Norgren R72M-2GK-RFN Pressure Regulator - RoHS Compliant
Part Number: R72M-2GK-RFN
Quick Summary
R72M-2GK-RFN is a general purpose manifold pressure regulator for compressed air systems. In multi-regulator manifolds, keeping downstream pressure stable while avoiding cross-talk can be a real challenge. RoHS compliant materials support regulatory conformity; CE, SIL, or IP ratings are not specified in the data and may require confirmation for your application. With inline or modular installation and scalable manifold options, this regulator delivers reliable, repeatable performance across automation lines. The Excelon design supports easy integration with existing systems, helping procurement reduce risk and accelerate commissioning. For engineers and maintenance teams, this translates into fewer adjustments, tighter control, and improved overall production uptime.

FAQs
Begin by confirming the manifold porting matches G1/4 connections on the regulator. Mount the unit using appropriate Quikclamp or bracket options, ensuring the gauge port is accessible for calibration. Connect the inlet to a clean, dry compressed air supply and route the outlet to downstream regulators. Use the knob to adjust the outlet within 0.3–4 bar and verify with the gauge port. This approach minimizes cross-talk between adjacent regulators and accelerates commissioning in inline manifolds.
The regulator operates with a G1/4 port size, supports a 0.3 to 4 bar outlet pressure range, and allows up to 20 bar maximum inlet pressure. It is a relieving type regulator, which aids in safe venting of excess pressure. The device is designed for compressed air and features a knob-adjustable outlet, with a gauge port for verification and setup.
Yes. The Excelon design supports inline or modular installation, making it well-suited for packaging lines and automation tooling that require consistent downstream pressure across multiple regulators. Its compact footprint and compatibility with common mounting options simplify integration in crowded control panels, while the 0.3–4 bar adjustment range covers typical downstream needs without over-regulation.
The product data indicates RoHS compliance as a relevant certification, supporting regulatory conformity for reduced hazardous substances. CE, SIL, and IP ratings are not specified in the provided data and may require confirmation for regulated environments. For critical applications, verify with the supplier or reference documentation before deployment.
Maintenance is minimized through durable zinc diecast construction and nitrile elastomer compatibility, reducing leak risks and replacement intervals. Accessory options such as 18-015-989 gauges, Tamper Resistant Covers, mounting brackets, and Service Kit R74M support quick calibration, secure mounting, and streamlined servicing, helping maintain consistent performance and lowering total cost of ownership over time.
