The SMC ITV2050-31F2BL is an electro-pneumatic regulator engineered for industrial compressed-air systems that require electrical pressure control instead of manual adjustment. It belongs to SMC’s established ITV1000/2000/3000 series, a product family designed to deliver stepless pressure regulation in proportion to an electrical input signal. In practical machine design, that means the regulator can receive a command from a PLC, controller, or other automation hardware and convert it into a stable pneumatic output pressure, helping the machine maintain process consistency without repeated operator intervention.
The ITV2050 designation places this model in the ITV2000 size class and the 0.005 to 0.9 MPa pressure range category. SMC’s official catalog identifies ITV2050 as the 0.9 MPa range version within the ITV2000 family, and the same documentation lists the ITV2000 type as having an approximate unit weight of 350 g without brackets, an IP65 enclosure, and an operating temperature range of 0 to 50°C. These characteristics make the regulator suitable for use in packaging equipment, assembly systems, test benches, handling units, and general factory automation where pressure has to be controlled accurately and repeatedly.
One reason the ITV2050-31F2BL is commercially useful is that it turns air pressure into a controllable process variable. In older or simpler pneumatic systems, the regulator is often adjusted manually and then left fixed. That approach works only when the process does not change. In modern automated equipment, however, pressure often needs to vary according to product type, cycle stage, recipe, or quality requirement. An electro-pneumatic regulator solves that problem by allowing the machine controller to set the pressure value electronically. The ITV series is specifically intended for that kind of duty and is promoted by SMC as a compact, lightweight regulator family with integrated electronic control.

The catalog states linearity ±1.0% 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, ambient and fluid temperatures of 0 to 50°C, IP65 enclosure, and ITV20xx weight of approximately 350 g without brackets.
Product Weight
For users who need shipping, installation, or panel-layout reference data, the SMC ITV2050-31F2BL has an approximate product weight of 350 g without brackets, based on SMC’s official ITV2000-series specification. This weight is important in real engineering work because it affects mounting method, support design, manifold loading, and the overall mass of decentralized pneumatic assemblies. In compact automation systems, even a few hundred grams can matter when components are installed on moving frames, tight control panels, or modular machine sections.
The weight figure also reflects one of the ITV family’s design advantages: the product line is intentionally positioned as lightweight and compact, while still providing closed-loop electronic pressure control. That combination is useful because many electro-pneumatic devices with similar functionality can become awkward to integrate if they occupy too much space or add unnecessary mounting burden. The ITV2000 class maintains a good balance between functional capability and physical practicality.
Operating Principle
The ITV2050-31F2BL works by receiving an electrical command signal and converting that signal into a proportional air pressure output. Internally, the regulator uses pressure sensing and closed-loop valve control to compare the commanded value with the actual downstream pressure. It then adjusts the valve position continuously until the output pressure matches the target. This is the fundamental reason electro-pneumatic regulators are favored in automated systems: they do not merely “set and hold” pressure mechanically, but instead actively regulate pressure according to the control signal. SMC’s catalog explicitly describes the ITV series as controlling air pressure proportionally to an electric signal.
The official ITV specifications also indicate performance characteristics that support precision use, including linearity, hysteresis, and repeatability limits. Those figures matter because they describe how closely the output follows the command, how much difference appears between increasing and decreasing control directions, and how consistently the unit can reproduce the same pressure under repeated conditions. For machinery where air pressure influences force, sealing quality, gripping stability, or test repeatability, these characteristics are directly relevant to process quality.
Another useful point from the SMC documentation is that the regulator includes alarm-output configurations within the series, and the catalog explains that an alarm is generated if the set pressure is not reached or maintained for five seconds or more. That feature improves diagnostic value in automated equipment, because the control system can detect when actual pressure behavior deviates from the commanded target instead of leaving the fault unnoticed until product quality is affected.
