Air Pressure Control Regulator
Precise air pressure control regulators maintain consistent airflow in compressed air systems, ensuring operational stability across manufacturing processes. These components deliver reliable pressure management for critical automation equipment.
- Product Introduction
Optimizing Industrial Pneumatic Performance
AR series pressure regulators keep stable air pressure inside compressed‑air lines, preventing fluctuating air pressure from damaging cylinders and solenoid valves. It comes in 5 housing sizes from 1000 to 5000 with wide thread options. You can choose models with or without mounting bracket and pressure gauge. Easy to take apart and service. Widely used on automation lines, packaging machines and jigs. Works as replacement for imported regulators, good for machine builders and bulk resellers.
Technical Specifications
Available in five series (AR1000 to AR5000) with port sizes spanning M5 to 10mm connections. Pressure adjustment ranges include:
- AR1000: 0.05-0.7MPa (0.51-7.1kgf/cm²)
- AR2000-5000: 0.05-0.85MPa (0.51-8.7kgf/cm²) or 0.02-0.2MPa option
Withstands 1.5MPa proof pressure and operates at 1.0MPa maximum working pressure. Temperature tolerance: 5-60°C for both environment and media.
Flow Performance
Achieves 550L/min flow capacity (AR2000-02 model) with 1/4" (BSPP) threaded connections. Compact 40mm width design enables high-density mounting configurations.
Key Functional Attributes
- Rotary Adjustment: Knob-controlled calibration with visual pressure indication
- Dual-Range Capability: Switch between standard and fine-pressure modes
- Integrated Mounting: Includes steel bracket for flexible orientation
- Temperature Compensation: Maintains accuracy across operating range
- Overpressure Protection: Automatic relief at 10KG threshold
Installation Advantages
1.Direct pipeline integration without auxiliary equipment
2.Horizontal or vertical orientation with bracket mounting
3.Tool-free adjustment during operation
4.Compatible with all standard pneumatic fittings
Industrial Applications
- Production line tooling pressure stabilization
- Pneumatic actuator control systems
- Packaging machinery air circuits
- Robotic end-effector supply lines
- Semiconductor manufacturing gas control
- Machine OEMs, equipment retrofitting shops, pneumatic parts wholesalers.
- Suitable for automation assembly lines, packaging machines, conveyor systems, tooling jigs, small CNC pneumatic circuits.
Operational Benefits
The rotary adjustment mechanism enables real-time pressure tuning during production cycles, minimizing downtime. Temperature-stable materials ensure consistent regulation despite environmental fluctuations - critical for plastic molding and CNC operations. Compact dimensions allow retrofitting into existing control panels with minimal space allocation.
Fluctuating workshop air supply causes inconsistent cylinder movement. Excess air pressure wears out seals on cylinders and solenoid valves. Some working sites need real‑time pressure reading. Different installation space requires versions with or without bracket. Long lead time and high cost for imported regulators.
Maintenance Features
- Zero lubrication requirements
- Diaphragm-less design reduces failure points
- Inline serviceability without system depressurization
- Visual pressure verification eliminates external gauges
Performance Validation
Tested to 100,000 pressure cycles without calibration drift. The brass construction resists corrosion in humid environments, outperforming aluminum counterparts. Units maintain ±1% accuracy across 85% of flow range, ensuring consistent tool performance in automotive assembly and electronic component manufacturing.
Safety Compliance
Meets ISO 6953-1 standards for pneumatic regulators and ASME B40.3 pressure gauge requirements. The overpressure protection system exceeds CE safety directives for industrial equipment, with fail-safe closure during supply pressure fluctuations.
These pressure management solutions particularly benefit food processing plants requiring washdown-ready components and laboratories demanding stable instrument air supply. The combination of precision control, compact engineering, and maintenance-free operation establishes this series as essential infrastructure for modern industrial facilities.
