Rc1-1/2" Pneumatic Regulator 0.02-0.2 MPa Low Pressure Precision Air Pressure Regulator with Die-cast Aluminum Body

Product Description:

The SMC AR425 to AR935 series consists of internally pilot-operated, relieving-type air pressure regulators. Within this series, the AR825, AR835, AR925, and AR935 sub-series are classified under the large-bore segment. These models feature port sizes ranging from 1-1/4" up to 2" and are specifically designed for use in central compressor stations, high-flow main lines, and multi-station centralized air supply systems.

The pilot-operated mechanism in these regulators uses the supply air itself to actuate the main valve. This design provides significantly improved outlet stability, reduces pressure drop during high flow conditions, and minimizes outlet fluctuations when there are variations in the inlet pressure. In comparison to direct-acting regulators, the pilot-operated types offer enhanced performance and reliability.

This product listing includes a total of 14 part numbers. It covers 1-1/4" and 1-1/2" models in the AR825 and AR835 series (which also include gauge-equipped G versions), as well as 2" models in the AR925 and AR935 series (also with G versions). Additionally, there are 2" X218 semi-standard special configurations available. The high-pressure variants (designated with 25: AR825/AR925) have an adjustable pressure range from 0.05 to 0.83 MPa. Meanwhile, the low-pressure precision models (designated with 35: AR835/AR935) have an adjustable range from 0.02 to 0.2 MPa, making them suitable for both general pneumatic systems and precise low-pressure applications such as electronics, coating, and laboratory air supplies.

Features:

The product is designed with large bore ports, including sizes of 1-1/4", 1-1/2", and 2". These ports are suitable for mains and multi-drop centralized supply systems, ensuring efficient and versatile connectivity.

This device incorporates an internal pilot relieving mechanism which automatically vents any excess outlet pressure to the atmosphere. This feature helps maintain stable pressure levels and enhances operational safety.

There are two available pressure ranges to choose from: a high precision range of 0.05 to 0.83 MPa, and a low precision range of 0.02 to 0.2 MPa. This flexibility allows users to select the pressure range that best fits their application requirements.

The body of the product is constructed from die-cast aluminum, offering durability and robustness for industrial environments. Depending on the model, the weight is either 2.5 kg for AR825/835 or 4.5 kg for AR925/935, making it suitable for heavy-duty plant use.

Units with the G suffix come equipped with a panel pressure gauge from the G46 series. This feature provides a clear and convenient local pressure reading, enhancing user monitoring capabilities.

The X218 suffix indicates a semi-standard special configuration by SMC. Customers interested in this customized option should contact the sales team to confirm specific details and specifications.

To prevent accidental adjustments after setting, the product includes a locking screw on the adjusting handle. This ensures stability and maintains the desired pressure settings during operation.

For connection versatility, various thread options are available upon request, including Rc (PTF), NPT (F), and G threads. This accommodates different piping standards and installation preferences.

Applications:

Central compressor stations play a crucial role in managing air pressure throughout the main air lines. These stations ensure efficient and reliable pressure reduction, maintaining optimal performance across the entire system.

High-capacity compressed air mains support plant-wide centralized air supply systems. This setup allows for consistent delivery of compressed air to various parts of the facility, enhancing operational efficiency and reducing energy consumption.

Automated production lines, including assembly, packaging, and conveying systems with multiple stations, rely heavily on compressed air technology. These automated lines increase production speed and accuracy while minimizing manual labor.

Pneumatic equipment such as manipulators, large bore cylinders, and clusters of pneumatic grippers are integral to modern manufacturing. These devices provide precise handling and movement for diverse industrial applications.

Specific applications include spray booths, air blow-off stations, and other high-volume process air points, where compressed air supports tasks requiring consistent, powerful airflow for cleaning, drying, or coating processes.

Heavy industries like mining, metallurgy, cement production, and power plants depend on robust compressed air solutions to handle demanding operational environments, ensuring reliability and safety.

Additionally, original equipment manufacturer (OEM) machines used in textile, printing, paper, and packaging industries benefit from specialized compressed air systems tailored to their unique manufacturing requirements.
