AR Series: High-Precision Control for Industrial Pneumatic Systems
The AR series (specifically the latest AR-A generation) is the global benchmark for pneumatic pressure regulation. Engineered to provide a stable air supply even under fluctuating inlet pressures, the AR series ensures your downstream equipment—such as solenoid valves and cylinders—operates at peak efficiency. Its compact, modular architecture makes it an essential component for modern, high-density machine designs.
Key Technical Features & Engineering Highlights
Space-Saving Modular Design: The AR series is built for seamless integration. Using standardized spacers and brackets, it can be combined with filters and lubricators to create a complete, customized F.R.L. assembly with a significantly reduced footprint.
Push-Lock Adjustment Knob: Features a reliable "Push-to-Lock" mechanism. Once the desired pressure is set, simply push the knob down to prevent accidental adjustments caused by vibration or human error.
High Flow Capacity & Low Pressure Drop: Optimized internal flow paths provide superior flow characteristics, ensuring that your actuators receive the air volume they need with minimal energy loss.
Versatile Pressure Options: Available in standard pressure (0.05 to 0.85 MPa) and low-pressure (0.02 to 0.2 MPa) versions to suit diverse applications from heavy-duty clamping to delicate air-blowing.
Backflow Function (AR-B Models): Optional integrated backflow mechanism allows for the quick and safe exhaust of air from the outlet side to the inlet side when the supply pressure is removed.
Multiple Gauge Configurations: Supports round analog gauges, square embedded gauges, or digital pressure sensors for real-time system monitoring.
