SMC Precision Air Pressure Regulator Pilot Operated Low Pressure Precision with

Product Description:

The SMC AR425 to AR935 series represents a range of internally pilot-operated, relieving-type air pressure regulators. Within this series, the AR825, AR835, AR925, and AR935 sub-series stand out as part of the large-bore category, featuring port sizes that range from 1-1/4" up to 2". These regulators are specifically designed for demanding applications such as central compressor stations, high-flow mains, and multi-station centralized air supply systems.

Utilizing a pilot-operated mechanism, these regulators use the supply air itself to actuate the main valve. This design ensures significantly improved outlet stability, a lower pressure drop when operating at high flow rates, and minimal fluctuation in outlet pressure even when the inlet pressure varies. Such performance enhancements are notable when compared to traditional direct-acting regulators.

The product listing includes 14 distinct part numbers. These cover 1-1/4" and 1-1/2" AR825 and AR835 models, which also include gauge-equipped G versions, as well as 2" AR925 and AR935 models that have G versions as well. Additionally, there are 2" X218 semi-standard special configurations available.

For pressure range options, the high-pressure variants (denoted as 25: AR825/AR925) offer adjustability from 0.05 to 0.83 MPa. Meanwhile, the low-pressure precision variants (35: AR835/AR935) provide an adjustment range from 0.02 to 0.2 MPa. This broad spectrum of pressure control addresses the needs of both general pneumatic systems and specialized low-pressure precision applications, including electronics manufacturing, coating processes, and laboratory air supply.

Features:

The product is equipped with large bore ports sized at 1-1/4", 1-1/2", and 2", which are ideal for mains and multi-drop centralized supply systems. These sizes ensure efficient flow and connectivity for various applications.

Featuring an internal pilot relieving mechanism, the device automatically releases any excess outlet pressure to the atmosphere. This helps maintain optimal pressure levels and enhances safety during operation.

There are two available pressure ranges to suit different requirements: a high range from 0.05 to 0.83 MPa, and a low precision range from 0.02 to 0.2 MPa. This versatility allows for precise control in diverse environments.

The body of the unit is constructed from die-cast aluminum, offering robustness and durability for industrial plant use. The weight varies by model, with AR825 and AR835 weighing approximately 2.5 kg, while the AR925 and AR935 models weigh around 4.5 kg.

Models with a G suffix are shipped with an integrated panel pressure gauge from the G46 series, providing a clear and convenient local pressure reading for the user.

The X218 suffix denotes an SMC semi-standard special configuration. For detailed specifications and customization options, customers are advised to consult our sales team to ensure the product meets their exact needs.

A locking screw is incorporated on the adjusting handle to prevent accidental changes after the pressure has been set. This feature supports reliable and stable performance during use.

The product offers multiple thread options to accommodate various installation requirements, including Rc (PTF), NPT (F), and G thread types, all available upon request.

Applications:

Centralized compressor stations play a vital role in managing and reducing pressure along the main air lines. These stations ensure a stable and efficient supply of compressed air throughout the facility by regulating and optimizing pressure levels.

Utilizing high-flow compressed air mains enables plant-wide centralized air distribution. This approach supports a reliable and consistent air supply, which is essential for the smooth operation of various pneumatic systems across the manufacturing plant.

Automated assembly, packaging, and conveying lines with multiple stations benefit greatly from integrated compressed air systems. Such automation increases production efficiency and maintains precise control over complex manufacturing processes.

Pneumatic manipulators, large bore cylinders, and clusters of pneumatic grippers are commonly employed to handle tasks requiring precision and power. These components are essential in applications where repetitive and reliable motion is critical.

Facilities often incorporate spray booths, air blow-off stations, and high-volume process air points to support surface treatment, cleaning, and drying operations. The availability of ample compressed air volume ensures optimal performance in these processes.

Heavy industrial sectors, including mining, metallurgy, cement production, and power generation, rely extensively on robust compressed air systems. These industries demand durable and efficient pneumatic solutions to handle their rigorous operational requirements.

Original Equipment Manufacturer (OEM) machines within the textile, printing, paper, and packaging industries are designed to integrate compressed air components. This integration enhances machine functionality and contributes to overall production quality and reliability.
