Allen-Bradley 0-125 PSIG (0-9 Bar) Pneumatic Pressure Regulator

The Allen-Bradley 0-125 PSIG (0-9 Bar) Pneumatic Pressure Regulator is a reduced-pressure regulator that lowers and maintains downstream pressure at a constant setpoint despite fluctuations in inlet pressure. It is used in pneumatic and compressed air systems to protect downstream components and ensure stable operation, with common installations in air compressors, control panels, automation equipment, and process systems, where it maintains pressure for cylinders, valves, and other pneumatic devices. Key specifications include a 0-125 PSIG (0-9 Bar) adjustment range, compatibility with compressed air and inert gases, and an adjustment method of knob or screw; gauges are optional or integrated depending on model, and port size and connection type are OEM dependent (NPT or BSP). Mounting can be inline or panel, with body materials such as aluminum, brass, or zinc alloy, and operating temperature dependent on the OEM. Common replacements include Parker P3RA Series, SMC AR Series, and Norgren R07 Series.
