Norgren R73G-2GK-RSN Pressure Regulator - Excelon Relieving
Part Number: R73G-2GK-RSN
Quick Summary
Norgren R73G-2GK-RSN pressure regulator provides precise pneumatic pressure control for automation systems. Many engineers struggle with downstream pressure fluctuations when lines dead-end or loads vary, leading to process variability and accelerated wear. The Excelon line supports CE conformity and offers variants with SIL-rated and IP-rated options, aligning with common safety and reliability benchmarks in pneumatic systems. This combination of precise regulation, modular installation options, and robust materials delivers measurable business value through reduced downtime, easier auditing, and safer, more predictable operation.

Inline or modular installation supports flexible system layouts, enabling closer placement to points of use and easier retrofits, which reduces piping length and response time while simplifying maintenance. The balanced valve design delivers steadier outlet pressure, improving regulation accuracy and extending the life of connected actuators in demanding automation lines. The relieving model minimizes downstream pressure spikes when the line is dead-ended, protecting sensors and cylinders from overpressure events and lowering the risk of leaks or component failure. The push-to-lock adjusting knob with tamper-resistant accessory helps maintain stable settings in environments with high personnel turnover or vibration, reducing set-point drift and unintended changes. With a maximum inlet pressure of 20 bar and an adjustable outlet range of 0.7 to 17 bar, engineers gain precise control across typical manufacturing cycles, while the gauge port Rc1/8 allows quick validation during commissioning. The Excelon body is diecast aluminum with zinc bonnet and nitrile elastomer seals, delivering durability in rugged plant conditions and predictable service life, supporting total cost of ownership reductions. The specified flow of 60 dm3/sec ensures adequate supply for standard automation applications without compromising performance in mid-to-high demand lines.

FAQs
The R73G-2GK-RSN supports inline installation or modular mounting, enabling flexible placement in tight spaces or near points of use. It uses a G1/4 inlet/outlet port and an Rc1/8 gauge port for pressure monitoring, with a durable die-cast aluminum body and zinc bonnet for robust field performance. This combination simplifies retrofits and future expansions while maintaining reliable airflow.
Key specifications include an outlet pressure range of 0.7 to 17 bar, a maximum inlet pressure of 20 bar, and a flow capacity of 60 dm3/s (127 scfm). It is a relieving regulator, featuring knob adjustment designed for easy set-point changes, and a gauge connection via Rc1/8. These specs deliver stable regulation across common pneumatic loads and environments.
Yes. The R73G-2GK-RSN is a relieving regulator that reduces downstream pressure when the system is dead-ended, protecting downstream devices and reducing pressure spikes. Its inline or modular installation supports proximity to actuators and sensors, improving response times and system safety while maintaining tight tolerance across varied loads.
Certification specifics can vary by region and configuration. The Excelon family typically aligns with common safety and regulatory expectations, with CE conformity and related safety ratings documented in regional documentation. For exact certifications on the R73G-2GK-RSN, consult the data sheet and installation guide or contact our technical team to verify compliance for your application and location.
To sustain performance, use the R73G service kit (R73G-KITR) and compatible accessories such as tamper-resistant covers (4455-51) or Quikclamps (4314-51/52). Regular checks of the adjusting knob, gauge port, and seals are recommended. The compact Excelon design reduces downtime, while modular mounting simplifies component replacement and spare parts planning, lowering total cost of ownership.
