Product Description:
The SMC AR425 to AR935 series represents a line of internally pilot-operated, relieving-type air pressure regulators. These devices are specifically engineered for heavy-duty industrial compressed-air systems where maintaining a stable outlet pressure and achieving a high flow capacity are critical. Unlike direct-acting regulators, the pilot structure in this series utilizes the supply air itself to control the main valve. This design results in enhanced pressure regulation accuracy, smoother flow characteristics, and significantly reduced fluctuations in outlet pressure even when the inlet pressure changes.
This product range includes 12 commonly used part numbers categorized into four sub-series: AR625, AR635, AR825, and AR835. The regulators come with port sizes ranging from Rc 3/4" to Rc 1-1/2". Customers can choose between two pressure ranges: 0.05–0.83 MPa (referred to as the 25 type) and 0.02–0.2 MPa (known as the 35 low-pressure type). Additionally, models labeled with a "G" suffix are equipped with a panel pressure gauge, while an optional mounting bracket B25P is also available.
These regulators find extensive applications in various industrial settings, including compressor stations, central compressed-air pipelines, automated production lines, pneumatic manipulators, and OEM machine packages. Their robust design and reliable performance make them an ideal choice for demanding air pressure regulation needs in complex manufacturing and processing environments.
Features:
The regulator features a pilot-operated design, which provides a much more stable outlet pressure compared to direct-acting regulators. It remains largely unaffected by fluctuations in the inlet pressure, ensuring consistent performance.
This model incorporates an internal relieving mechanism that automatically releases any excess outlet pressure into the atmosphere. This function helps maintain a constant pressure in the downstream line, enhancing system reliability.
Constructed with a die-cast aluminum body, protected bonnet, and chamber, the regulator is both lightweight and capable of efficient heat dissipation. These characteristics make it especially suitable for demanding factory floor environments.
There are two adjustable pressure ranges available for this regulator. The first range covers 0.05 to 0.83 MPa, while the second, a low-pressure precision type, spans 0.02 to 0.2 MPa. This versatility allows it to be used in various applications requiring precise pressure control.
Port size options include 3/4", 1", 1-1/4", and 1-1/2". Thread types such as Rc (PTF), NPT (F), and G threads can also be provided upon request, accommodating diverse piping standards and installation requirements.
For improved usability, an optional pressure gauge (denoted by the G suffix, G46 series) and a mounting bracket (B25P) are available. These accessories provide clear, local pressure readings and facilitate easy retrofitting to existing systems.
Additionally, the regulator is equipped with a locking screw on the adjusting handle. This feature prevents accidental adjustments and pressure drift after the desired setting has been established, ensuring stable operation over time.

Applications:
Air compressor stations and central FRL (filter–regulator–lubricator) units play a crucial role in maintaining the efficiency and reliability of pneumatic systems. These central units ensure clean, regulated, and lubricated air supply throughout the facility.
Branch pressure regulation is essential in automated assembly, packaging, and conveying lines to maintain consistent performance. Proper pressure control at these branches helps optimize the operation of various pneumatic components and ensures smooth production processes.
Pneumatic actuators encompass a wide range of devices including air cylinders, grippers, pneumatic chucks, and vacuum generators. These actuators are vital for automation tasks, enabling precision movement and handling in industrial settings.
Various industrial applications such as machine tools, welding booths, spray painting areas, air blow-off stations, and purging points rely on pneumatic solutions. These applications demand precise air control to achieve high-quality results and operational safety.
Original Equipment Manufacturer (OEM) machines in sectors like food and beverage, textile, electronics, semiconductor, and packaging industries integrate pneumatic technology to enhance their productivity and reliability. Customized pneumatic components meet the specific needs of these diverse industries.
Secondary pressure reduction and precision control are critical on high-flow centralized air mains. These controls ensure that downstream equipment receives air at the required pressure levels, contributing to the overall stability and efficiency of the pneumatic system.
