Norgren R74G-6GK-RMN Excelon Pressure Regulator - Relieving
Part Number: R74G-6GK-RMN
Quick Summary
Norgren R74G-6GK-RMN Excelon pressure regulator delivers precise downstream pressure control for compressed air systems in automation. When downstream pressure spikes or dead-ends occur, system performance degrades and downtime increases. This model leverages the Excelon design for inline or modular installation, a balanced valve for stable control, and a push-to-lock knob with tamper-resistant accessory. Typical industrial certifications for regulators in this family include CE compliance and IP-rated variants, with SIL-capable options in higher grades. For procurement and maintenance, the compact form factor, clear pressure range, and robust materials support predictable costs and easier stock management in modern manufacturing environments.

Feature → Business Impact → Application: Inline or modular installation enables flexible panel design and faster retrofits, reducing installation time and field complexity while maintaining consistent performance in automation lines. This translates to lower commissioning costs and easier scalability for evolving processes such as packaging and automotive assembly. Feature → Business Impact → Application: Balanced valve design delivers stable pressure control with minimal oscillation, improving downstream reliability and reducing actuator wear in end-of-line machinery like pick-and-place systems and pneumatic gripping stages. Feature → Business Impact → Application: Relieving capability protects downstream equipment during dead-end events, preventing pressure spikes and potential component damage in presses and indexers. Feature → Business Impact → Application: Push-to-lock knob with tamper-resistant accessory minimizes accidental adjustments, yielding better process reliability and reduced maintenance incidents in high-turnover environments. Feature → Business Impact → Application: Rugged Excelon construction using die-cast aluminium and nitrile elastomers supports long service life under -34 to 80 °C ambient conditions, with a 20 bar max inlet and 0.3–10 bar outlet range, aligning with demanding plant standards and reducing replacement cycles. Feature → Business Impact → Application: G3/4 porting with Rc1/8 gauge port, plus inline installation compatibility and universal mounting options, simplifies integration with existing piping and brackets, decreasing installation risk and shortening project timelines.

FAQs
The R74G-6GK-RMN is designed for flexible installation, supporting inline panels or modular arrangements. With G3/4 port size and Rc1/8 gauge port, it integrates easily with standard piping and gauges. Utilize the 4324-50 'Universal' bracket for mounting and follow the included installation guide to ensure a secure, leak-free fit in control panels and equipment frames.
Key specs include a 0.3–10 bar adjustable outlet, up to a 20 bar maximum inlet pressure, and a flow capability of 105 dm3/sec (222 scfm). It is a relieving regulator with a knob-adjusted setting, suited for precise pressure control in compressed air systems and ensuring stable downstream pressure for actuators and valves.
Yes. The model is a relieving regulator designed to reduce downstream pressure when the system is dead-ended, protecting downstream devices from overpressure and allowing safe operation of connected actuators and pneumatic tools in automation lines.
The Excelon family is built for industrial environments and commonly supports CE-style compliance and compatibility with typical industry standards. For exact regulatory certifications on this specific unit, consult the datasheet and supplier certification statements, particularly if SIL ratings or IP classifications are required for your facility.
Maintenance can be supported by the R74G-KITR service kit, enabling field refurbishment of the regulator. Mounting is facilitated by the 'Universal' bracket (4324-50) and standard inline/modular configurations. For ongoing reliability, pair with the tamper-resistant knob option and ensure gauge port accessibility via Rc1/8 ports during routine calibration.
