Bestselling Original New Electro-Pneumatic Regulator SMC ITV2050-333N High Performan ce

The SMC ITV2050-333N is an electro-pneumatic regulator developed for industrial systems that require compressed air pressure to be controlled by an electrical signal rather than by manual adjustment. It belongs to SMC’s established ITV1000/2000/3000 regulator family, a range designed for stepless pressure control in proportion to an electrical input. SMC’s official ITV documentation describes the series as a proportional pressure-control solution with compact construction, IP65 protection, and performance figures such as linearity within ±1% F.S., hysteresis within 0.5% F.S., and repeatability within ±0.5% F.S. for the standard electro-pneumatic regulator family.

From a product-selection standpoint, the ITV2050 base designation is the most important part of the code. In SMC’s official series table, ITV205m is the ITV2000-size regulator with a 0.005 to 0.9 MPa set-pressure range. That places it in the higher standard pressure class within the ITV2000 platform, above the 0.1 MPa and 0.5 MPa versions. This is significant because it gives the regulator a wider usable working range for machine builders and maintenance engineers who need one regulator platform to cover multiple pneumatic force requirements.

Public distributor data for the exact ITV2050-333N part number shows it as a valid commercial model in the ITV family, and one industrial catalog listing identifies it as a 2000 type, 24 V DC model in the 3/8 connection class, while the family documentation confirms that ITV2000 regulators are offered in the 1/4 and 3/8 port-size range. Because reseller databases sometimes expose configuration fields differently, the safest technical reading is to treat ITV2050-333N as a 2000-size, higher-pressure ITV regulator in the 3/8 class and verify the final detailed suffix against the nameplate or quotation when exact signal/output coding is critical.

Product Overview

One of the most important specifications for commercial and engineering use is the product weight. SMC’s official ITV documentation states that the ITV20 class has a weight of approximately 350 g without brackets, and the same family weight note is repeated in multiple ITV catalog references. Distributor data for the exact ITV2050-333N also points back to the ITV20 family weight class rather than a heavier or lighter custom body, so 350 g is the correct working net product weight for catalog descriptions, BOMs, quotations, and website listings. This figure should be treated as the regulator body weight, not gross shipping weight with packaging.

The value of the ITV2050-333N is easiest to understand in real machine applications. A traditional mechanical regulator is acceptable when pressure is set once and rarely changed. However, many automated machines do not work that way. Packaging systems may need different pressures for different film types or product sizes. Assembly equipment may require different clamp forces for different components. Test benches may need controlled, repeatable pressure changes across multiple stages of a test sequence. In those cases, a proportional regulator such as the ITV2050-333N allows pressure to become a programmable process variable rather than a fixed maintenance setting. That is the main reason electro-pneumatic regulators are widely used in modern automation.

Why This Model Is Useful in Automation

The 0.005 to 0.9 MPa range makes this regulator more versatile than lower-range variants. In practical terms, this means the ITV2050-333N can be used for a wider set of jobs, from relatively light pressure-control duties up to more demanding force-related applications. SMC’s series documentation also shows the ITV205m performance curves and flow behavior in the 0.9 MPa class, confirming that this model family is intended for meaningful industrial-duty pressure regulation rather than only light pneumatic trimming.

Another reason the ITV2050-333N remains commercially attractive is its balance of size and capability. The ITV2000 platform sits in the middle of the ITV family. It is larger and more capable than the smallest ITV1000 models, but more compact than the ITV3000 class. That balance matters in actual equipment design, because machine builders often need a regulator that offers practical flow and pressure range without consuming excessive mounting space. SMC’s series literature presents the ITV2000 family exactly in that role, making it a common choice for general OEM machinery, handling systems, and pneumatic process-control assemblies.

Performance Characteristics

The published performance figures are one of the strongest reasons to choose this product family. According to SMC’s ITV documentation, the regulator series offers 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 are not marketing decoration. They indicate a component intended for controlled automation, where pressure output must track an electrical input with reasonable precision and stability. For buyers comparing manual regulators with electro-pneumatic regulators, this is the main difference: the ITV2050-333N is not just a pressure-reduction device, but a control component.

Environmental suitability is also relevant. SMC specifies the ITV family with IP65 protection and an ambient/fluid temperature range of 0 to 50°C without condensation. That makes the ITV2050-333N suitable for many standard industrial environments where dust resistance and splash protection are necessary. It is not a specialized hygienic regulator for aggressive washdown conditions, but for mainstream factory automation, enclosed machine frames, and controlled industrial installations, the protection level is appropriate.

In practical purchasing work, this model is especially attractive for users who want to standardize machines around electrically controlled pressure rather than operator-dependent adjustment. Once pressure is controlled from the machine program, setup can be faster, recipes can be stored and recalled, and repeatability improves across operators and shifts. That has direct value in packaging, assembly, inspection, and testing equipment. It also reduces the risk that a machine will drift simply because someone has manually changed a regulator setting. This is why the ITV family is frequently chosen in OEM designs and retrofit upgrades.

Commercial Handling and Weight Reference

For international trade and logistics, it is worth separating net product weight from gross packed weight. The regulator itself is approximately 350 g, but actual shipping weight will depend on carton size, protective material, labels, and quantity per package. For a technical product introduction, 350 g is the correct figure to publish. For freight-cost estimation, it is prudent to allow additional packaging weight instead of treating 350 g as final courier weight.

Product Summary

In summary, the SMC ITV2050-333N is a practical electro-pneumatic regulator for users who need programmable, repeatable, electrically controlled air-pressure regulation in a mid-size industrial package. Its ITV2000 platform, 0.005 to 0.9 MPa pressure range, IP65 protection, and approximate 350 g net weight make it well suited to automated machinery where pressure must be managed as part of the control strategy rather than left as a fixed manual setting. For commercial use, the most reliable weight figure to state is 350 g, and for technical selection, the most important point is that this model belongs to SMC’s higher-range ITV2000 regulator family.
