Low Pressure Pneumatic Regulator 0.02-0.2 MPa Rc3/4" SMC AR635-06 Air Relief Valve

Product Description:

The SMC AR425 to AR935 series represents a line of internally pilot-operated, relieving-type air pressure regulators tailored for demanding industrial compressed-air systems. These regulators are engineered to provide stable outlet pressure and accommodate high flow capacities, making them ideal for heavy-duty applications. In contrast to direct-acting regulators, the pilot-operated design utilizes the supply air itself to control the main valve. This innovative approach ensures enhanced pressure regulation accuracy, smoother flow characteristics, and significantly reduced outlet-pressure fluctuations even when there are variations in the inlet pressure.

This product range includes 12 popular part numbers spread across four distinct sub-series: AR625, AR635, AR825, and AR835. The models offer port sizes ranging from Rc 3/4" up to Rc 1-1/2", catering to various installation requirements. Customers can choose between two pressure ranges to suit their needs: 0.05–0.83 MPa for the standard 25 type, and 0.02–0.2 MPa for the 35 low-pressure type. Additionally, units labeled with a "G" come equipped with a panel pressure gauge for convenient monitoring, while a mounting bracket model B25P is available as an optional accessory.

These regulators are extensively utilized across multiple industrial scenarios, including compressor stations, central compressed-air distribution lines, automated production lines, pneumatic manipulators, and original equipment manufacturer (OEM) machine packages. Their robust design and reliable performance make them an essential component in ensuring efficient and precise air pressure control within complex compressed-air systems.

Features:

The regulator features a pilot-operated design, which provides a much more stable outlet pressure compared to direct-acting regulators. This design also ensures that the regulator remains largely unaffected by fluctuations in the inlet pressure.

It incorporates an internal relieving mechanism that automatically vents any excess outlet pressure to the atmosphere. This function helps maintain a consistent downstream line pressure at all times.

Constructed with a die-cast aluminum body, the regulator includes a protected bonnet and chamber. This design results in a lightweight product with excellent heat dissipation, making it well-suited for use in demanding factory floor environments.

The regulator is available in two adjustable pressure ranges: 0.05 to 0.83 MPa for the standard model, and 0.02 to 0.2 MPa for the low-pressure precision type (model 35).

Multiple port sizes are offered, including 3/4", 1", 1-1/4", and 1-1/2". Additionally, thread options such as Rc (PTF), NPT (F), and G threads can be provided upon request to meet various installation requirements.

For enhanced usability, an optional pressure gauge (denoted by the G suffix, G46 series) and a mounting bracket (model B25P) are available. These accessories allow for clear local pressure readings and facilitate easy retrofitting.

A locking screw is installed on the adjusting handle to prevent accidental tampering and to avoid any unintended pressure changes once the desired setting has been established.

Applications:

Air compressor stations and central FRL (filter–regulator–lubricator) units are essential components in many industrial pneumatic systems. They provide the necessary air preparation to ensure clean, regulated, and lubricated air supply for various applications.

Branch pressure regulation plays a crucial role in automated assembly, packaging, and conveying lines. It helps maintain consistent pressure levels, ensuring that machines operate smoothly and efficiently without interruptions or pressure fluctuations.

Pneumatic actuators such as air cylinders, grippers, pneumatic chucks, and vacuum generators are widely used in industrial automation. These devices convert compressed air energy into mechanical motion, enabling precise control of movements and handling of components.

In addition to actuators, pneumatic systems are also employed in machine tools, welding booths, spray painting, as well as air blow-off and purging points. These applications rely on controlled air flow for cleaning, cooling, and material handling processes.

OEM machines across various sectors, including food and beverage, textile, electronics, semiconductor, and packaging industries, utilize pneumatic technology for enhanced reliability and performance. Customized pneumatic solutions cater to the specific needs of these diverse industries.

Lastly, secondary pressure reduction and precision control are critical on high-flow centralized air mains. These functions ensure that the downstream equipment receives air at the desired pressure and flow rate, optimizing the overall efficiency and safety of the pneumatic system.
