly useful in automated equipment: an electrical signal is sent to the regulator, and the regulator converts that signal into a proportional air pressure output. Internally, the device uses an electronic control circuit, pressure sensing, and valve modulation to regulate outlet pressure in a closed-loop manner. This allows the regulator to increase or decrease output pressure automatically until the actual pressure matches the target value commanded by the control system. SMC’s official series literature explains this control concept and identifies the ITV family as electro-pneumatic regulators for proportional pressure control.
This operating principle is useful in machinery where the required pressure changes during operation. For example, one stage of a machine may require a lower clamping pressure to position a part gently, while a later stage may require higher pressure to hold or process the part securely. In a manual system, the operator would need to adjust a regulator by hand. With the ITV2030-312L3, those pressure changes can be handled automatically through the machine controller. This improves consistency, shortens changeover time, and reduces dependence on operator skill.
Another practical advantage is the regulator’s compatibility with modern automation design. ITV regulators are widely used where PLCs or industrial controllers already generate analog control signals. That makes integration simpler than building a custom control arrangement from multiple separate devices. Instead of combining a manual regulator, additional transducers, and external correction logic, engineers can use an electro-pneumatic regulator as a more direct solution for pressure control. This improves wiring clarity and often reduces commissioning time.
Design Characteristics and Industrial Value
A major reason the ITV2030-312L3 is commercially and technically valuable is that it combines compact size, electronic proportional control, and industrial-grade enclosure protection in one unit. SMC’s ITV family documentation describes the products as lightweight, compact, and designed for industrial use. That matters because many machine builders must place components inside crowded cabinets, pneumatic panels, or equipment frames where space is limited. A regulator that can provide high functional value without a large footprint has clear design advantages.
The approximate 350 g weight of the ITV2000 class is also relevant in machine design. It is light enough for compact mounting arrangements while still being substantial enough for industrial service. In decentralized pneumatic modules, moving fixtures, or densely packed control assemblies, the physical characteristics of each component matter. A regulator that remains relatively light while offering closed-loop pressure control is easier to integrate than a larger or heavier alternative.
The IP65 enclosure rating is another important point. In many factory environments, components are exposed to dust, fine particles, and occasional splashing water. While IP65 does not make the regulator suitable for every harsh chemical or washdown application, it does mean the device is better protected than open control equipment. For general industrial automation, that is a useful level of environmental protection and helps expand the range of practical installation locations.
Typical Applications
| Industry or Equipment | How ITV2030-312L3 Is Used |
|---|---|
| Packaging Machinery | Regulates seal pressure, blowing pressure, and holding pressure |
| Assembly Equipment | Controls pneumatic force for pressing, clamping, and positioning |
| Electronics Manufacturing | Provides stable low-force air pressure for delicate operations |
| Test Benches | Maintains repeatable pneumatic conditions for leak or functional testing |
| Material Handling Systems | Adjusts gripper or actuator pressure remotely |
| General Automation | Enables recipe-based or stage-based pressure control |
These applications align with the ITV family’s intended role as a proportional electro-pneumatic regulator. Because the pressure setting can be controlled electrically, the device is particularly useful wherever machines must run multiple products, multiple process stages, or multiple force levels within one control system.
Why It Is a Practical Choice
From a sourcing and engineering perspective, the ITV2030-312L3 is a practical choice for several reasons. First, it comes from SMC, one of the most recognized manufacturers in pneumatic automation, which generally means broad market familiarity, available documentation, and strong parts ecosystem support. Second, it belongs to the established ITV family, which is already widely used for proportional pressure control. Third, the regulator offers a useful balance between performance and installation convenience: it is compact, IP65-rated, and designed specifically for pressure control by electrical input.
For OEM machine builders, that means easier integration into new equipment. For maintenance teams, it means a standardized and recognizable product family that is easier to identify and replace. For end users, it means more stable pressure control, less manual adjustment, and better process repeatability. In production environments where pressure variation can affect final product quality, these are not minor benefits. They can directly influence scrap rate, machine stability, and setup efficiency.
Conclusion
The SMC ITV2030-312L3 is a compact ITV2000-series electro-pneumatic regulator built for applications that require air pressure to be controlled proportionally by an electrical signal. It is suitable for machine automation, pressure-sensitive assembly processes, packaging systems, and industrial test equipment. Based on SMC’s official ITV series data, the ITV2000 class provides IP65 enclosure protection, supports an ambient and fluid temperature range of 0 to 50°C, and has an approximate weight of 350 g without options.
In practical terms, this model is a solid choice when the goal is to replace manual adjustment with stable, electronically controlled pneumatic pressure. Its value is strongest in systems where pressure must be changed automatically, maintained consistently, and integrated into a broader control architecture. That is exactly the operating space where the SMC ITV series is designed to perform.
