Product Description:
The SMC AR425 to AR935 series represents a line of internally pilot-operated, relieving-type air pressure regulators. These regulators are engineered specifically for heavy-duty industrial compressed-air systems that demand a stable outlet pressure alongside a high flow capacity. In contrast to direct-acting regulators, their pilot structure utilizes the supply air itself to control the main valve. This design ensures enhanced pressure regulation accuracy, smoother flow characteristics, and significantly reduced outlet-pressure fluctuations in response to changes in inlet pressure.
This product range includes 12 commonly used part numbers divided into four sub-series: AR625, AR635, AR825, and AR835. The port sizes for these regulators vary from Rc 3/4" up to Rc 1-1/2". Customers can choose between two pressure ranges: a standard 0.05–0.83 MPa (25 type) and a low-pressure option of 0.02–0.2 MPa (35 low-pressure type). Additionally, units labeled with a "G" come equipped with an integrated panel pressure gauge, while a mounting bracket model B25P is available as an optional accessory.
These regulators find extensive applications across various industrial settings. They are commonly employed in compressor stations, central compressed-air lines, automated production lines, pneumatic manipulators, and OEM machine packages. Their robust construction and reliable performance make them an ideal choice for maintaining consistent air pressure in demanding environments.
Features:
The regulator features a pilot-operated design, which ensures a much more stable outlet pressure compared to direct-acting regulators. This design also makes the regulator less sensitive to fluctuations in inlet pressure, providing consistent performance.
It incorporates an internal relieving mechanism that automatically releases any excess outlet pressure to the atmosphere. This functionality maintains a constant pressure in the downstream line, enhancing safety and reliability.
Constructed with a die-cast aluminum body, the regulator is both lightweight and durable. The protected bonnet and chamber design contribute to excellent heat dissipation, making it well-suited for demanding factory floor environments.
The device offers two adjustable pressure ranges to accommodate different requirements: from 0.05 to 0.83 MPa (designated as type 25) and from 0.02 to 0.2 MPa (type 35, which is a low-pressure precision model).
Available port sizes include 3/4", 1", 1-1/4", and 1-1/2". Customers can also select from Rc (PTF), NPT (F), and G thread options upon request, providing flexibility for various installation needs.
For enhanced usability, an optional pressure gauge (marked with a G suffix, from the G46 series) and a mounting bracket (model B25P) are available. These accessories offer clear local pressure readings and facilitate easy retrofitting.
Additionally, a locking screw on the adjusting handle helps prevent accidental tampering and pressure drift after the desired setting has been established, ensuring stable and reliable operation over time.
Technical Parameters:
Applications:
Air compressor stations along with central FRL units, which include filters, regulators, and lubricators, play a crucial role in ensuring clean and controlled compressed air supply.
Branch pressure regulation is essential for automated assembly, packaging, and conveying lines to maintain optimal pneumatic performance and operational efficiency.
Pneumatic actuators such as air cylinders, grippers, pneumatic chucks, and vacuum generators are widely used to provide precise motion control and gripping functions in various industrial applications.
These components are also integral in machine tools, welding booths, spray painting systems, air blow-off processes, and purging points, where reliable and accurate air control is necessary.
OEM machines across a range of sectors including food and beverage, textile, electronics, semiconductor, and packaging industries depend on these pneumatic solutions for enhanced productivity and reliability.
Moreover, secondary pressure reduction and precision control are applied on high-flow centralized air mains to ensure consistent pressure levels and efficient air management throughout the system.
