SMC AR625-06G Air Regulator with Gauge Rc3/4" Pilot Pressure Reducing Valve 0.05-0.83 MPa for Pneumatic Automation Systems

Product Description:

The SMC AR425 to AR935 series represents a range of internally pilot-operated, relieving-type air pressure regulators specifically engineered for heavy-duty industrial compressed-air systems. These regulators ensure a stable outlet pressure and support high flow capacity, making them ideal for demanding applications. In contrast to direct-acting regulators, the pilot-operated design utilizes the supply air itself to control the main valve. This mechanism provides enhanced pressure regulation accuracy, smoother flow characteristics, and significantly reduces outlet-pressure fluctuations even when the inlet pressure varies.

This product range includes 12 widely used part numbers distributed across four sub-series: AR625, AR635, AR825, and AR835. The port sizes available span from Rc 3/4" up to Rc 1-1/2", accommodating various installation requirements. Customers can choose between two pressure ranges: 0.05–0.83 MPa (known as the 25 type) and 0.02–0.2 MPa (referred to as the 35 low-pressure type). Units labeled with a "G" come equipped with a panel pressure gauge, and there is an option to add the B25P mounting bracket for easier setup.

These regulators are extensively applied in multiple industrial settings including compressor stations, central compressed-air lines, automated production lines, pneumatic manipulators, and OEM machine packages. Their robust design and reliable performance make them essential components in modern pneumatic systems.

Features:

The pilot-operated design ensures a much more stable outlet pressure compared to direct-acting regulators. It remains largely unaffected by fluctuations in the inlet pressure, providing consistent performance under varying conditions.

This regulator features 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 safety and reliability.

Constructed from die-cast aluminum, the body is lightweight and offers excellent heat dissipation. The protected bonnet and chamber design make it well-suited for demanding factory floor environments, combining durability with efficient thermal management.

Two adjustable pressure ranges are available to accommodate different application needs: 0.05 to 0.83 MPa for general use, and a low-pressure precision type ranging from 0.02 to 0.2 MPa. This flexibility allows for precise control tailored to specific requirements.

The regulator supports a variety of port sizes 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, ensuring compatibility with diverse piping systems.

For enhanced usability, an optional pressure gauge from the G46 series (indicated by the G suffix) and a mounting bracket (model B25P) are available. These accessories facilitate clear local pressure readings and simplify installation or retrofit processes.

To prevent accidental adjustments and pressure fluctuations after setting, the adjusting handle includes a locking screw. This feature ensures the regulator maintains the desired pressure without unintended tampering.