Product Advantages
1. Electronic Pressure Control for Automated Machines
The main advantage of the ITV2050-31F2BL is that it allows pneumatic pressure to be controlled directly by automation hardware. This reduces manual setup work and makes it possible to store pressure values in recipes, machine programs, or process sequences. In systems with multiple product formats or different operating stages, that is a major efficiency benefit.
2. Broad 0.9 MPa Pressure Range
The ITV2050 model is the 0.005 to 0.9 MPa version in the ITV2000 class. That gives it a broader usable pressure range than the lower-pressure ITV2010 or ITV2030 variants. It is therefore more suitable for applications that need stronger actuator force, higher clamping pressure, or wider adjustment capability.
3. Stable Control Characteristics
With catalog values such as ±1.0% F.S. linearity, 0.5% F.S. hysteresis, and ±0.5% F.S. repeatability, the ITV series is designed for controlled and repeatable pressure output. These are not abstract brochure claims; they are the technical indicators that explain why the device is appropriate for pressure-sensitive industrial tasks.
4. Industrial Protection
The series is rated IP65, which improves its usability in general factory environments where dust and incidental water exposure are possible. This does not make the unit universal for every harsh-duty environment, but it does make it more practical than an unprotected control device for standard industrial equipment.
5. Compact and Lightweight Structure
The ITV2000 type combines a moderate footprint with an approximate 350 g weight. That makes it easier to mount in compact machine assemblies, pneumatic panels, and OEM modules without giving up electronic pressure-control capability.
Typical Applications
| Application | Typical Function of ITV2050-31F2BL |
|---|---|
| Packaging Equipment | Controls sealing pressure, blow-off pressure, and cylinder force |
| Assembly Machines | Provides programmable clamping or pressing pressure |
| Test Benches | Maintains repeatable pressure for leak or function tests |
| Material Handling Systems | Adjusts gripping pressure according to product type |
| General Automation Lines | Replaces manual regulators with signal-controlled pressure setting |
| OEM Machine Modules | Integrates pneumatic pressure directly into PLC logic |
These applications align closely with the ITV family’s intended role. SMC’s own materials cite uses such as pressure management for thrust control, which is a practical way of saying the regulator is suitable wherever controlled pneumatic force matters.
Integration and Engineering Value
From an engineering standpoint, the ITV2050-31F2BL is valuable because it simplifies the control architecture of pneumatic machines. Instead of relying on a manual regulator plus repeated operator tuning, the designer can integrate pressure setpoints into the machine software. That improves repeatability and makes machine behavior easier to document, validate, and reproduce across production runs. It also supports faster changeovers because pressure can be altered by the program instead of by mechanical readjustment.
From a maintenance standpoint, the series’ diagnostic and monitor-oriented features are also useful. SMC documentation notes alarm behavior when the set pressure is not achieved or maintained, which can help maintenance teams detect pneumatic problems earlier. Combined with the IP65 enclosure and compact design, this makes the product more than just a regulator; it becomes a practical control component in the broader machine system.
From a sourcing standpoint, the ITV family is not obscure. It is widely represented across SMC channels and industrial distributors, which generally indicates an established installed base and strong market familiarity. That reduces procurement risk compared with niche or poorly documented alternatives.
Conclusion
The SMC ITV2050-31F2BL is a compact electro-pneumatic regulator in the ITV2000 series, intended for electrically controlled air-pressure regulation in automated industrial systems. The ITV2050 model corresponds to the 0.005 to 0.9 MPa pressure range, and SMC’s official series specifications state that the ITV2000 type offers IP65 enclosure protection, 0 to 50°C operating temperature, and an approximate weight of 350 g without brackets. The same catalog also specifies control-performance figures such as ±1.0% F.S. linearity, 0.5% F.S. hysteresis, and ±0.5% F.S. repeatability, which are the technical basis for its use in precision pneumatic control.
For machine builders, integrators, and industrial users, this model is a sound choice when pneumatic pressure needs to be treated as a programmable process variable rather than a fixed manual setting. It is especially suitable for packaging, assembly, testing, and handling equipment where repeatability, compactness, and practical industrial protection are required.
