Norgren V72G-3GK-NMN Excelon Relief Valve - PED 0/1
Part Number: V72G-3GK-NMN
Quick Summary
Norgren V72G-3GK-NMN pressure relief valve protects pneumatic equipment by limiting system pressure in compressed air lines. Industry teams often struggle with unpredictable over-pressurisation and risky field adjustments, which this model mitigates with a push-to-lock adjusting knob and tamper-resistant option. It meets PED Category 0(S.E.P.) and Category 1 from the Pressure Equipment Directive 97/23/EC. Together with Excelon's inline or modular installation, it provides reliable protection for OEMs and end users, supporting compliant, efficient pneumatic systems.

FAQs
The V72G-3GK-NMN supports in-line installation or modular integration with other Excelon products, allowing seamless expansion along a single pneumatic network. Field engineers benefit from a compact, push-to-lock adjusting knob and compatibility with common G3/8 and Rc1/8 fittings to minimize rework during upgrades.
Key specs include G3/8 port size, Rc1/8 gauge port, maximum inlet pressure of 10 bar, outlet pressure adjustment from 0.3 to 10 bar, and a rated flow of 27 dm3/sec (57 scfm). Operating temperature ranges from -34 to 65 °C, with a compact body weight of 0.33 kg and Excelon-series compatibility.
Yes. The unit meets PED Category 0(S.E.P.) and Category 1 under the Pressure Equipment Directive 97/23/EC, providing traceable compliance for safe operation in regulated pneumatic systems and helping simplify regulatory documentation for OEMs and end users.
Available accessories include the Excelon 3/2 modular shut-off valve (T72T-3GA-P1N), tamper-resistant cover and wiring (4255-51), a gauge (18-015-989) with R1/8 thread, and mounting brackets such as 74316-50 Neck Mounting Bracket, 4214-51 Quikclamp, 4214-52 Quikclamp with wall bracket, and 4224-50 'Universal' Bracket to suit different panel layouts.
The valve reduces downtime by preventing over-pressurisation, extends actuator life, and minimizes maintenance due to secure, tamper-resistant adjustments. Its inline/modular design lowers installation time and future reconfiguration costs, delivering faster deployment and improved process reliability in automation and tooling applications.
