The SMC ITV2050-322BL is an electro-pneumatic regulator built for applications where air pressure needs to be controlled by an electrical signal rather than by manual adjustment. It belongs to SMC’s ITV1000/2000/3000 series, a product family designed for stepless control of air pressure in proportion to an electric signal. SMC’s published series information highlights core control characteristics such as linearity within ±1% F.S., hysteresis within 0.5% F.S., and repeatability within ±0.5% F.S., which is why the ITV range is widely used in automated machinery instead of ordinary fixed-setting regulators.
What makes the ITV2050-322BL especially useful is its position within the ITV2000 platform. In the SMC series catalog, the ITV2050 model belongs to the 0.005 to 0.9 MPa pressure range group within the ITV2000 family. That gives it a wider usable pressure window than the lower-range ITV2010 or ITV2030 versions, making it more suitable for machines that need higher or more flexible controlled pressure. The same SMC series catalog shows that ITV2000 regulators are the mid-size class in the family and are intended for general industrial automation where 1/4 and 3/8 port sizes are common.
For the specific suffix 322BL, market listings consistently describe this model as a 24 VDC, 0 to 10 VDC input, switch output/NPN output, Rc thread, 1/4 port, flat bracket, and right-angle 3 m cable configuration. These details are repeated by industrial sellers that specialize in SMC pneumatic products. While the most authoritative series-level data comes from SMC’s own ITV catalog, these distributor listings are useful for decoding the exact commercial suffix when the public SMC part-detail page is not easily accessible.

A major strength of this regulator is that it allows pressure to become a programmable process variable. In a conventional pneumatic system, the operator adjusts the regulator manually and leaves it at a fixed setting. That works for simple air circuits, but it is inefficient in automated equipment that runs multiple products, changing clamping forces, or different pressure recipes. The ITV2050-322BL allows the machine controller to change pressure electronically through a 0 to 10 VDC analog input, so the same machine can shift pressure automatically according to process requirements. That is exactly the type of application the ITV series is intended for.
The 0.9 MPa pressure class is one of the most commercially important parts of this model. Within SMC’s ITV family, the 2050 designation belongs to the highest standard positive-pressure range in the ITV2000 group. This gives the regulator a broader control window for applications such as force control, clamping, pressing, leak testing, and process air regulation. It is a better fit than lower-range versions when the machine needs both fine regulation and higher available set pressure.
Weight and Installation Considerations
| Weight Reference | Value |
|---|---|
| SMC ITV20 series catalog weight | Approx. 350 g |
| Nex Instrument listing for ITV2050-322BL | 350 g |
| Typical shipping weight from reseller listing | Higher than net unit weight |
For your requirement to include product weight, the most defensible figure is approximately 350 g. SMC’s ITV-series catalog lists the ITV20 class at about 350 g, and a seller listing for the exact ITV2050-322BL gives the same 350 g product weight. That consistency is important. It means 350 g is a solid value for product descriptions, quotation sheets, website listings, and internal BOM work. It should be treated as net product weight, not packed shipping weight. Once the unit is boxed with protective material, the gross shipping weight will be higher.
The flat bracket and right-angle cable connector are also practical advantages. A flat bracket simplifies mounting on machine frames or panels, while the right-angle cable exit helps where installation space is tight and straight cable routing would be inconvenient. In real equipment design, those details matter because they reduce installation difficulty and improve cable management. This is especially useful in packaging machines, compact control cabinets, and modular assembly stations where pneumatic components are installed close together.
Typical Industrial Applications
| Application | Why ITV2050-322BL Is Suitable |
|---|---|
| Packaging machinery | Pressure can be changed automatically by recipe |
| Assembly equipment | Clamping and pressing force can be regulated electronically |
| Leak test systems | Stable regulated pressure improves consistency |
| Robotic tooling | Gripping force can be adjusted for different parts |
| Fixture systems | Pressure becomes programmable instead of manually reset |
| OEM machines | Easy integration with analog control architecture |
In packaging equipment, pressure often needs to vary by product format, film thickness, or sealing condition. In assembly systems, too much pneumatic force can damage parts, while too little force may reduce process reliability. In leak testing, repeatable pressure is directly related to repeatable test quality. The ITV2050-322BL helps in all of these cases because it allows the controller to command and manage pressure instead of relying on manual adjustment. That reduces setup time, lowers operator dependency, and improves consistency across production runs.
Another advantage is signal compatibility. The 0 to 10 VDC input used on this model fits many common PLC analog output modules and industrial controllers. That means the regulator can usually be integrated directly into standard voltage-based automation architectures without signal conversion hardware. The switch output / NPN output version is useful when the machine mainly needs status or control-state signaling rather than a continuous analog monitor signal. For many machine builders, that is a practical configuration because it supports straightforward electrical integration.
Performance and Environmental Suitability
| Characteristic | Published / Marketed 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 |
| Protection | IP65 |
| General operating concept | Stepless proportional pressure control |
SMC’s ITV series is not positioned as a basic air-line accessory. It is designed as a precision control component. The published series specifications show linearity within ±1% F.S., hysteresis within 0.5% F.S., repeatability within ±0.5% F.S., and sensitivity within 0.2% F.S. or less. Those values explain why the ITV line is common in automated manufacturing, where pressure needs to follow a controlled command and remain stable from cycle to cycle. For buyers comparing standard regulators with electro-pneumatic regulators, this is the key distinction: the ITV2050-322BL is not mainly about simple pressure reduction; it is about controlled pressure behavior.
The product family is also associated with IP65 protection, which is suitable for many mainstream industrial environments where dust and splash resistance are necessary. That does not make it a specialized washdown device for every harsh environment, but it does make it appropriate for general machine-building duty. In typical factory automation, that level of protection is more than adequate for regulators installed in panels, machine frames, or controlled production environments.
Selection Perspective
| Selection Point | Assessment |
|---|---|
| Good for fixed one-time pressure setting | Not the best choice |
| Good for programmable pressure control | Yes |
| Suitable for 0 to 10 V systems | Yes |
| Suitable for compact machine integration | Yes |
| Suitable for higher standard pressure range in ITV2000 | Yes |
| Good for OEM automation projects | Yes |
The SMC ITV2050-322BL is not the lowest-cost solution for a simple air circuit that only needs one constant pressure. A mechanical regulator would usually be cheaper for that job. This model becomes the better choice when the machine requires programmable pressure, stable repeatability, electrical control integration, and a compact but capable regulator body. For OEM equipment, semi-automatic machinery, and process-controlled pneumatic systems, those benefits often justify the higher component cost.
